Abstract
Phytochemical investigation was carried out on the crude methanol and aqueous extracts of the seeds of Harpullia arborea (Blanco) Radlk. (Sapindaceae). The antimicrobial activity of the extract was tested against standard strains and clinical isolates of some bacteria using the disc diffusion method. Preliminary phytochemical studies revealed the presence of glycosides, steroids, saponins and resins as the chemical class present in the extracts. The extracts showed inhibitory activity against clinical isolates of Bacillus subtilis, Salmonella typhi, Pseudomonas aeruginosa, Escherichia coli and Proteus vulgaris. The results showed that the methanol extract was more potent than the aqueous extract.

The antibacterial effect of some selected Indian medicinal plants was evaluated on bacterial strains like Bacillus cereus ATCC11778, Staphylococcus aureus ATCC25923, Enterobacter aerogenes ATCC13048, Escherichia coli ATCC25922 and Klebsiella pneumoniae NCIM2719. The solvents used for the extraction of plants were water and methanol. The in vitro antibacterial activity was performed by agar disc diffusion and agar well diffusion method. The most susceptible Gram-positive bacteria was B. cereus, w...
Abstract Antimicrobial activity of different concentrations (50, 100, 200, 300 and 500聽ml/l) of essential oil extracts of three type of onions (green, yellow and red) and garlic against two bacteria, Staphylococcus aureus , Salmomella Enteritidis, and three fungi, Aspergillus niger , Penicillium cyclopium and Fusarium oxysporum , was investigated. The essential oil (EO) extracts of these Allium plants (garlic and onions) exhibited marked antibacterial activity, with garlic showing the highest in...

Ethanolic and aqueous (cold and hot) extracts of Landolphia owerrience root parts (whole-root, root-bark and root-wood) were tested for activity against ten bacterial strains using agar-well diffusion and macro-broth dilution methods, respectively. The ethanolic extracts of the whole-root and root-wood were active against 100 and 80% of the test organisms, respectively. Ethanolic and aqueous extracts of the root-bark were moderately active while the aqueous (cold and hot) extracts of the root-wo...

Abstract Two new acylated triterpenoid saponins named pendulaosides A and B as well as the known phenolic compounds methyl gallate, gallic acid, 1,2,3,6-tera- O -galloyl-尾- d -glucose and 1,2,3,4,6-penta- O -galloyl-尾- d -glucose, were isolated from the seeds of Harpullia pendula . The structures of pendulaosides A and B were determined using extensive 1D and 2D NMR analysis and mass spectrometry as well as acid hydrolysis, as 3- O -尾- d -glucopyranosyl-(1鈫2)-[伪-L-arabinofuranosyl-(1鈫3)]-尾- d -g...
