摘要:
目的:分析沪产艾蒿鲜叶的挥发性成分,为艾蒿鲜叶的开发利用提供依据。方法:通过水蒸馏法提取艾蒿鲜叶挥发油,用气相色谱-质谱联用技术分析其化学成分。结果:从艾蒿鲜叶挥发油中鉴定了68个成分,主要为大香叶烯D(germacrene D)、桉叶素(cineole)、石竹烯(caryophyllenene)、侧柏酮(thujone),占总含量80%以上。结论:沪产艾蒿鲜叶含有的挥发油成分主要为大香叶烯D、桉叶素、石竹烯、侧柏酮,其中侧柏酮为艾蒿鲜叶的最主要成分,与干燥药材的挥发油成分有较大区别,在应用新鲜艾叶时应加以注意。

Abstract:
Objective :To analyze the chemical constituents of essential oil extracted from fresh leaves of Artemisia argyi cultivated in Shanghai,so that to provide valuable information for use of fresh leaves of Artemisia argyi. Methods : Hydrodistillation was employed to prepare essential oil from fresh leaves of Artemisia argyi cultivated in Shanghai,and GC-MS was used to analyze the constituents of the essential oil. Results :Fresh leaves of Artemisia argyi contains rich essential oil,and sixty-eight compounds were identified,the main constituents are D-germacrene,cineole,caryophyllenene and thujone. Conclusion :Essential oil from fresh leaves of Artemisia argyi have different chemical composition compared with the dried medicinal material.The main constituents are D-germacrene,cineole,caryophyllenene and thujone,and of which thujone is the richest.This is should be considered when use the fresh leaves of Artemisia argyi.
