The aim of this research were to determine antioxidant activity from different polarities beans extracts of five legumes beans using two methods of antioxidant testing which were DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2’azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) and correlation of total phenolic, flavonoid and carotenoid content in various extracts of five legumes beans with th...

BACKGROUND Many medicinal plants from the Lamiaceae family can be easily found in Algeria. These plants have been used as traditional medicines by local ethnic groups. Thymus capitatus is known in Algeria as "Zaatar" and has been commonly used as a spice, and reported to have many biological effects. OBJECTIVES This paper focused on the assessment of the antioxidant potential and antifungal a...

Recent research shows variations in pollen chemical constituents and, consequently, in their therapeutic properties. Mono and multifloral bee pollen extracts were investigated for antioxidant and enzyme inhibitory activity properties, phenolic compounds and fatty acid composition. Generally, Eucalyptus spp. and multifloral extracts exhibited potent inhibitory activity against α-amylase, acetylc...

In this research work, a series of heterocyclic Schiff base compounds bearing arylsulfonyl ester moiety (2a-i) were designed, synthesized, characterized by spectral techniques such as 1D NMR (1H and 13C), 2D (COSY HMQC), FT-IR; then examined their antioxidant activity was using four different methods DPPH, ABTS, CUPRAC, ?-carotenelinoleic acid assays. According to the results obtained, it deter...

Tulsi is known as “Queen of plants” “The mother medicine of nature”. Tulsi i.e. Ocimum sanctum is a plant with enormous properties for curing and prev...

In 1996-2004 a case-control study on nutrient intake, dietary constituents and risk of squamous cell carcinoma of the esophagus was conducted in Montevideo, Uruguay. In fact, Uruguay, and especially its northern provinces, which border Brazil, are high-risk areas. The study included 234 cases and 936 controls. The controls were hospitalized patients with non-neoplastic disease, which was not re...

Some species of Vicia genus (Papilionaceae) are used in traditional medicine. In the present study, free radical scavenging and antioxidant activity of aerial parts of V. sojakii were investigated in six different models. IC50 for DPPH radical-scavenging activity was 440.4 ± 13.2 mg mL -1. It showed good nitric oxidescavenging activity between 0.2 and 1.6 mg ml-1. Extract showed very potent Fe2...

Background: This study aimed at investigation of the chemical composition, antimicrobial activity, and antioxidant properties of clove, cumin, origanum, and anise Essential Oils (EOs). Methods: Chemical compositions of the EOs were identified using Gas Chromatography/Mass Spectrometry (GC/MS). The antibacterial activities of EOs against four important food-borne bacteria were assessed by disc ...

the present study explores the chemical constitution and antioxidant activity of the essential oils of the aerial parts of artemisia dracunculus l. and the flower heads of matricaria chamomilla l. gc-ms analysis revealed the presence of (z)-anethole (51.72%), (z)-β-ocimene (8.32%), methyleugenol (8.06%), limonene (4.94%) and linalool (4.41%) in artemisia dracunculus and (e)-β-farnesene (24.19%)...

The antioxidant capability, total phenol, total flavonoid, anthocyanins, ascorbic acid contents, and reducing power contents of polar and non-polar extracts for flower and leaves in two stages of growth for Rhamnus kurdica Boiss in flowering were evaluated in this work. The polar extraction of flower of R. kurdica Boiss had a higher total phenolic content as well as antioxidant activity compare...
