Study on Antioxidant Activity of Volatile Components from Pu-erh Tea
摘要
Abstract
The change of aromatic components in Pu-erh tea during the pile-fermentation process were determined by SDE/GC-MS. The different volatile oils of Pu-erh tea were evaluated by DPPH and FRAP of antioxidant activity. The relationship between the antioxidant activity and the content of main volatile components were analyzed. The results showed that the contents of methoxybenzene compounds increased distinctively during the pile-fermentation process. Compared with the beginning of fermentation, the scavenging activities on DPPH radical and antioxidant activity by FRAP were increased gradually and improved by 100% and 296% respectively. The free-radical scavenging activities of DPPH radical and antioxidant activity by FRAP were highly correlated with the content of methoxybenzene compounds and linalool oxide compounds.关键词
