Free-Radical-Scavenging Activity of Various Components in Terminalia Chebula Ritz
摘要
Abstract
In this experiment the free radical-scavenging activity of various components from terminalia chebula ritz was studied The results showed that all extracts of terminalia chebula ritz stems had strong DPPH- scavenging effects. The activity-decreased sequence of the extracts by different extracting regents was: methanol>ethyl acetate>acetone>ether>petro-ether. The methanol extract (1mg/mL) had better activity than that of TBHQ. The activities of the component A was 1.6 folds higher than the original. The chromatographically purified component C showed the strongest activity among all samples. Its activity was a little stronger than that of tea polyphenol, as 1.2 folds higher than that of TBHQ. By color test, UV-Vis and H1 NMR analysis, all of the purified components were confirmed to be the derivatives of myrobalani-tannin or their hydrolyzed segments.关键词
