Abstract

The essential oils from aerial parts of young (sample A) and mature leaves (sample B), fruit (sample C), and flowers (sample D) of Zanthoxylum hyemale were obtained by hydrodistillation and analyzed by GC, GC/MS, and chiral phase gas chromatography (CPGC). Thirty-four compounds were identified from the essential oils, representing approximately 90.71, 91.19, 87.33, and 89.08 % of the oils, respectively. The major constituent of the young leaf essential oil was the sesquiterpene trans-nerolidol (51 %), while the main constituent of mature leaf (31 %) and flower oils (22 %) was an as yet unknown humulane-type sesquiterpenoid, which was characterized by spectral techniques (EI-MS and 1D-, 2D-NMR) as 3,7,10,10-tetramethylcycloundeca-3,7-dien-1-ol ( 1) and given the trivial name "hyemalol". In the fruit essential oil, the most abundant components were the monoterpenes beta-pinene (25 %) and alpha-pinene (10 %). The antimicrobial activity of the essential oils and some isolated compounds is also reported.

摘要

通过水蒸馏法从竹叶椒幼嫩地上部分（样品A）、成熟叶片（样品B）、果实（样品C）和花朵（样品D）中提取挥发油，并采用气相色谱（GC）、气相色谱 - 质谱联用（GC/MS）和手性相气相色谱（CPGC）进行分析。从挥发油中鉴定出34种化合物，分别约占挥发油的90.71%、91.19%、87.33%和89.08%。幼嫩叶片挥发油的主要成分是倍半萜反式橙花叔醇（51%），而成熟叶片（31%）和花朵挥发油（22%）的主要成分是一种尚未明确的葎草烷型倍半萜类化合物，通过光谱技术（电子轰击质谱和一维、二维核磁共振）鉴定为3,7,10,10 - 四甲基环十一碳 - 3,7 - 二烯 - 1 - 醇（1），并赋予俗名“hyemalol”。在果实挥发油中，含量最丰富的成分是单萜β - 蒎烯（25%）和α - 蒎烯（10%）。还报道了挥发油和一些分离化合物的抗菌活性。
