The sensory quality of the samples w evaluated and the biochemical components were tested. The results show that the white tea of Rucheng white tea white tea is full of white hair and buds, and the soup is apricot yellow, bri fragrant, slightly rich, fresh and fresh, and the bottom of the leaf is tender, complete and red ontents of water extract, tea polyphenol, free amino acid, caffeine and catechin were 42.42% 36.86%,3.66%,4.58% and 11.92%, respectively. The aroma components were detected in 45 components. The main aroma components were Methylis salicylas, methyl methylene, geraniol, beta linalool, anti-3, 7-two methyl-2, 6-butadienic, beta arrosterone, orange TERT alcohol, 1-ethyl-2- formyl pyrrole, 3, 5-octadiene- ketone, camphor oxide(furano), and linalool oxide.
