摘要

采用同步蒸馏提取的方法获得了23个优质茶叶品种花中的挥发物，并利用气相色谱-质谱联用技术鉴定了79种芳香成分。检测到的主要成分有苯乙酮、芳樟醇、1-己醇、2-戊醇、水杨酸甲酯、4-甲基-2-己酮、-甲基苯甲醇、顺式芳樟醇、乙酸、z -3-己烯-1-醇、s- 2-庚醇和己醛。各品种均检测到苯乙酮和芳樟醇，各挥发物含量均在20%以上。分析的几个品种含有一些其他品种未检出的特殊成分。

Characterization of the key aromatic constituents in tea flowers of elite Chinese tea cultivars

The volatiles in flowers of twenty-three elite tea cultivars were obtained by simultaneous distillation extraction, from which seventy-nine aromatic constituents were identified using gas chromatography coupled with mass spectrometry. The major detected constituents found were acetophenone, linalool, 1-hexanol, 2-pentanol, methyl salicylate, 4-methyl-2-hexanone, alpha-methyl-benzene methanol, cis-linaloloxide, acetic acid, Z-3-Hexen-1-ol, S-2-heptanol, and hexanal. Both acetophenone and linalool were determined from every cultivar, and each volatile accounted for more than 20 % of the total. Several of the cultivars analysed contained some special constituents which were not detected from other cultivars.
