2,2'-DIPHENYL-1-PICRYLHYDRAZYL RADICAL- SCAVENGING ACTIVITY OF DIFFERENT Teucrium montanum L. EXTRACTS
The sequential extraction of Teucrium montanum L. was realized with five solvents of different polarities (70% methanol, petroleum ether, chloroform, ethyl acetate, n-butanol). The scavenging activity (SA) of obtained extracts was tested by measuring their ability to scavenge stable 2,2`-diphenyl-1-picrylhydrazyl (DPPH) free radical using electron spin resonance (ESR) spectroscopy. The results ...
متن کاملAnalysis of Antioxidant in Curcuma Angustifolia Rhizome by 2,2-diphenyl-1-picrylhydrazyl (dpph) Method
Curcuma angustifolia also known as ‘haledo’ is commonly found in Sikkim and has many medicinal uses and has been used traditionally since ancient ages. Its rhizome is aromatic and the solvent extract of the rhizome has free radical scavenging activity which was carried out in this study by 2,2-diphenyl-1-picrylhydrazyl DPPH. Hot methanol extract and cold methanol extract of the dried powder of ...
متن کامل2,2-Diphenyl-1-picrylhydrazyl as a screening tool for recombinant monoterpene biosynthesis
BACKGROUND Monoterpenes are a class of natural C10 compounds with a range of potential applications including use as fuel additives, fragrances, and chemical feedstocks. Biosynthesis of monoterpenes in heterologous systems is yet to reach commercially-viable levels, and therefore is the subject of strain engineering and fermentation optimization studies. Detection of monoterpenes typically reli...
متن کاملChemical studies on antioxidant mechanism of tea catechins: analysis of radical reaction products of catechin and epicatechin with 2,2-diphenyl-1-picrylhydrazyl.
Tea catechins, an important class of polyphenols, have been shown to have wide spectrum of antitumor activity believed to be due mainly to their antioxidative effect. In this study, the radical scavenging behavior of catechins on 2,2-diphenyl-1-picrylhydrazyl (DPPH) was studied. Two reaction products of (+)-catechin, and two reaction products of (-)-epicatechin were purified and identified. The...
