dpph radical-scavenging activity of the bene hull oil (bho), sesame oil (seo), rice bran oil (rbo), the oils' methanolic (ch3oh/h2o, 80:20 v/v) or hexane extracts, and their unsaponifiable matters fraction were measured and compared with each other. as a radical-scavenger, seo was significantly stronger than rbo and bho, respectively. unlike bho and rbo, the unsaponifiable (usm) fraction of the...

Degenerative diseases can be caused by free radicals, whereas antioxidants overcome radicals. Kedondong leaves (Spondias dulcis Parkinson) and soursop (Annona muricata Linn.) are potential sources of suitable antioxidant compounds. This study aims to determine the activity relationship between total phenolics from combination S. A. leaf extracts. leaves, were macerated with 96% ethanol then for...

an aqueous extract of pimpinella anisum was used for green synthesis of silver nanoparticles by bio reduction of an aqueous solution of silver nitrate. silver nanoparticles were characterized by uv–vis spectrometry, fourier transform infrared spectroscopy (ftir), x-ray diffraction (xrd) analysis, scanning electron microscopy (sem) and energy-dispersive x-ray analysis (edax). the increase in abs...

objective: the aim of the present study was to elucidate the possible biochemical improving effect in lipid metabolic that may result from continuous treatment with green tea extract in normal albino rats and those rendered hyperlipidemic by long term supplementation of fat-enriched diet. materials and methods: fifty male albino rats aged six weeks with 200±10 g weight were randomly divided int...

BACKGROUND Extracts of plants have been considered as sources of natural antioxidant agents. In this study, we aimed to explore the antioxidant capacity of the aqueous root extract of Asparagus cochinchinensis (Lour.) Merr. METHODS Using vitamin C (Vc) as a positive control, we analyzed the aqueous root extract of A. cochinchinensis free radical scavenging ability in vitro. We also establishe...

Introduction: Rosa damascena mill L., well-known as Rose, has numerous pharmacological properties including antioxidant, antitussive, relaxant effect on tracheal chains, hypnotic, antibacterial and anti-HIV. Objective: The objective of the present study was to evaluate antioxidant and free radical scavenging activity of various extracts of Rose flower petals. Methods: Chloroform, acetone, ethan...

Herbs are vital sources of bioactive compounds. This study evaluates the antimalarial, antioxidant, phytochemical and nutritional properties Gongronema latifolium Benth. (Uteze) leaves. Pulverized dry leaves sample were macerated in hexane, methanol, ethanol distilled water to obtain their respective extracts. The antimalarial efficacy these extracts was assessed male Swiss albino mice infected...

Temu blenyeh (Curcuma purpurascens Bl) is a species of curcuma that still rarely studied. thought to have antioxidant activity so it can reduce free radical activity. The purpose this study was screen phytochemicals and determine the temu extract using 2,2-Diphenyl-2-picrylhydrazyl (DPPH) method. macerated with 96% ethanol solvent, then its tested method at maximum wavelength 515.8 nm vitamin C...

In the present study, ethanol and aqueous extracts of leaf galls of Cinnamomum verum were prepared to evaluate the antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl free radical scavenging assay and superoxide radical scavenging assay with ascorbic acid as a standard, and analgesic activity by tail immersion test and acetic acid-induced writhing test methods using diclofenac sodium as th...
