AIMS The main aims of the study were to evaluate the phytochemical constituents and to study the antioxidant, antimicrobial, antidiabetic, anti-inflammatory, and analgesic activities of extracts from stem wood of Pterocarpus marsupium. MATERIALS AND METHODS Ethanol, acetone and isopropyl alcohol (IPA) (1:1) extracts of stem wood of P. marsupium were subjected to phytochemical screening and an...

The acetone extract of the lichen Ramalina farinacea and its (+)-usnic acid constituent showed antimicrobial activity against Bacillus subtilis, Listeria monocytogenes, Proteus vulgaris, Staphylococcus aureus, Streptococcus faecalis, Yersinia enterocolitica, Candida albicans, and Candida glabrata. Norstictic acid was active against Aeromonas hydrophila as well as the above microorganisms except...

Plants collected from Limpopo province of South Africa were investigated for their antioxidative potential using the DPPH radical scavenging assay. Acetone extracts of Flueggea virosa had the highest antioxidant activity with an IC₅₀ value of 30 µg/ml, closely matching the ascorbic acid with an IC₅₀ value of 25 µg/ml. The lowest antioxidant readings were observed with extracts of Rhynchosia ven...

Insecticidal and antifeedant activities of acetone extract of Casimiroa edulis (Rutaceae) leaf were screened against 4 instar larvae of Spodoptera littoralis. Crude extract had LC50 value of 79.47μg/cm and SC50 of 88.97 μg/cm. Seven fractions were then collected from the extract by silica gel column chromatography (eluted by different solvent systems). Four of these fractions recorded percent s...

Herbal teas are widely consumed in Turkey. This study aimed to evaluate the antimicrobial activity of methanol, acetone, and aqueous extracts endemic Sideritis galatica plant collected from Afyonkarahisar. For this purpose, effect different concentrations (2.5%, 5%, 10%, 20%) these on L. monocytogenes, B. cereus, S. aureus, E. faecalis, coli, coli O157, typhimurium, C. albicans were investigate...

Ten plant species were collected from the Nelspruit Botanical Garden based on their uses by traditional healers in Limpopo Province of South Africa. Hexane, dichloromethane (DCM), acetone and methanolic extracts of this plants were screened for antibacterial activity against Staphylococcus aureus ATCC 29213, Pseudomonas aeruginosa ATCC 27853, Enterococcus faecalis ATCC 29212 and Escherichiacoli...

Purpose: The purpose of the study is to evaluate the antimicrobial and antitumor activities of Stevia rebaudiana (Asteraceae) leaf extracts. Methods: Four solvent extracts (ethyl acetate, acetone, chloroform and water) of Stevia rebaudiana leaves were investigated against Staphylococcus aureus, Salmonella typhi, Escherichia coli, Bacillus subtilis, Aeromonas hydrophila and Vibrio cholerae by us...

Antioxidant and antimicrobial effects, total phenolic content and flavonoid concentrations of methanolic, acetone and ethyl acetate extracts from Xeranthemum annuum L. were investigated in this study. The total phenolic content was determined using Folin-Ciocalteu reagent and ranged between 101.33 to 159.48 mg GA/g. The concentration of flavonoids in various X.annuum extracts was determined usi...

Cervical cancer is among the most prevalent forms of cancer in women worldwide. Diospyros lycioides was extracted using hexane, ethyl acetate, acetone, and methanol and finger print profiles were determined. The leaf material was tested for the presence of flavonoids, tannins, saponins, terpenoids, and cardiac glycosides using standard chemical methods and the presence of flavonoids and phenoli...

IN a series of papers [Chibnall and Channon, 1927, 1, 2, 3; Channon and Chibnall, 1927], we have recorded certain results which we have obtained in the analysis of the ether extract of the leaf-cell cytoplasm of the cabbage. The object of the present paper is to discuss these results so far as is at present possible from their chemical and physiological aspects, and, in passing, to refer to our...
