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...

Plants of Euphorbiaceae are used to cure various diseases in traditional systems of medicine. For present study, Homonoia riparia, Kirganelia reticulata, Phyllanthus fraternus and Pedilanthus tithymaloides were selected on the basis of their availability and antimicrobial activity. Plant phenolics and flavonoids are known to possess antioxidant activity. Hence, it was decided to evaluate the an...

Ruta species are known as a potential source of natural products with biological activities. They are used in several fields such as in therapeutic and traditional medicine. In order to contribute to the valorization of these plants, this work investigated the chemical composition and antibacterial activity of the essential oils of Ruta montana and Ruta gravelons growing in tunisia (north o...

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...

nowadays, the use of natural antioxidants as alternative antioxidants is more acceptable than synthetic antioxidants mainly for negative effects such as carcinogenicity and toxicity. this has led to an increasing interest in the search for natural antioxidants. the objectives of this study were to measure total crude phenolic compounds and in sorghum grain as natural antioxidant sources, to det...

This study examined if pre-germination altered the water content and water activity, contents of phytate, total phenolic, (±)-catechin, quercetin and total antioxidant capacity of almond  (Prunus dulcis)kernel. Raw almond kernels were submerged for 15 hours in water, 0.02 mol dm-3 phosphate buffer solution (pH 5.0) and 0.02 mol dm-3 phosphate buffer solution (pH 7.0) at 25 and 40ºC, respectivel...

in the present study, we have reported the total phenolic content, total flavonoid content, antioxidant and antimicrobial activity of aerial parts of salvia leriifolia extracts and fractions. methanolic, n-hexane, chloroform, and ethyl acetate extracts were screened to analysis their antioxidant activities by four complementary test systems, namely dpph free radical scavenging activity (rsa), t...

PURPOSE Gardenia jasminoides is a traditional medicinal plant rich in anti-inflammatory flavonoids and phenolic compounds and used for the treatment of inflammatory diseases and pain. In this present study, antioxidant potential of Gardenia jasminoides leaves extract was evaluated by using various antioxidant assays. METHODS Various antioxidant assays such as 1, 1-diphenyl-2-picrylhydrazyl (D...

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 this study it was aimed to investigate inducibility of secondary metabolism in Astragalus chrysochlorus by yeast extract which is known to cause the synthesis of defensive phenolic metabolites. Cell suspension cultures of Astragalus chrysochlorus responded to elicitor treatment (10 gl(-1) yeast extract) by increasing phenylalanine ammonia lyase (PAL E.C. 4.3.1.5) activity the key enzyme of p...
