 ABSTRACT

Plants are used long before antiquity for medicinal functions. Herbal medicine is a major part of both the conventional and modern medicine systems. In 2002, the Organization for Food and Agriculture estimated that over 50,000 medicinal plants are used worldwide. In 2016, the Royal Botanic Gardens, Kew, reported more conservatively that 17,810 plant species have a medicinal use, out of some 30,000 plants for which some form of use is known. Medicinal plants are considered to be a rich source of ingredients that can be used in the development of either pharmacopoeial, non-pharmaceutical or synthetic drugs. Datura stramonium is a medicinal plant of the order of the Solanales family, the Solanaceae family. Plant due to its therapeutic and narcotic activity used as ancient traditional knowledge healthful herb, this plant includes many primary and secondary metabolites, primary metabolites directly accountable for the growth, regulation and development as carbohydrates, protein, fatty acids, mineral and secondary metabolites or Phytochemical like alkaloids, phenols, flavonoids, tannis, saponins etc. biological activites as cytotoxic. Anti-inflammatory drug, inhibitor, analgesic properties. These medical specialty activites created the plant potent to targeted organism and promote the healthful aspects of phytomedicines in medicine industries.

INTRODUCTION

edicinal plants from the ancient time have been used to prevent living organism from ailment. From the Vedic era Ayurvedic, Siddha, Unani techniques has been practicised for therapeutic potential. In India around 4.5 million plant species are present in which 250,000-500,000 possesses medicinal properties (Bamola et al., 2018).
The genus name Datura is derived from dhatura, the Bengali name for the plant (Joy et al., 1998). Datura species, also called thornapple, devil’s apple, angel’s trumpet (in a broad sense) or devil’s trumpet, have their main center of origin in Mexico and the south-west United States (US) (Symon & Haegi 1991, Luna-Cavazos et al., 2009). Today, representatives of the genus Datura are considered as cosmopolitan and naturalized in many regions with tropical and temperate climate conditions (Benítez et al., 2018). In most parts of India Datura stramonium grows as a wasteland weed (Oudhia et al., 1998, 1999) but is cultivated for its alkaloids in some parts of India and in Europe (Chandra & Pandey 1989). There is a group of nine incredible species (Datura stramonium, Datura ferox, Datura quercifolia, Datura pruinosa, Datura leichahhardtii, Datura inoxia, Datura discolor, Datura metel, Datura wrightii) in the Datura genus, but the two famous species are D. inoxia and D. strammonium (Buchholz et al., 1935; Palazo´n et al., 2006). Other species of Datura reported in India include Datura innoxia Mill. (syn. D. metel Sims), common name sadahdhatura; and Datura metel L. (syn. D. alba Nees Syn. D. fastuosa L. common name kaladhatur. Datura stramonium is a medicinal plant with antinociceptive (Abdollahi et al., 2003) antioxidant (Couladis et al., 2003), hypolipidemic (Resekh et al., 2001), anti-inflammatory, anti-rheumatoid (Tariq et al., 1989), and hypoglycemic properties (Gharaibeh et al., 1988). The plant was used by Red Indians for many years as euphoric agent and since the 1800’s, used as a therapeutic agent and in Great Britian (Dessanges, 2001). It is a hallucinogenic plant that causes serious poisoning. Cases of poisoning have been reported after eating the berries. Death may occur from heart failure after ingesting 125 seeds, because the seeds contain the highest concentration and has a rapid onset of action, thus may be potentially useful as an alternative to atropine for the treatment of the muscarinic symptoms of organophosphate toxicity and some of central anticholinergic effects. The wide distribution, the strong toxicity and the potential for occurrence in foodstuffs are responsible for the numerous incidents in humans (Das et al., 2012). The deadly dose for adults is 15-100 g of leaf or 15-25 g of the seeds (Nayyar et al., 2020). The 2005–2017 annual reports of the HTIS were reviewed to identify plant-related poisoning cases (Kerchner & Farkas, 2020).
Morphology
Datura stramonium is a bushy, smooth, foetid annual. The branching stem is spreading and leafy. Leaves are generally light dull green, ovate to triangular ovate. Flowers are axillary, erect, white, and sweet scented (especially at night). The average length of flower is about 3 inches. Fruits are as large as walnuts and full of thorns (hence the English name "thorn apple"). Seeds are black (Lindley 1985). D. Stramonium bears funnel shaped, white or purple colored flowers, with 5 stamen and superior ovary. The ovary is bilocular at the upper part and quadrangular on lower portion. Leaves are very thin, brittle, shortly petiolate and unequal at the base. The apex is acuminate and margin is dentately lobed or irregularly serrate. Flowers are solitary, about 7.5cm in length. They arise in the axil, where from the stem forks, and are erect with a short pedicel. Calyx is about 3.5 cm and sharply folded. Corolla is funnel shaped. Five stamen and superior ovary, which is bilocular in the upper part and quadrangular in lower part, are present. Leaves have smooth cuticle followed by a layer of wavy epidermal cells. Palisade in single layer is present on upper surface only. At the base of the palisade tissue, crystal layer is present. The midrib shows a bicolateral structure. Upper and lower hypodermal collenchyma characteristics to midrib.  Epidermis shows numerous multicellular conical trichomes. Short glandular occasionally present on both the surfaces (Soni et al., 2012).
Chemical constituents of Datura stramonium
Extensive research has been carried out since 1925 for the isolation and characterization of the total alkaloid contents in Datura species (Berkov et al., 2006). Vitale et al. (1995) has shown that the total alkaloid content in Datura varies from 0.02 to 0.52% and scopolamine from 0.0029 to 0.32% relative to the dried material, depending on the geographical area, the part of the plant studied and the stage of growth.The amount of   total alkaloids found in drug is 0.2- 0.5 percent, in which hyoscyamine and hyoscine is principle alkaloid along with small quantities of atropine (dl-hyoscyamine). Hyoscine occurs in high quantity in young leaves. However /- hyoscyamine content of fully grown plant is more i.e. up to 2/3rd of total  alkaloids. The percentage of alkaloids is very less in stems and hence pharmacopoeia limits its content to 3 percent. The atropine and scopolamine concentration of D. stramonium seeds was determined as 1283 and 678 μg/g, respectively (Caligiani et al., 2011). The seed contain 0.2 percent of alkaloids and about 25 percent of fixed oil. Atropine is found to have more exciting properties, while scopolamine has more relaxing and hallucinogenic properties (Weitz, 2003). Isolectins have been isolated from D.stramonium seeds. Two of these lectins are homodimers  made up of either  A/B  subunits  while  the  third  is  a  heterodimer composed  of  one  A  and  B  subunit  with  approximate molecular  weights  of  32,000  and  28,000  respectively (Broekart et  al.,  1998). Datura lectins show its greatest affinity for glycopeptides. The different domains  contain many  contiguous  hydroxyproline  residues  which  are glycosylated and other  which lack glycosylated residues, have  higher  proportions of  cysteine  residues  containing the binding sites. The structure of the glycosylated region of these lectins is  similar  to  that  of  hydroxyproline  rich  glycopeptides  of plant  cell  wall  and these  lectins  could  be  precursors  for such material (Desai et al., 1981). Seeds yield diploid I and tetraploid II other than alkaloids (Monira & Munan, 2012; Bo et al., 2003; Bellila et al., 2011).
The major tropane alkaloids hyoscyamine and scopolamine and several minor tropane alkaloids have been identified in Datura species. Typical examples of minor alkaloids in D. stramonium are tigloidin, aposcopolamine, apoatropin, hyoscyamine N-oxide and scopolamine N-oxide17-20. 6â-ditigloyloxytropane and 7-hydroxyhyoscyamine are reported for the first time in this species (Das S et al., 2012). During the past ten years, an extensive effort has been put forth for the isolation and determination of alkaloids in plant materials. Using high  end  techniques  such as High Performance  Liquid  Chromatography  (HPLC)  and  Gas Chromatography  Mass  Spectroscopy  (GC-MS)  the alkaloids,  tropanes  and  withanolides  have  been  isolated and given in Table 2.

ETHANOPHARMACOLOGY (Das et al., 2012)

• Datura is internally used in relieving the spasm of bronchitis in asthma. It is also used in the treatment of Parkinsonism and Hemorrhoids. It leaves, applied after roasting are useful in relieving pain.
• Datura is internally used for treating giddiness, dry mouth, hallucinations and coma.
• Externally, the plant is used as a poultice in treating fistulas, abscesses wounds and severe neuralgia.
• The bitter narcotic plant relieves pain and encourages the healing process. The plant has a very long history of being used as herbal medicine.
• The growing plant works as an insect repellant, which protects neighboring plants from insects.
• The seeds of Datura are analgesic, anthelimintic andante-inflammatory and as such, they are used in the treatment of stomach and intestinal pain that results from worm infestation, toothache, and fever from inflammations.
• Its leaves, containing hyoscyamine and atropine, can be used as an immensely powerful mind- altering drug.
• Its leaves, flowering tops and seeds have anodyne, antiasthmatic, antispasmodic, hallucinogenic, hyponotic, mydriatic and narcotic properties. The seeds of the plant are the most active medicinally.
• Trace of scopolamine is also found in the plant, which is a potent cholinergic-blocking hallucinogen that has been used to calm schizoid patients.

  The juice of its fruit is applied to the scalp, to treat dandruff and falling hair.

Pharmacological properties of Datura stramonium
Antiasthmatic: With mild airway obstruction, Datura stramonium cigratte worked as good bronchodilator for asthmatic patients. Inhaling the smoke of one Datura cigarette by 12 asthmatic patients with mild airway obstruction substantially decreased specific airway resistance in 11 patients, the mean maximal decrease being 40% at 30th minute. In seven patients, subsequent inhalation of 200 micrograms salbutamol caused no further decrease in airway obstruction (Charpin et al., 1979). Datura stramonium plant has various phytochemical including atropine, scopolamine and hyoscymine. Scopolamine & atropine manifested anticholinergic properties and responsible for the blocking of M2 receptor of submucosal gland cell and smooth muscles of air pathway, In an observation when pregnant womens took Datura stramonium for asthma treatment, with the constant releasing of acetylcholine, nicotinic receptor could desensitize finally result displayed in as damage fetus (Pretorius & Marx, 2006). Significantly higher serum levels of pancreatic polypeptide in patients with bronchial asthma and chronic bronchitis during attacks are decreased after the use of D. stramonium (Zhang, 1989). Exposure of the foetus to this plant when a mother uses it for asthma, will cause a continuous release of Ach, resulting in the desensitizing of nicotinic receptors, this could ultimately result in permanent damage to the foetus (Pretorius & Marx, 2006).
Analgesic: D. stramonium seed extract has an analgesic effect on both acute & chronic pain which were produced by hot plate and formalin tests, point out that pain was condensed dose dependently with Ed values = 25 and 50 mg/kg. The whole plant is toxic, particularly the foliage and seeds (Khalili et al., 2004). Aqueous extract of D.  fastuosa leaves and  seeds  (10% w/v) were taken to evaluate the analgesic effect on acetic acid induced writhing pain and hot plate reaction in mice. Oral  treatment  of  400  and  800  mg/kg  proved  effective and  showed  significant  analgesic  effect.  Upon naloxone administration, analgesic effect was reduced in leaf extract while the seed extract remained unaffected. Swiss mice under standard environment conditions were subjected to i.p. acetic acid injection (0.6%, 10 ml/kg) and hot plate to check the analgesic effect (Abena et al., 2003). Aqueous seed extract of D.  metel  L. was  found not  to possess  analgesic  activity  on acetic  acid induced  model as  well as  the  radiant  heat  tail-flick  model  (Wannang  et al., 2009).
Antioxidant.  Investigation of anticancer activity by methanolic seed extract of Datura stramonium through DPPH radical scavenging, ABTS+ radical cation, Nitric oxide radical, Ferric reducing power assay and gained values as 35.26, 10.50, and 49.36 (Iqbal et al., 2017). On behalf of in vitro study of highest free radical scavenging effect DS showed the 6.7±0.1 µg/ml inhibitiory concentration value (Sreenivasa et al., 2012). The antioxidant activity of the plant extract was assessed on the basis of the free radical scavenging effect, using modified DPPH method. Datura stramonium leaf extracts exhibit potent antioxidant property. Graph 2 shows that the fatty acids of the Datura plant recorded the highest free-radical inhibitory (DPPH) for concentration (500µg/ml) and Ration (32.22%), and The lowest inhibition ratio was (12.44%) for concentration (200µg/ml), as compared with the standard sample (L-Ascorbic acid) which was much better than fatty acids at the same concentration. The results show that alkaloids compounds of Datura plant are better than fatty acids in inhibiting free radicals, possibly because alkaloids compounds have more hydroxyl groups. (Hasan et al., 2019).
Larvicidal and repellent activities: The ethanolic extracts of leaves of Datura stramonium were evaluated for larvicidal and mosquito repellent activities against Aedes aegypti stephensi and Culex quinquefasciantus. The LD50 values for larvicidal activity were found to be 86.25, 16.07 and 6.25 ppm against Aedes aegypti, Anopheles stephensi and Culex quinquefasciastus.  The ethanolic leaves extract of Datura stramonium provided complete protection time (mosquito repellency) of 2.73, 71.66, 117.7 mins against these insects at 1% concentration (Swathi et al., 2012).
Antifungal activities: Many medicinal plant together with Datura stramonium acquired antifungal effect (Sharma et al., 2002). The hexane, chloroform, acetone and methanolic fractions of D. metel  L.  were investigated  for  antifungal properties against three species of Aspergillus, that is, A. fumigates,  A.  flavus,  and A.  niger (Rajesh  &  Sharma, 2002). Antifungal activity of a concoction brewed from D. stromonium, Calotropis gigantea, A. indica (neem) and cow manure (T1) followed by methanol-water (70/30 v/v) extracts of D. stromonium, Calotropis gigantea and A. indica T2 against Fusarium mangiferae. The study proved that the concoction-brewed compost T1 is effective, inexpensive, easy to prepare and constitutes a sustainable and eco-friendly approach to control floral malformation in mango when it is sprayed at bud break stage and again at fruit set stage (Usha et al., 2009).
Organophosphate poisoning: Since D. stramonium contains atropine and other anticholinergic compounds, it is a useful remedy for the central cholinergic symptoms of organophosphate (OP) poisoning. Bania et al., determined the beneficial effect of Datura seed extracts following a severe OP poisoning. According to their experiment, D. stramonium seeds were heated in water to make 2 mg/mL atropine solution and administered to male rats as a single intraperitoneal injection 5 min before the subcutaneous injection of 25 mg/kg of dichlorvos. Pretreatment with Datura seed extracts significantly increased survival in a rat model of severe OP poisoning (Bania et al., 2004). Treatment of patients following an organophosphate (OP) exposure can deplete a hospital's entire supply of atropine. Given the possibility of multiple severe exposures after a terrorist attack using OP nerve agents, there exists a need for either greater atropine stores or the development of alternative antidotes. Jimsonweed (D. stromonium) contains atropine and other anticholinergic compounds and is common and readily available. It is used recreationally for its central anticholinergic effects and is easy to be made into an extract by boiling the crushed seeds. The extract has rapid onset of effects and may be useful for treatment of OP poisoning. (Theodore et al., 2004).
Acaricidal, repellent and oviposition deterrent properties: The ethanolic extracts obtained from both leaf and seed in the thorn apple were investigated for acaricidal, repellent and oviposition deterrent properties against adult two-spotted spider mites (Tetranychus urticae Koch) under laboratory conditions. Leaf & seed extracts, which were applied in 167,250 and 145,750 mg/l concentrations, respectively caused 98% and 25 % mortality among spider mite adults after 48 h (Nabi et al., 2009).
Antimicrobial activity: Worked on review of many medicinal plants of Bulgaria including Datura stramonium explained their antimicrobial, antioxidant, anti-inflammatory activity (Ivancheva et al., 2006). The anti-microbial activity of combined crude ethanolic extract of D. stromonium, Terminalia arjuna and Withania somnifera in cup plate diffusion method for antibacterial and antifungal activity. The extracts were subjected to screening to detect potential antimicrobial activity against Staphylococcus aureus, Bacillus subtilus, Escherichia coli, Klebsiella pneumoniae, Micrococcus luteus and Candida albicans with compare Ciprofloxacin standard drug (Sharma, Sharma, 2010). The methanol extracts of D. stromonium and Datura inoxia showed activity against Gram positive bacteria in a dose dependent manner. Little or no antimicrobial activity was found against Escherichia coli and Psuedomonas aeruginosa (Takhi, Ouinten, 2011). Aerial part (mainly stem and bark) of Datura stramoniums aqueous and ethanolic extract opposite to Eschericia coli, Salmonella typhi, Staphylococcus aureus, Klebsiella pneumonia, Shigella and Neisseria gonorrhea revealed that ethanol extract of the plant contains higher antimicrobial potential than aqueous extract but not in Neisseria and only Staphylococcus aureus displayed action to aqueous extract (Shagal et al., 2012). Methanolic extract of different parts of Datura leaves shows higher antimicrobial efficacy on Staphylococcus aureus ATCC25923 and Escherichia coli ATCC25922 by even small amount (Sreenivasa et al., 2012). D. stramonium was very effective as vibriocidal against various strains of Vibreo cholera and Vibreo parahaemolyticus. The minimum inhibitory concentration (MIC) value of acetone extracts of D. stramonium was in the range of 2.5 to 15 mg/mL serving as broad-spectrum vibriocidal agents (Sharma et al., 2009). After  extraction of  Datura stramonium  extract in  Soxhlet  using  methanol as  a solvent,  extract was subjected  to various  quantitative phytochemical  analysis result  of  phytochemical analysis. The zone of inhibition produced by Datura stramonium leaf extract against microorganisms is observed and noted antimicrobial activity of methanol extract of Datura stramonium 16mm, 19 mm, 18mm,19mm against different bacterial species Bacillus thuringiensis, seudomonas aeruginosa, Agrobacterium tumefaciens and Klebsiella pneumonia respectively.  Standard antibiotic (Azithromycin) was used as a positive control and Methanol was used as a negative control (Deshmukh et al., 2015).
Toxicological Evaluation of Datura Stramonium in Rats: In 3 months or 90 days subchronic study of different percentage of Datura seed (0.5, 1.58 and 5.0) containing diet were given to male and female rats with the 2.71 and 0.66 mg alkaloids and atropine respectively. Many observation including body weight, water intakes, gross clinical observation and feed were observed and recorded (weekly) with the pupil dilation and tears production (in whole study). The plant seed exhibited many effect on rats as decreased serum calcium, body-weight gain and serum albumin; increased serum alkaline phosphatase, testes weights, blood urea nitrogen and liver. Female rats displayed reactions more efficiently than male by decreasing cholesterol, serum total protein and increased Red Blood Cell Count, transaminase, Chloride and serum glutamicpyruvic transaminase (Dugan et al., 1989).
Anticancer activity: An integrated approach is needed to manage cancer using the growing body of knowledge gained through scientific developments. Thousands of herbal and traditional compounds are being screened worldwide to validate their use as anti-cancerous drugs. D. stromonium in therapeutic dose of 0.05-0.10 g was used to cure cancer. Likely unsafe produce vomiting, hypertension, loss of consciousness may lead to coma but may interact with anti-cholinergic drugs (Balachandran & Rajgopal, 2005). Cancer inhibiting effect on head, neck (FaDu), Breast (MDA-MB231), lung (A549) cancer cell line in in vitro condition by Datura stramonium leaf- aqueous extract (1mg/mL) for 24 & 48 hrs. respectively anticipated that plant parts possesses toxicity against living cells with increasing GSSG and agitating oxidative stress as well as considered changed quantity of enzyme which expresses redox sensitivity (Ahmad et al., 2009). Worked against cancer cell of breast (specially MCF-7 cell line) through MTT assay with methanolic extract of leaves and stem of Datura spp. and compared it with vero line, resulted that leaf extract expressed higher anticancer property against MCF-7 cell and vero cell line as compared to stem extract (Kumaresan et al., 2014).
Other activities: Datura stramonium seed extract among ethanol, chloroform, and acetone has strong insecticidal efficacy than methanol and n-hexane (Jawalkar et al., 2016). Whole plant of Datura stramonium has noxious property and because of that aqueous leaf extract of plant stated strong nematicidal activities (Sharma et al., 2002). Cholinergic compound esters exhibited effectual antiperspirant activity and Scopolamine; hydrobromide also rendered this potential with the higher skin incisive property (Millan et al., 1964). An extract prepared from the seeds of the DS possess activity typical of a protien haemagglutinin or lectin. The extract is capable of agglutinating erythrocytes from several species, and is non-specific with regard to human ABO blood groups (Kalpatrick et al., 1978). Though the antiepileptic activity of D. stramonium has not been reported yet, combination therapy with other herbs has the protective effect on status epilepticus. An experimental model of status epilepticus was induced in male rats and the results of this experiment strongly suggest that the appropriate combination of herbs with D. stramonium may be helpful as adjunctive interventions to treat epilepsy (Peredery & Persinger, 2004).
