基于UHPLC-Q-TOF/MS的不同产地普洱生茶化学成分差异研究
Study on the Chemical Constituents of Pu-erh Teas from Different Areas by UHPLC-Q-TOF/MS
摘要
Abstract
In order to fully understand the influences of the production area on pu-erh raw tea quality and chemical composition, 12 pu-erh raw tea samples were selected from different mountains (villages) in Lincang, Pu'er, and Xishuangbanna. The nonvolatile tea metabolite phenotypes of the pu-erh raw teas were analyzed by ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry-four (UHPLC-Q-TOF/MS). The results showed that the pu-erh raw teas from different areas had distinct chemical compositions. Pu-erh raw teas from Xishuangbanna (including Mengla, Menghai, and Jinghong), Pu'er, and Lincang could be seperated by principal component analysis. Pu-erh raw teas could also be seperated according to producing areas (southeast, southwest, and northwest of pu-erh tea area). Seventy nine main components in pu-erh raw teas were identified, and the relationships between the components and the taste qualities of the 12 pu-erh raw teas were also analyzed. This study showed that the metabolite phenotypes analyzed by UHPLC-Q-TOF/MS could be used for the discrimination of pu-erh raw teas according to producing areas.关键词
