antimicrobial activity of the roots of eranthemum roseum (vahl) r.br. (dasmuli), were tested against different bacteria (including escherichia coli, staphylococcus aureus, bacillus subtilis, shigella sonnei, klebsiella pneumoniae, salmonella typhi, proteus vulgaris, pseudomonas aeruginosa) and fungi (such as candida albicans and aspergillus niger) by cup plate diffusion method. minimal inhibito...

OBJECTIVE To evaluate the effect of different fractions of Black Maca (Lepidium meyenii), obtained from the hydroalcoholic extract, on spermatogenesis. DESIGN Animal study. SETTING Animal and laboratory facilities at a university. ANIMAL(S) Forty two adult male rats from the Holtzman strain (3 months old). INTERVENTION(S) Hydroalcoholic extract of Black Maca was partitioned with the fol...

The present study evaluate the anti-inflammatory activity of petroleum ether extract, ethanolic extract and aqueous extract of ocimum sanctum Linn (karunthulasi leaves). Extract was carried out using soxhlet apparatus. These three extract were subject to phytochemical analysis in order to find out the constituents present in the sample. Secondly, HRBC membrane stabilization was selected for fur...

Fresh leaves of vitex negundu were collected and macroscopic and microscopic characters were determined. Soxhlet extraction of the powdered leavers was carried out using petroleum ether (40:60) and chloroform. Idenitification of important phytoconstituents was carried out. Characterization by TLC showed the presence of vitexin. The processed leaf extract was tested for antimicrobial activity. T...

The protective effect of the petroleum ether fraction of the indigenous drug Cardiospermum halicacabum against electroshock induced convulsions in rats was studied. Alcoholic extract of the petroleum ether fraction of Cardiospermum halicacabum in the dose of 350 mg/kg body weight was effectively reduced the extensor an flexor component of tonic convulsions in electroshock induced convulsions in...

Antibaterial activity against Escherichia coli, proteus vulgaris, pseudomonas aeruginosa and staphylococcus aureus was tested for the petroleum ether (60-80°C) chloroform and aqueous leaf extract of strobilanthus kunthiana by disc diffusion method. Profound antibacterial activity was observed for all the leaf extract.

Column chromatography of the alcoholic extract of Piper betle roots furnished aristololactam A-II and a new phenyl propene, characterized as 4-allyl resorcinol, while the petroleum-ether extract yielded a diketosteroid, viz. stigmast-4-en-3,6-dione. All these compounds were characterized by spectroscopic means. Isolation of these compounds from this source is being reported here for the first t...

Basic organic drugs were extracted into ethanol from urine saturated with potassium carbonate. Drugs in this concentrate were purified by extraction into ether at pH 8.5. The ether extract was evaporated and applied to several thin-layer chromatograms. Functional-group detection was used in qualitative and semiquantitative analysis of the developed chromatograms by spraying the plates sequentia...

A new antibiotic, named seitomycin (1c), and the known microbial metabolite tetrangulol methyl ether (2) were found in the ethyl acetate extract of two terrestrial Streptomyces sp. isolates. The structure of the new antibiotic was elucidated by spectroscopic studies and by comparison of the NMR data with the structurally related hatomarubigin C (1a) and SM-196 B (1b). Seitomycin (1c) showed mod...
