Quorum sensing controls the virulence determinants in most proteobacteria. In this work, the hexane, chloroform and methanol extracts of an Ayurveda spice, namely clove (Syzygium aromaticum), shown anti-quorum sensing activity. Hexane and methanol extracts of clove inhibited the response of C. violaceum CV026 to exogenously supplied N-hexanoylhomoserine lactone, in turn preventing violacein pro...

Hexane, chloroform, ethyl acetate and methanol extracts of Strychnos nux-vomica Linn. (Family: Loganiaceae) and Semecarpus anacardium Linn. (Family: Anacardiaceae) were incorporated in semi-synthetic diet at 0.5, 1.0, 1.5 and 2% concentrations. Screened for antifeedant, larvicidal, pupicidal and adult malformation activities against Helicoverpa armigera (Lepidoptera: Noctuidae). The chloroform ...

Impact of brown seaweed, Padina pavonica (Linn.) chloroform, and benzene extracts were evaluated against an economically important cotton pest, Dysdercus cingulatus (Fab.) (Pyrrhocoridae). The result reveled that between the two solvents, benzene extracts of P. pavonica caused more nymphal mortality. It reduce D. cingulatus egg hatchability than chloroform extract. Benzene extract also reduced ...

Clinacanthus nutans Lindau leaves (CN) have been used in traditional medicine but the therapeutic potential has not been explored for cancer prevention and treatment. Current study aimed to evaluate the antioxidant and antiproliferative effects of CN, extracted in chloroform, methanol, and water, on cancer cell lines. Antioxidant properties of CN were evaluated using DPPH, galvinoxyl, nitric ox...

The binding of polyphosphoinositides (phosphatidylinositol phosphate and phosphatidylinositol bisphosphate) to the antibiotic neomycin is utilized for the purification of these lipids. Neomycin is reductively coupled to reactive glass beads (Glycophase-CPG) and serves as the stationary phase in column chromatography. A total lipid extract is prepared from tissues with chloroform-methanol-KC1 or...

Allamanda violacea is an ornamental plant of the genus Allamanda belongs to family Apocynaceae. Different flower extracts of the plant have been reported to possess anti-hyperlipidemic, anti-hyperglycemic and anti-oxidant activities. Present study deals with the identification of phytochemical constituents of the petroleum ether (pet ether) and chloroform extract by GC-MS analysis, and the cons...

The chloroform extract of Ferula persica var. persica roots was found to inhibit red pigment production of Serratia marcescens. A bioguided fractionation study by preparative thin layer chromatography (PTLC) detected a fraction (Rf = 0.71, petroleum ether/EtOAc, 2:1 v/v), which was effective on depigmentation of Serratia marcescens. Using conventional spectroscopy methods, the active fraction w...

Phytochemical screening of Geigeria alata leaves revealed the presence of flavonoids,tannins and alkaloids. A flavonoid compound Iwas isolated from ethanol extract by column and thin layer chromatography and its structure was established on the basis of its spectral data (IR, UV, NMR and MS). Compound I and different fractions (ethanol, chloroform, nbutanol and ethyl acetate) of Geigeria alata ...

The antibacterial activity of methanol, ethanol, chloroform, and hexane extracts of the leaves of Himalayan gymnospermous plant Ginkgo biloba L. was assessed against five animal and plant pathogenic strains (Agrobacterium tumefaciens, Bacillus subtilis, Escherichia coli, Erwinia chrysanthemi, and Xanthomonas phaseoli) employing disc-diffusion and broth-dilution assays. The methanol extract show...

Chloroform and methanol root and shoot extracts of A. aspera showed good amount of antibacterial activity against Klebsiella sp. While pet. Ether (60-80°) root extract showed the activity against B. Substilis only antifungal activity of roots was found in extracts with pet ether, chloroform and methanol against fusarium sp. only. Methanol and Aqueous shoot extracts were weakly active against Pe...
