This study presents an attempt to evaluate the antioxidant potential and antimicrobial activity of methanolic extract, and essential oils prepared from the leaves of sage (Salvia officinalis L.). The content of polyphenol in the methanolic extracts from the leaves of Salvia officinalis was determined spectrophotometrically, calculated as gallic acid and catechin equivalent. The essential oils a...

background: medicinal plants (especially belong to lamiaceae family) are potential sources of new drugs to improve the treatment of diseases whose treatment is associated to anti-oxidative agents. in this paper, the ferric reducing ability of plasma (frap) activity of some lamiaceae and apiaceae species, has been evaluated. methods: aerial parts of the plants were dried, cut into small pieces a...

objectives this study was designed to determine the chemical composition, in vitro antioxidant activity, and total phenol content of various extracts of s. chloroleuca. materials and methods dried aerial parts of the plant were crushed, then sequentially extracted with n-hexane, ethyl acetate, and methanol. the fractions of s. chloroleuca were subjected to silica gel column chromatography and s...

BACKGROUND Antioxidants are of great importance for preventing oxidative stress that may cause several degenerative diseases. Studies have indicated phytochemicals have high free-radical scavenging activity, which helps to reduce the risk of chronic diseases. The aim of the present study is the determination of antioxidant properties, polyphenolic content and multidrug resistant bacteria of Sal...

Background: Homoeopathic mother tinctures and herbal extracts are used worldwide for medicinal purposes on the basis that the plant extract contains the active components essential for medicinal use. Quality analysis of samples ensures that the correct active components are present for medicinal use. Thin layer chromatography has been used extensively to determine the quality of plant extracts ...

The present work evaluated the effects of alcoholic extracts of salvia (Salvia officinalis), thyme (Thymus vulgaris), and 2 pure compounds (thymol and menthol) on the viability of Echinococcus granulosus protoscolices in vitro. Four different concentrations of each extract (2,500, 1,500, 1,000, and 500 µg/ml) and 3 different concentrations each of thymol and menthol (50, 10, and 1 µg/ml) were u...

Gemcitabine is an anti-cancer drug with clinically uses in the treatment of various neoplasms, including breast, ovarian, non-small cell lung, pancreaticand cervical cancers, T-cell malignancies, germ cell tumours, and hepatocellular carcinomas. However, it has also been reported to have many adverse effects. Naturally occurring anti-mutagenic effects, especially those of plant origin, have rec...

in the present study, an oxidative conversion of non-fluorescent dichlorofluoroscein (ldcf) to fluorescent dichlorofluoroscein (dcf) was used for detection of antioxidant properties of plant extracts. the rate of the reaction was followed by monitoring the formation of dcf as a function of time. the antioxidant assay was carried out for different concentrations of gallic acid, salvia mirzayanii...
