We demonstrated previously that the aqueous root extract of Cryptolepis sanguinolenta (cryptolepis), with cryptolepine as the major constituent adversely affect reproduction and foetal development in mice. However, very little is known on the effect of prenatal exposure of cryptolepis on the post-natal life of surviving animals. Using murine models, we report here, the effects of prenatal exposure to cryptolepis on the growth and development of physical landmarks and sensorimotor systems. Prenatal cryptolepis (62.5, 100, 500 mg/kg; p.o) treatment of pregnant mice from gestation day 6 – 19 significantly caused a delay in eye opening and development of reflexes such as righting, mid-air righting, auditory startle and pinna reflex. Prenatal cryptolepis treatment also inhibited intrauterine growth but not post-natal growth. This study shows that prenatal cryptolepis treatment provokes functional toxicity by delaying the development of physical landmarks and sensorimotor systems in...

This research was focused on the qualitative and quantitative evaluation of anti-inflammatory and analgesic effects of ethanolic extract of Scindapsus officinalis (EESO) fruit in laboratory animals and whether these effects were of any statistical significance. Carrageenan-induced Hind Paw Edema test in long evans rat was the experiment for anti-inflammatory activity of the ethanolic extract of Scindapsus officinalis fruit while hot plate test was carried out to assess its analgesic activity in swiss albino mice. At two different doses of 250 and 500 mg/kg body weight, the analgesic test was evaluated on mice and the anti-inflammatory test was evaluated on rats by the ethanolic extract of the fruit. Phytochemical analysis of ethanolic extract of Scindapsus officinalis has indicated the presence of steroid, carbohydrate, flavonoid, alkaloid, tanin, saponin and terpenoid-compounds. Since these compounds are of pharmacological interest, coupled with the use of this plant in traditional medicine, prompted us for its possible analgesic and anti-inflammatory activities. The experimental activities for the ethanolic extract ofScindapsus officinalis fruit exhibited statistically significant (p<0.05) anti-inflammatoryactivity...

General phytochemical screening of the aqueous extract of fruits of Solanum xanthocarpum (Solanaceae) revealed the presence of steroids, terpenes, phenolic compounds, saponins, fatty acids, alkaloids. Fractionation of aqueous extract and activity guided isolation resulted in isolation of two white crystalline powder which were subjected to physical, chemical and spectral identification using IR, 1H‐NMR, 13C‐NMR and LC‐MS. On the basis of the spectral data analysis and chemical reactions, the compounds have been established as β-sitosterol and Stigmasterol....

ABSTRACT: Fifteen soil samples were collected from different locations near Nagpur i.e. from Nagpur, Bhandara and Chandrapur. Air drying and pre-treatment of soil samples with CaCo3 (1%) were found to be most effective for isolation of actinomycetes. Five different selective media were used for the isolation of actinomycetes and the best growth was observed in yeast malt extract agar medium with 1 mg/ml cycloheximide as antifungal agent and by using double layer agar technique for isolation. Significant differences were found between the counts of actinomycetes on different media. Total 78 actinomycetes species were isolated. More number of actinomycetes were isolated from Nagpur region (32 x 10 cfu/g) as compared to Bhandara (28 x 10 cfu/g) and Chandrapur (18 x 10 cfu/g) regions. Out of 78 isolates 23 isolates showed positive results in primary screening. Maximum isolates showed activity against B. subtilis, B. cereus, S. aureus and E. coli. Few isolates showed activity against P. vulgaris, P. aeruginosa, C. albicans and A. niger. Noactivity was seen against Penicillium sp. From...

The herbal preparation of the leaves of Solanum pubescens Pers (Solanaceae) is used in traditional medicine for the treatment of Epilepsy and febrile convulsions. A pilot study has confirmed the potency of the leaf of Solanum pubescens in the control of seizure in mice. The current study was aimed to identify the active phytochemical responsible for the activity. Results indicated that methanolic extract of Solanum pubescens at 300 mg/kg exhibited a significant P<0.05 delay in the latency of myoclonic spasms and tonic-clonic phase of seizure induced by PTZ, and also decreased the latency and increased the duration of phenobarbitone induced sleeping time. While the phytochemical studies showed the presence of alkaloids, resins, glycosides, carbohydrates, reducing sugar, fats and oils, flavonoids and terpenoids. The results suggested that the extract possessed anticonvulsant activity and central depressant effects which may be attributable to the...
