中文摘要:
      采用水蒸气蒸馏法和气相色谱-质谱联用技术(GC-MS),比较原生百里香、金边百里香和阔叶百里香3种百里香精油的含油率、化学组成及其相对含量的差异。结果表明:精油含油率介于:1.50-4.82mL.kg-1,以阔叶百里香的精油含油率最高。3个百里香品种精油中共鉴定出59种化合物,包括23种萜烯类,13种醇类,7种酯类,4种酚类,4种酮类,5种烷烃类,2种醚类,2种醛类。原生百里香和阔叶百里香分别鉴定出34、35种化合物,百里香酚相对含量最高(37.45%和40.17%),归类为百里香酚型;金边百里香鉴定出29种化合物,顺式香叶醇相对含量最高(36.01%),归类为香叶醇型,具有浓郁的柠檬香气。不同百里香品种精油成分种类和含量存在明显差异,本研究可为泉州地区百里香的开发利用提供依据。
英文摘要:
      The content and the compositions of essential oil from three varieties of thyme(Thymus vulgaris、Thymus citriodorus、Thymus serpyllum)were analyzed and compared,by steamSdistillationextraction and GC-MS method.The results showed that :The oil content of essential oil is 0.15-5.00mL.kg-1,and the oil content of Thymus serpyllum is the highest.59 volatile components in the thyme were detected,including 23 Aerpenes, 13 Alcohols, 7 Esters, 4 Phenols, 4 ketones, 5 alkanes, 2 ethers and 2 aldehydes.34 and 35 compounds were identified in Thymus vulgaris and Thymus serpyllum respectively,the relative content of thymol was the highest (37.45% and 40.17%),It is classified as thymol type;29 compounds were identified from Thymus citriodorus,The relative content of cis-geraniol was the highest (36.01%),It is classified as geraniol type,and have a strong aroma of Lemon.There are significant differences in the types and contents of essential oil components among different thyme varieties,The study will provide proofs For the development and utilization of the three varieties of thyme in Quanzhou.
