this study was designed to examine bioactive compounds of the thyme-enriched corn oil and to determine the antioxidant activity of its methanolic extract. volatile compounds composition was investigated by gas chromatography-mass spectrometry (gc-ms), whereas phenolic compounds analysis was performed by reversed-phase high-performance liquid chromatography (rp-hplc). antioxidant activities of t...

Plants are almost reach sources of phenolic compounds such as flavonoids which are the most importantnatural antioxidants. Antioxidant compounds are essential for protecting human body against oxidativestress. However use elicitors could increase the antioxidant activity of plant. The purpose of this studywas to evaluate the effects of Chitosan on the content of phenolic and flavonoid compounds...

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...

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 effect of postharvest uv-c irradiation on phenolic compounds accumulation was investigated in berries of ‘rishbaba’ table grape (vitis vinifera cv. rishbaba). grape clusters were harvested at mature stage and irradiated with uv-c using fluorescent germicidal lamp (30 w, 90 cm) with a peak emission at 254 nm for 0 (control), 5 and 10 min. uv-c treatment had significant effect on individual p...

The total phenolic content of 13 commercially available fruit juices and juice drinks, selected to represent the most popular juice flavors in the United Kingdom, were analyzed using the Folin-Ciocalteu assay. Individual phenolic compounds were identified and quantified using HPLC-PDA-MS2. The catechin content and degree of polymerization of proanthocyanidins were also analyzed. Purple grape ju...

background scrophularia striata (scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. objectives antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from s. striata aerial parts was evaluated. materials and methods the antimicrobial activity of different extracts from s. stri...

recently, subcritical water extraction (swe) has been well known as a green technology for extraction of bioactive compounds from plants. in this study, subcritical water extraction, ultrasound assisted extraction (uae) and shaker solvent extraction (sse) were compared for extraction of phenolic compounds from fig (ficuscarica) pulp and skin. antioxidant activity of the extracts was evaluated u...
