| 摘 要： | 用水蒸气蒸馏法分别从陕西南部不同产地的茶叶中提取挥发油,利用气相色谱-质谱联用技术对挥发油中的化学成分进行分离和结构鉴定,运用气相色谱面积归一化法确定各个成分的相对百分含量。从南郑县茶叶挥发油中鉴出51种成分,从宁强县茶叶挥发油中鉴出47种成分,从西乡县茶叶挥发油中鉴出46种成分,各挥发油成分存在着一定的差异。对陕南不同产地茶叶的挥发油做了抗氧化试验,结果表明各挥发油对.OH均有明显的清除作用。

| Abstract: | The essential oil from tender leaves of Camellia sinensis in different area of the south area of Shannxi was extracted by steam distillation.The components were separated and structurally identified by gas chromatography/mass spectrometry,and the relative contents of the components by the peak-area normalization method adopted in gas chromatography.51 components were separated from the essential oil of the fresh leaves in Nanzheng county,47 components were identified from the essential oil of Ningqiang county,46 components were identified from the essential oil of Xixiang county and the compositions of those essential oils differed.Those essential oils were investigated by anti-oxidation activities,and they had obvious action to scavenging effect on ·OH. |
