Many studies of root extract of Calotropis gigantea have been done to prove its potential as anticancer, antimicrobial, etc. agent C. gigantea plant itself is very easy to grow in tropical countries. However, studies of acute toxicity of C. gigantea root extract has not been performed.The purpose of this research was to know the safety level, the chemical constituents, and the acute toxicity of methanol extract of C. gigantea root bark given orally on Rattus norvegicus in rats. C. gigantea root bark was extracted by using methanol. The methanol extract was suspended in 1% sodium carboxymethyl cellulose (CMC) and administered orally by gavage (1250, 2500 and 5000 mg/kg) in separate groups. On the day of fifteen, all animals were anesthetized and some selected vital organs were excised, weighed and macroscopically examined. The liver was assessed histopathologically. There were no lethal effects, behavioral changes and no significant change in body and organ weights compared to control after the administration of the extracts. Thus, the value of LD50 for oral administration of methanol extracts from root bark of C. gigantea was larger than 5000 mg/kg. Methanol extract of C. gigantea root bark must be considered safe enough as none of the rats were died along the study. But, it can damage the hepatic cell, if given in higher dose. Dhaka Univ. J.

The methanol extract of Securidaca longepedunculata root bark was screened phytochemically and its intraperitoneal acute toxicity evaluated in mice. The phytochemical screening was carried out based on standard methods. The Median Lethal Dose (LD50 ) was determined using Lorke’s method while the Maximum Tolerated Dose (LD0 ) was determined by the method described by Mosser and Padilla. The root bark extract revealed the presence of carbohydrates, terpenoids, cardiac glycosides, saponins and flavonoids. The extract produced intraperitoneal LD0 and LD50 values of 6.92 mg/kg and 6.0 mg/kg, respectively. Based on the research findings, the methanol extract of S. longepedunculata root bark was found to contain important phytochemicals which may be attributed to its enormous use in traditional medicine, but it was a highly toxic extract in mice with intraperitoneal LD50 and LD0 values of 6.92 mg/kg and 6.0 mg/kg, respectively.

Zanthoxylum paracanthum Kokwaro (Rutaceae) is an endemic Kenyan and Tanzanian plant used in folk medicine by local populations. Although other Zanthoxylum species have been studied, only Z. paracantum stem extracts have been profiled, even though the roots are also used as herbal remedies. As root extracts may be another source of pharmaceutical compounds, the CH2Cl2/MeOH (1:1) root bark extract was studied in this report. Eight root bark compounds were isolated and their structural identities were confirmed by mass spectrometry (MS) and nuclear magnetic resonance (NMR) (using COSY, HSQC, NOESY and HMBC) analyses. The structural identities were determined as follows: the fatty acid—myristic acid (1); the sterol—stigmasterol (2); the lignan—sesamin (3); two β-carboline alkaloids—10-methoxycanthin-6-one (6) and canthin-6-one (7); and three phenanthridine alkaloids—8-acetonyldihydrochelerythrine (4), arnottianamide (5) and 8-oxochelerythrine (8). Some of these compounds were identified in the species for the first time. These compounds and the extract were then tested in vitro against methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 29213) and Candida albicans (ATCC 10231) before tests for antiproliferative activity against the human breast cancer (HCC 1395), human prostate cancer (DU 145) and normal (Vero E6) cell lines were conducted. Minimum inhibition concentration values of 3.91, 1.95, 0.98 and 7.81 µg/mL against MRSA, S. aureus, E. coli and C. albicans, respectively, were recorded. Among the isolates, canthin-6-one was the most active, followed by 10-methoxycanthin-6-one. The root extract and some of the compounds also had antiproliferative activity against the HCC 1395 cell line. Stigmasterol and canthin-6-one had IC50 values of 7.2 and 0.42. The root bark extract also showed activity, at 8.12 µg/mL, against the HCC 1395 cells. Out of the chemical isolates, 10-methoxycanthin-6-one and canthin-6-one showed the strongest inhibition of the DU 145 cells. The root extract had significant antimicrobial and antiproliferative activities, supporting the traditional use of this plant in treating microbial infections and cancer-related ailments.

Purpose: To examine the glucose uptake stimulatory activity of the root extract of Cissus javana DC. (Vitaceae) in Lδ myotubes of rat, and also to identify the extract’s active principles.Methods: The methanol extract was prepared from Cissus javana tuberous roots and evaluated for glucose uptake stimulatory effects on Lδ rat muscle cells and inhibitory activity against α-glucosidase. The chemical components were isolated using several chromatographic techniques, and their structures characterized by spectroscopic methods. Each isolate was then assayed for glucose uptake stimulatory and α-glucosidase inhibitory activities.Results: The extract (100 μg/ml) exhibited glucose uptake stimulatory effect (70.9 % enhancement) and α-glucosidase enzyme inhibitory activity (100 % inhibition). Through chromatographic separation, bergenin, stigmast-4-en-3-one and β-sitosterol were isolated and identified. Bergenin, at 100 μg/ml (0.3046 mM), increased glucose uptake by Lδ myotubes by 50.5 % without toxicity. At the same concentration, bergenin showed no inhibition on α-glucosidase enzyme, while stigmast-4-en-3-one and β-sitosterol exhibited 98.6 and 40.6 %, inhibition, respectively.Conclusion: This study is the first report on the chemical constituents, and the glucose uptake stimulatory and α-glucosidase inhibitory activities of Cissus javana DC. roots. The findings reveal the antidiabetic potential of the plant and the glucose-uptake enhancing activity of bergenin.

In this study, methanol extract from the root bark of Calotropis gigantea L. and its petroleum ether (40°C-60°C), chloroform and ethyl acetate soluble fractions were tested for their cytotoxic activity against brine shrimp nauplii (Artemia salina, Leach) and for antifungal activity against Aspergillus flavus, Aspergillus niger, Penicillium sp and Trichoderma harzianum. Thin layer chromatography (TLC) screening showed that methanol extract and its different fractions contained different type compounds such as steroid, terpene, glycoside, heterocyclic and flavonoid. In brine shrimp lethality bioassay, it was found that chloroform fraction was highly cytotoxic (LD50 14.72 μg/ml) among the tested samples. Though methanol extract and ethyl acetate fraction have no activity against all the tested fungi but petroleum ether and chloroform fractions showed potent activity against Aspergillus niger, Penicillium sp, Trichoderma harzianum and Aspergillus niger, Trichoderma harzianum, respectively, in antifungal activity test.  Key words: Calotropis gigantea; Methanol extract; Antifungal activity; Cytotoxicty.DOI: 10.3329/sjps.v2i2.2187Stamford Journal of Pharmaceutical Sciences Vol.2(2) 2009: 38-41

Background: Calotropis gigantea is a well-documented traditional medicinal plant useful for many disease conditions. The present study deals with the effect of alcoholic extract of roots bark of Calotropis gigantean in some animal models.Methods: Acute anti-inflammatory activity of root extract was assessed on carrageenin induced paw edema and chronic antiinflammatory activity on cotton pellet granuloma formation in rats and compared with standard diclofenac sodium. Antiasthmatic activity was assessed in histamine and actylcholine induced bronchoconstriction in guinea pigs.Results: 100 and 200 mg/kg p.o. root extract of CG showed significant anti-inflammatory and bronchodilator activity. Antiinflammatory activity was higher than Diclofenac Sodium 50mg/kg. The combination of low dose diclofenac sodium 25mg/kg potentiated the effect. Inhibitory effect on synthesis and release of various inflammatory mediators might contribute to both of these actions. Steroid like phytoconstituents might be responsible for these effects. Further research is needed to understand the exact mechanism behind these effects.Conclusions: In the present study Calotropis gigantea root bark exhibited anti-inflammatory activity in animal models.

Most of biochemical reactions in the body generates Reactive Oxygen Species (ROS), which are involved in the pathogenesis of oxidative stress-related disorders like diabetes, nephrotoxicity, cancer, cardiovascular disorders, inflammation and neurological disorders when they attack biochemical molecules like proteins, lipids and nucleic acid. Antioxidants are used to protect the cells or tissues against potential attack by ROS. Most medicinal plants possess a rich source of antioxidants such as flavonoids, phenols, tannins, alkaloids among others. These phytochemicals are currently pursued as an alternative and complimentary drug. In this study, phytochemical components, antioxidant and acute toxicity study of the methanol extract of stem bark and root of F. sycomorus were carried out using standard methods. Findings from this study revealed the presence of some diagnostic microscopical features such as calcium oxalate, starch, gum/mucilage, lignin, Aleurone grain, suberized/Cuticular cell wall and inulin but calcium carbonate was absent in stem bark but present in the powdered root. Quantitative physical constants include moisture contents (6.40% and 7.82%), ash value (7.20% and 9.30 %) in stem bark and root respectively. Carbohydrates, alkaloid, flavonoids, saponins, tannins, glycoside, steroid, triterpenes and phenols were present in all the extracts. They were found to exhibit potent 1,1,-diphenyl 2-picryl hydrazyl (DPPH) free scavenging activity. The DPPH radical scavenging ability of the extracts showed the following trend Ascorbic acid < stem bark extract˃ root extract. The LD50 of the methanolic stem bark and root extracts were found to be greater than 5000 mg /kg and is considered safe for use. Nonetheless, further

The present work is aimed to determine the chemical constituents in Baliospermum montanum methanolic extracts. An in vitro regenerated procedure was developed for the induction of callus from stem explant cultured on Murashige and Skoog (MS) medium fortified with various concentration and permutations of 2, 4-dichloro phenoxy acetic acid, 1-naphthalene acetic acid, 6-benzyl amino purine and gibberellic acid. FTIR &amp; GC-MS analysis was done according to standard procedure. The quantitative estimation of β-sitosterol was done by HPLC method. Maximum fresh and dry weight of callus was estimated in the combination of GA3 (0.5 mg/L) + NAA (2 mg/L) compared to other concentration. The FTIR analysis showed various functional compounds with different characteristic peak values in the extracts. Major bioactive constituents were recognized in the GC-MS analysis. Root extract revealed the existence of 1-hexadecanol, pentanoic acid, 2-(aminooxy)- and 1-hexacosanol. Leaf extract showed the presence of propanoic acid, 2-oxo-, trimethylsilyl ester, 9,12-octadecadienoic acid (z,z)-, trimethylsilyl ester, docosane, 1,22-dibromo- and pentatriacontane. Stem and stem derived callus exhibit the presence of 1,6,3,4-dihydro-2-deoxy-beta-d-lyxo-hexopyranose, n-hexadecanoic acid and pentanoic acid, 2-(aminooxy). The methanolic extract of leaf exhibited 0.2149 % of β-sitosterol content. There were no peaks observed in the root, stem and stem derived callus. Further studies are necessary for the isolation and characterization of bioactive compounds from B. montanum.
