results the isolates were completely resistant to the tested antibiotics, with minimum inhibitory concentration (mic) values for ceftazidime, imipenem, and gentamicin between 256 to > 256 μg/ml, 8 to > 256 μg/ml, and 64 to > 256 μg/ml, respectively. the r. dentatus extract had a broad spectrum activity against all tested isolates and maximum growth inhibition against isolates from burn wound an...

The present study investigates the antioxidant, anticancer, anticholinesterase, anti-genotoxic activities and phenolic contents of flower, fruit and seed methanol extracts of Hypericum retusum AUCHER. The amounts of protocatechuic acid, catechin, caffeic acid and syringic acid in methanol extracts were determined by HPLC. Total phenolic content of H. retusum seed extract was found more than fru...

Eichhornia crassipes (Mart.) Solms is a free-floating aquatic macrophyte growing normally to a height of 0.5 m to 1 m. This weed causes, substantial economic and ecological harm, warranting its removal, lest the impacts of the weed should become permanent. From an ecological perspective, the most effective, management approach is to make use of the weed for various purposes. The present study o...

Lentinus lepideus is an edible mushroom currently available in Korea. The acetone, methanol and hot water extracts were prepared and assayed for their antioxidant and antityrosinase inhibitory activities. The hot water extract showed the strongest β-carotene-linoleic acid inhibition compared to the other extracts. At 8 mg/mL, the methanolic extract showed a high reducing power of 1.21. The acet...

This study examines the antimicrobial activity of the hexane, dichloromethane and methanol extracts of Lippia multiflora and carvacrol isolated from the hexane extract. The result shows the hexane extract to be the most active, while the methanol extract exhibited no antimicrobial activity. The isolated carvacrol from the hexane fraction showed tremendous antimicrobial activity. These results c...

The aim of this study was to investigate in vitro antioxidant, anticholinesterase and antibacterial activities of the petroleum ether, chloroform and methanol extracts obtained from the aerial parts of Jurinea consanguinea DC. (Asteraceae). Total phenolic and flavonoid contents of these crude extracts were determined as pyrocatechol and quercetin equivalents, respectively. The methanol extract ...

α-amylase inhibitors are used in the treatment of type II diabetes mellitus. This study aims to identify the α-amylase inhibitors from two medicinal plants Mentha piperita and Annona squamosa. Primarily, the extract of both leaves was prepared using methanol and water and perform the screening of phytochemicals constituents present in the extract. Aqueous and methanol extract of mentha leaves c...

The plant Artemisia vulgaris is a perennial weed, belongs to the family Asteraceae, and locally known as Tarkha in Dir and Swat regions of Khyber Pakhtunkhwa (K.P.K), Pakistan. The present study aimed to evaluate the larvicidal activity of methanol extracts of roots, stem and leaves of Artemisia vulgaris against Culex quinquefasciatus. The 3 and 4 instars larvae of Culex quinquefasciatus were e...

background and objectives: salvia chloroleuca rech. f. & allen., is an endemic species growing wildly in north east and center parts of iran but there is no information about its safety. to provide information about the safety of the species, we evaluated its acute and sub chronic toxicity in rats. methods: in acute toxicity study, the aqueous methanol (80%) extract at a single dose of 2000...

background and objectives: datura innoxiamilleris one of the two species of datura (solanaceae) which grow in iran. there are many reports of the biological activities of datura and in the present study the ability of datura innoxia for inhibiting angiogenesis was evaluated. methods: the methanol extract and petroleum ether, chloroform and methanol fractions of datura innoxia flowers were obtai...
