SPME-GC/MS 联用分析六堡茶茶花香气成分
HS-SPME/GC-MS analysis of the aroma components from flower buds of Liubao tea plant
摘要
Abstract
The tea plant flowers of indigenous species in Liubao, Guangxi were characteristic with long florescence, high yield and rich fragrance, but its chemical composition has not been reported for the development and utilization of flower resource. The aroma components in flower buds of three kinds of tea plants, Dayezhong, Zhongyezhong and Xiaoyezhong were analyzed by HS-SPME/GC-MS. The relative contents of the chemical constituents were determined by area normali-zation method. Totally 37, 32 and 45 aroma compounds were identified from Dayezhong, Zhongyezhong and Xiaoyezhon-gin Liubaowhich accounted for 99. 75 %, 99. 02% and 99. 45% of the total aroma components, respectively. The main constituents in the Dayezhong were Acetophenone, 4-Methyl-1,5-Heptadiene, Benzoic acid, methyl ester, Guaia-3,9-diene, cis-Linaloloxide, Cedarene,Methyl salicylate, d-Cadinene, 1-amino-Cyclopentanemethanol,In the Zhongyezhong were Acetophenone,Perillene,(1S)-(+)-3-Carene,(+)-α-Elemene,Benzoic acid ethyl ester,Seychellene,α-Copaene, Neoclovene,Ylangene,cis-Linaloloxideand acetophenone,Perillene,Ocimene,(+)-α-Elemene, 2-isopropyl-5-methyl-9-methylene-(+)-α-ElemenBicyclo[4.4.0]dec-1-ene, Cubenol,α-Acoradiene,α-Bisabolene,Ylangene,Benzoic acidethyl ester in the Xiaoyezhong. Acetophenone was the characteristic compounds among the three kinds of tea plants which con-stituted their unique aroma along with other components. The study provides scientific support for exploitation and utiliza-tion of flowers buds of the tea plants.关键词
