Background: Woodfordia fruticosa is used traditionally as antidysenteric compound for fodder animals. Stem and flower extracts are previously flourished for their antibacterial activity. Leaves are also equally important, which are preliminary screened for their bioactive components in present study. Objective: Evaluation of antibacterial activity of leaves of W. fruticosa and detection of the...

The aim of this research was to extract phenolic compounds from defatted Roselle (Hibiscus sabdariffa L.) seed and assess their antioxidant potential. Water, ethanol (30%), methanol (30%) and acetone (30%) were used as solvent for extraction. The proximate composition, total phenolic content and extraction yield were analyzed. Antioxidant efficacies of Roselle seed extract were tested by using ...

BACKGROUND The current trend globally is the utilization of natural products as therapeutic agents given its minimum side effects. The leaves of Stevia contain several active ingredient compounds such as rebaudioside. Stevia extract have been used for many purposes. Active oxygen radicals can induce base modifications, DNA breakage, and intracellular protein crosslink's. This study was done to ...

We assayed the antimicrobial activity of acetone and aqueous extracts of the stem bark of Sclerocarya birrea on some selected bacteria and fungi species including; Streptococcus pyogenes, Plesiomonas shigelloides, Aeromonas hydrophila, Salmonella typhimurium, Cryptococcus neoformans, Candida glabrata, Trichosporon mucoides, and Candida krusei using both agar well diffusion and minimum inhibitor...

In the present study various extracts of Cyperus esculentus L. such as acetone, 50% ethanol, chloroform and petroleum ether were evaluated for their antibacterial activity against several human pathogens such as Escherichia coli, Staphylococcus aureus, Salmonella sp, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa and Citrobacter freundii, by using disc diffusion method. The act...

Cellular damage caused by reactive oxygen species has been implicated in several diseases, thus establishing a significant role for antioxidants in maintaining human health. Acetone, methanol, and hot water extracts of Pleurotus citrinopileatus were evaluated for their antioxidant activities against β-carotene-linoleic acid and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals, reducing power, ferr...

Citrus limonoids have shown to inhibit the growth of cancer in colon, lung, mouth, stomach and breast in animal and cell culture studies. For the first time in the present study, an attempt has been made to isolate antioxidant fractions and five limonoids from red Mexican grapefruit seeds. Defatted seed powder was successively extracted with hexane, ethyl acetate (EtOAc), acetone, methanol (MeO...

OBJECTIVES The leaf and bark of Thevetia peruviana (Family: Apocynaceae) plant was administered for 24 h to the freshwater fish Catla catla (Hamilton) to evaluate their piscicidal activity in laboratory and cemented pond condition. MATERIALS AND METHODS AND RESULTS The LC0 values of lef and bark extracts of different solvents (i.e., acetone, diethyl ether, ethyl alcohol, chloroform and carbon...

Background: In Nigeria, the leaves of Manihot esculenta (Crantz) are eaten as vegetables. The leaves are rich in phytochemicals, valuable and natural sources of antioxidants, and are highly useful for human health and disease prevention. This study was aimed to evaluate the in vitro inhibitory effects of two extracts derived from the plant leaves on α-glucosidase and α-amylase. The total flavon...

in the present study, plumbago zeylanica linn. (plumbaginaceae) , one of the folk medicinal plants commonly used as antifertility agent was evaluated for its antifertility effect. five successive solvent extracts, petroleum ether, chloroform, acetone, ethanol and water extracts, of the stems of p. zeylanica were studied on estrous cycle at two dose levels, 200 and 400 mg/kg respectively.   of t...
