Objective: Prunus domestica is known for its nutritional values and therapeutic properties. It contains rich amount of natural phenolic phytochemicals such as phenolic acids, flavonoids and anthocyanin. Previous reports suggest that prune extract and juice inhibit peroxidation process. As no detailed antioxidant property, particularly on the whole fruit was studied, in this investigation, we no...

Background and Aims: This study aims to determine total phenolic, flavonoid contents in vitro biological activities of methanol (CEP-1), n-butanol (CEP-2), water (CEP-3), n-hexane (CEP-4) extracts obtained from Cephalaria procera. Methods: The phenolic content analysis, DPPH radical scavenging activities, cholinesterase, tyrosinase inhibitory properties the were evaluated using spectrophotometr...

In order to find new sources of natural antioxidants, the antioxidant capacities of 50 medicinal plants associated with treatment of rheumatic diseases were systemically evaluated using the ferric-reducing antioxidant power (FRAP) and Trolox equivalent antioxidant capacity (TEAC) assays, and their total phenolic contents were measured by the Folin-Ciocalteu method. Their antioxidant activities ...

Lily (Lilium) is used as an important edible and medical plant species with a vague taxonomic classification and a long history in China. Bulbs of six Lilium species (L. regale, L. concolor, L. pumilum, L. leucanthum, L. davidii var. unicolor and L. lancifolium) native to China were investigated with a view to their exploitation as a potential source of natural antioxidants due to their phenoli...

The contents and antioxidant ability of various classes of phenolic compounds present in the seeds of twenty soybean hybrids were evaluated. Total phenolics, tannins and proanthocyanidins were determined spectrophotometrically, after extraction of seeds with 70% aqueous acetone. In addition, the flavonoid contents were determined. The antioxidant activity of aqueous acetone extracts was evaluat...

OBJECTIVE The aim of this study was to investigate the antioxidant activity of extracts of various parts of Acanthopanax trifoliatus obtained by different extraction methods. The total phenolic and flavonoid contents of the extracts were also determined. MATERIALS AND METHODS The leaves, stems, stem bark, roots and root bark of A. trifoliatus were extracted separately using decoction, macerat...

In order to identify wild fruits possessing high nutraceutical potential, the antioxidant activities of 56 wild fruits from South China were systematically evaluated. The fat-soluble components were extracted with tetrahydrofuran, and the water-soluble ones were extracted with a 50:3.7:46.3 (v/v) methanol-acetic acid-water mixture. The antioxidant capacities of the extracts were evaluated using...

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...

Objective: The study was conducted to investigate the antibacterial and anthelmintic activities and to determine total phenolic contents of methanolic extract of Piper betel leaves. Materials and Methods: The extract was subjected to assay for antibacterial activity using both gram positive and gram negative bacterial strains through disc diffusion method; anthelmintic activity with the determi...
