Tecoma stans (Bignoniaceae) is used in the treatment of diabetes, stomach pains, rheumatism, diuretic, vermifuge and tonic in traditional medicine. The present study has been design to evaluate antinociceptive and anti-inflammatory activities of alcohol and aqueous extracts of Tecoma stans leaves and to determine total phenolic and flavonoid contents. Both extracts shows dose dependent activity...

?-Amylase inhibitory activities of ethanol extracts from six selected Iranian Salvia species (S. hydrangea DC., S. hypoleuca Benth., S. officinalis L., S. reuterana Boiss., S. verticillata L. and S. virgata Jacq.) were examined, using in vitro model. In addition, antioxidant capacities (DPPH• radical scavenging) and total flavonoid cotents of the extracts were also determined. The results showe...

The authors investigated the in vitro antioxidant properties of nine selected flavonoid aglycons, namely quercetin, kaempferol, myricetin, apigenin, luteolin, daidzein, genistein, formononetin and biochanin A. The in vitro antioxidant power of flavonoids basically depends on their chemical structure. The concentration of those flavonoids in vegetables and fruits frequently consumed in Hungary w...

Extending research on the protective effect of flavonoids in cell culture and animal studies, we examined the association between consumption of flavonoids and flavonoid-rich foods and development of exocrine pancreatic cancer within the alpha-Tocopherol, beta-Carotene Cancer Prevention Study cohort. Of the 27,111 healthy male smokers (50-69 years) who completed a self-administered dietary ques...

A rapid method has been developed for the quantitative estimation of β-sitosterol, total phenolic and flavonoid compounds present in the leaves of Moringa oleifera Lam. (Family: Moringaceae). The hydroalcoholic extract of the leaves was subjected for the quantitative estimation of these compounds. The hydroalcoholic extract of the leaves of Moringa oleifera was prepared by the process of cold m...

The total phenolic and flavonoid content of extracts from peel of kumquat were higher than those from pulp, and those extracted from immature kumquat were higher than those from mature kumquat. The highest levels of phenolic and flavonoid content were obtained in hot water extracts. The flavonoids of kumquat extracted from hot water were mainly soluble conjugated compounds, including C-glycosid...

The antiviral activity of total flavonoid extracts from Selaginella moellendorffii Hieron and its main constituents amentoflavone were investigated against coxsackie virus B3 (CVB3). When added during or after viral infection, the extracts and amentoflavone prevented the cytopathic effect (CPE) of CVB3, as demonstrated in a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) col...

Acalypha indica, a known medicinal plant in the treatment of various degenerative diseases and a potential source of valuable bioactives. The present study investigates the total phenolic and flavonoid content and also screen for phytocompounds in A. indica leaf extract obtained by two extraction methods, comparatively. Results indicated that the maceration extraction method (MEM) had highest t...
