云南不同产地臭灵丹精油化学成分及抗菌活性

摘要/Abstract

摘要：

采用水蒸气蒸馏的方法，对采自云南4个不同地区（昆明，丽江，普洱，新平）的臭灵丹叶子进行挥发油提取，并利用GCMS和GCFID气相色谱联用技术分析其化学组成，分别从中鉴定出39、37、33、44个化合物。鉴定的化合物各占挥发油总量的9332% (昆明)、8057% (丽江)、9224% (普洱)和9385% (新平)。研究结果表明，采自这四个地区植物样品提取所得挥发油化学组成不尽相同：昆明产臭灵丹挥发油富含芳香族化合物(3806%)；而从丽江和普洱样品中获得的挥发油化学成分以倍半萜（分别为1989%和4465%）和氧化倍半萜（分别为4085%和3511%）为主；非氧化单萜和非氧化倍半萜化合物（分别为4223%和3325%）则是新平产臭灵丹挥发油的主要化合物类型。同时，对这些不同产地的臭灵丹挥发油也进行了抗菌活性测试。从以上实验研究结果推测环境差异是影响臭灵丹挥发油化学组成差异的重要因素，而不同的化学组成可能是导致4种样品抗菌敏感程度不同的原因。

Abstract:

Essential oils obtained by hydrodistillation from leaves of Laggera pterodonta collected from four different locations (Kunming, Lijiang, Puer and Xinping) in Yunnan, China, were analyzed using GCMS and GCFID. The number of compounds identified in each sample was 39, 37, 33 and 44, respectively, representing 9332% (Kunming), 8057% (Lijiang), 9224% (Puer) and 9385% (Xinping) of total essential oils. Chemical compositions of essential oils differed between sample locations: thus, those from Kunming were rich in benzenoid compounds (3806%) while those from Lijiang and Puer were largely dominated by sesquiterpenes (1989% and 4465% respectively) and sesquiterpenes oxide (4085% and 3511%, respectively), and those from Xinping contained a high proportion of monoterpene hydrocarbons and sesquiterpene hydrocarbons (4223% and 3325% respectively) (7548%). The results of tests on the antimicrobial activities of essential oils indicated that chemical composition was affected by environmental variation causing differences in sensitivity to microbes among samples.
