Commiphora species (from which myrrh is obtained) has been a source of several novel and bio-active natural compounds. Traditionally, Commiphora (Burseraceae) is used in southern Africa for the treatment of ulcers, fevers, and as a remedy for snake and scorpion bites. In western Africa, the macerated stem is used in the treatment of rheumatic conditions. The resin of some Commiphora species is ...

BACKGROUND/OBJECTIVE This study aims to measure the in vitro antioxidant capacity of Korean diet (KD) with American diet (AD) as a control group and to examine the ex vivo DNA damage reduction effect on human lymphocytes. MATERIALS/METHODS The KD applied in this study is the standard one-week meals for Koreans (2,000 kcal/day) suggested by 2010 Dietary Reference Intakes for Koreans. The AD, w...

BACKGROUND Betel quid chewing is a popular habit in Southeast Asia. It is believed that chewing betel quid could reduce stress, strengthen teeth and maintain oral hygiene. The aim of this study was to investigate the antioxidant and cytoprotective activities of each of the ingredients of betel quid and compared with betel quid itself (with and without calcium hydroxide). The correlation of thei...

Nineteen bisthiazoles were tested in order to assess their anti-inflammatory and antioxidant properties. First, we evaluated the in vitro direct antioxidant capacity of the bisthiazoles using the DPPH radical scavenging method. Then, the anti-inflammatory effect was tested in acute rat experimental inflammation by measuring the acute phase bone marrow response, the phagocytic capacity and the s...

Methods: The antioxidant potential of pyrrolo [1, 2-A] pyrazine-1, 4-dione, hexahydro-3-(2-methylpropyl) (diketopiperazine) extracted from Streptomyces sp. VITMK1 was studied using reducing power assay. The scavenging of 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical and nitric oxide (NO) radical by the compound was also studied. The cytotoxic activity of the compound on RAW 264.7 macrophage cel...

The air dried powdered plant materials were extracted with different organic solvents, screened for phytochemicals and analyzed for their biological activities. The antioxidant potential was evaluated by scavenging of DPPH radical, TPC and TFC, while antimicrobial activity by disc diffusion assay against a set of bacterial and fungal strains. Ethylacetate extracts showed higher free radical sca...

PURPOSE As a typical Chinese herbal medicine, Radix Glycyrrhizae (RG) possesses various pharmacological effects involved in antioxidant ability. However, its antioxidant has not been explored so far. The aim of the study was to investigate its antioxidant ability, then further discuss the antioxidant mechanism. METHODS RG was extracted by ethanol to obtain ethanolic extract of Radix Glycyrrhi...

The present study identifies the phytochemical profile of a hydroalcoholic extract derived from Smilax aspera leaves and stems, estimates its antioxidant capacity evaluates cytotoxic activity against glioblastoma (A172 cell line) rhabdomyosarcoma (TE671 line). Chemical analysis stems was performed with liquid chromatography combined quadrupole time-of-flight high-resolution mass spectrometry (L...

The aim of this study was to determine the best parameter for extracting phenolic-enriched kenaf (Hibiscus cannabinus L.) seeds by a pulsed ultrasonic-assisted extraction. The antioxidant activities of ultrasonic-assisted kenaf seed extracts (KSE) were determined by a 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity assay, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) ...

Biomolecules can be oxidized by free radicals. This oxidative damage has an important etiological role in aging and the development of diseases like cancer, atherosclerosis, and other inflammatory disorders. Synthetic antioxidants, like butylated hydroxyanisole, are good free radical scavengers, however, the synthetic antioxidants can be carcinogenic. Therefore, there is an increasing interest ...
