The effects of the crude, methanol, hexane TLC and acetone extractable portion of strebulus as per on frog's heart and smooth muscle of rabbit were studied. The different extracts of S. asper showed a stimulant effect on frog's heart while the crude and methanol extracts showed not much alteration in the peristaltic activity of smooth muscle or rabbit. Methanol, hexane and acetone extractable p...

Thiobacillus novellus was able to grow with oxalate, formate, formamide, and methanol as sole sources of carbon and energy. Extensive growth on methanol required yeast extract or vitamins. Glyoxylate carboligase was detected in extracts of oxalate-grown cells. Ribulose bisphosphate carboxylase was found in extracts of cells grown on formate, formamide, and thiosulfate. These data indicate that ...

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...

The aim of this study was to investigate and compare Vaccinium myrtillus L. extracts obtained in ultrasonic condition with different water/methanol and water/ethanol extraction mixture acidified with 0.1% HCl. The extracts were analyzed for monomeric anthocyanins contents, total phenolics content and antioxidant activities. The highest anthocyanins content (3888 mg/L), total phenolics content (...

Introduction; The efficacy of Tagetes minuta (Asteraceae), Acalypha fruticosa (Euphorbiaciae) and Tarchonanthus camphoratus (Compositae) extracts were evaluated for the control of Phlebotomus duboscqi while incorporated in sucrose. This is the first time plant extracts have been used in sucrose baits against sand flies as opposed to environmentally unfriendly synthetic insecticides. Materials a...

BACKGROUND Gonorrhea is a major sexually transmitted disease worldwide and for its control, effective treatment is essential. However as more strains of Neisseria gonorrhoeae continuously develop resistance to several drugs, this strategy obliges scientists to discover newer effective drugs. OBJECTIVES To ascertain whether crude leaf and root extracts of Cassia alata (Caesalpiniaceae) have an...

The objectives of this study was to evaluate the possible in vitro antioxidant potential and analysis of the active polyphenols in ethyl acetate and methanol extracts of leaves of Leonurus sibiricus L. Alcoholic extraction of Leonurus sibiricus leaf was carried out in two different solvents (ethyl acetate and methanol) on the basis of their different polarity. The in vitro antioxidant efficacy ...

The study was carried out to investigate the antimicrobial, antioxidant potential and the qualitative and quantitative phytochemical analysis of the bark and leaf of Cocculus laurifolius DC. by using polar and non-polar solvents, i.e. Petroleum ether, Chloroform, Methanol and distilled water. Chloroform bark extracts showed maximum % yield. Antimicrobial activity was determined by using 4 bacte...

The present study deals with phytochemical and anthelmintic evaluation of corm of Amorphophallus campanulatus. This evaluation revealed the presence of many phytochemical constituents. Corm was extracted with petroleum ether, chloroform and methanol. Crude tannins were isolated from methanol extract. All extracts and crude tannins were evaluated for anthelmintic activity. Chloroform, methanol e...

The work reports antibacterial and antifungal activity of different solvent extracts of Origanum vulgare. The antimicrobial activity of methanol, chloroform and aqueous extracts were determined against nine different gram negative and gram positive bacterial strains and three fungal stains. The bacterial strains were Bacillus subtilis (ATCC 6633), Staphylococcus aureus (ATCC 29213), Micrococcus...
