Analysis Of Volatile Components In Green Tea Grown In Wuxi Using Headspace Solid-Phase Micro-Extraction And Gc—Ms, Li Ming, Zeng Qian, Sun Peidong, Cao Guangqun
Food and Machinery
The volatile components in two typical cultivars of green tea grown in Wuxi, Baikhovi tea and Taihu tea, were extracted by headspace solid-phase micro-extraction (HS—SPME) and analyzed by GC—MS respectively. The results showed that there were 74 and 56 volatile components in the two cultivars, representing 98.59% and 98.51% of the total peak area. Alcohols, aldehydes, alkanes, esters, carboxylic acids and ketones were the major constituents, but their relative contents in the two cultivars were different. The contents of aldehydes, ketones and carboxylic acids in Baikhovi tea were higher but the contents of alcohols, esters and alkanes were lower than …
