Study on component analysis and in vitro functional effects of aroma components of Kuding tea

In order to clear the aroma components and in vitro functional activities of Kuding tea, by GC-MS analysis, DPPH free radical and hydroxyl radical assays, antimutagenicity test, AGS and HT-29 cancer cells proliferation inhibitory test, there were fifteen kinds of components were found in aroma components of Kuding tea, they were 2-imino-3-methyl-6-nitrobenzothiazoline, heptane, 2, 4-dimethyl-, decane, 2-ethylacridine, ergoline-8-carboxamide, 9, 10-didehydro-6-methyl-, (8.beta.) -, benzoic acid, methyl ester, 1-dimethyl the xylsilyloxyocta decane, benzothiazole, 2- (5-chloromethyl-1, 3, 4-oxadiazol-2-yl) -6-methoxy-;dimethyl phthalate, glycidol;propanamide, 8-dimethyl amino-1, 3, 7-trimethyl-3, 7-dihydropurine-2, 6-dione, phthalic acid, butyl undecyl ester, hexadecanoic acid, methyl ester and 2-amino-1- (o-methoxyphenyl) propane. And Kuding tea showed antioxidant, antimutagenicity test and anticancer effects. This study supplied the theoretical foundation for popularization of Kuding tea.
