present transplant study was carried out across lucknow, the capital of utter pardesh using two medicinally important plants viz., ?catharanthus roseus l.? and ?ocimum sanctum l.? to assess whether certain ecophysiological responses (change in total flavonoids and total phenolics) in these two plants may serve as the biomarkers of auto exhaust pollution. samples were taken from five different s...

ethanolic extract of leaves of elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, abts+ (2, 2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical scavenging and hydroxyl radical scavenging activities. the extract at 500 ?g/ml showed maximum iron chelating activity (76.70%) followed by the scavenging of the abts+ radical (55.77%) at the sa...

objective: there has been a growing interest in finding plants with biological active ingredients for medicinal application. materials and methods: three colors of petals of althaea officinalis (a. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. results: the reddish pink flowers of a. officinalis have more antioxidant...

background: satureja bachtiarica bunge, an endemic species with relatively wide distribution, is traditionally used as a medicinal and spice plant in iran. objective: essential oils composition, antioxidant activities and phenolics content of wild and cultivated s. bachtiarica of yazd origin were determined in this study. methods: hydrodistilled essential oils were analyzed by gc-fid and gc-ms....

background: although several studies have investigated the association between ovarian cancer risk and nonisoflavone flavonoids intake, these findings are inconsistent. this systematic review of published epidemiological studies was conducted to summarize and clarify the evidence on the association between ovarian cancer incidence and nonisoflavone flavonoids intake. materials and methods: pubm...

Radix Puerariae is the dried root of Pueraria lobata (Willd.) Ohwi, which releases a variety of isoflavones. The objective is to investigate the extraction process of total flavonoids in Radix Puerariae and to examine their effects on blood glucose MDA in alloxan-diabetic mice. Solvent extraction and column chromatographic isolation were used to extract the total flavonoids in Radix Puerariae, ...

Gastric cancer is the most common cancer among men in Korea, and dietary factors are closely associated with gastric cancer risk. We performed a case-control study using 334 cases and 334 matched controls aged 35-75 years. Significant associations were observed in total dietary flavonoids and their subclasses, with the exception of anthocyanidins and isoflavones (OR (95% CI): 0.49 (0.31-0.76), ...

Plant phenolics and flavonoids have a powerful biological activity, which outlines the necessity of their determination. The phenolics and flavonoids content of 20 medicinal plants were determined in the present investigation. The phenolic content was determined by using Folin-Ciocalteu assay. The total flavonoids were measured spectrophotometrically by using the aluminium chloride colorimetric...

OBJECTIVE To determine the antitumor activity of Radix tetrastigmae flavonoids and their inhibitory effect on regulatory T cells (Tregs) in mice. MATERIALS AND METHODS Total flavonoids were isolated from Radix tetrastigmae, the root of Tetrastigma hemsleyanum Diels et Gilg, and administered to C57BL/6 mice by oral gavage after inoculation with Lewis lung carcinoma (LLC) cells. The effects of ...
