摘要
Abstract
In order to explore the quality differences between ancient tree and arborous Pu'er tea in Xishuangbanna area,Liquid chromatograph and HS-SPME-GC-MS technology were used to detect and analyze the catechatin components and aroma composition of tea samples.The detection results of catechin components showed that principal component analysis could effectively distinguish between Bulang ancient tree,Bulang arbor,Yi Wu ancient tree and Yi Wu arbor.The detection results of HS-SPME-GC-MS showed that 138 kinds of aroma substances were detected in four groups of tea samples,among which 9 kinds of aroma substances including n-octanol,geraniol,1-octen-3-ol,β-ionone,β-ionone,methyl salicylate,right-handed terpenoid diene,decamethylcyclopentasiloxane and tetradecamethyl cycloheptasiloxane can be used as the basis to distinguish the four groups of tea samples.The results of Relative Odor Activity Value(ROVA)analysis indicated that there were four common key aroma substances in arborous Pu'er tea;There was no obvious rule in the key and modified aroma substances of ancient tree Pu'er tea between groups or within groups.关键词
