In this study, methanol and ether extracts of five endemic Asperula species (Rubiaceae) from Turkey (A. antalyensis, A. brevifolia, A. pseudochlorantha, A. purpurea subsp. apiculata and A. serotina), used in the traditional system of medicine, were tested for antimicrobial activity by the agar well diffusion method and the broth dilution method. The most active species were Asperula brevifolia ...

Present study evaluated in vitro antioxidant activity and cytotoxicity of four important Piper species (P. nigrum L., P. chaba Hunter, P. longum L. and P. colubrinum Link.) and six black pepper varieties (Sreekara, Subhakara, IISR Malabar Excel, Panniyur-1, Panchami and IISR Thevam). It was performed with sequential extracts of the dried berries/fruits using n-hexane, chloroform, methanol and w...

general toxicity, antiproliferative, antibacterial and antioxidant activities of caulerpa peltata j.v.lamouroux (caulerpaceae) collected from oman sea were investigated. dried, ground alga was soxhlet-extracted with hexane, dichloromethane and methanol successively. the methanol extract was subjected to vacuum liquid chromatography (vlc) fractionation on silica gel using a step gradient of diff...

it has been reported that different species of euphorbia (euphorbiaceae) have antitumor activity. some reports also show that these plants have potential cytotoxic effect against different cell lines. in a program to screen the cytotoxicity of iranian native plants, euphorbia macroclada boiss. was collected, identified, and the cytotoxic activity of dichloromethane, ethylacetate, methanol extra...

In the present study, the antibacterial and DPPH radical scavenging activities of the leaf extracts and leaf essential oil of Syzygium cumini Linn were investigated. The antibacterial potential of the leaf essential oil, petroleum ether, chloroform, ethyl acetate and methanol extracts of the leaves of Syzygium cumini Linn were studied against human pathogenic bacteria viz. Bacillus cereus, Ente...

The rapid spread of multidrug-resistance against conventional antibiotics is a global threat that necessitates the search for alternative therapies from natural sources. In this study, the antibacterial potentials of chloroform and methanol extracts of mung bean sprout (MBS) or Vigna radiata (L) Wilzeck extracts were evaluated against Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumon...

the aim of the present study was to isolate cyanobacteria from oil refinery waste water and detection of antagonistic activity of their extracts on four species of pathogenic bacteria. the cyanobacterium was isolated and purified on blue green algae medium number 11 (bg-11) medium. methanol and water extracts prepared from the cultured cyanobacterium after 45 days growth on bg-11 medium. the bi...

The antibacterial activity of crude extracts of Sargassum longifolium and Gracilaria corticata collected from the Gulf of Mannar Coast, Tamilnadu, India against common shrimp pathogens were tested by disc diffusion method. Three different solvents namely aqueous, ethanol and methanol were used for extraction. The qualitative phytochemical analysis revealed the presence of carbohydrates, protein...
