新疆紫花苜蓿挥发油化学成分的分析

Analysis of Volatile Oils in Alfalfa of Xinjiang

摘要: 采用水蒸气蒸馏法提取新疆紫花苜蓿中的挥发油，通过气相色谱-质谱联用技术，结合计算机质谱图库检索，对分离的化合物进行结构分析。从紫花苜蓿挥发油中初步确定了53种化合物，占挥发性物质含量的95.6%，并用峰面积归一化法得出各化学成分在挥发油中的含量。紫花苜蓿挥发油主要组分为6,10,14-三甲基-2-十五酮（10.28%）、叶绿醇（8.23%）、反-2-烯基-己醛(5.46%)、3-甲基丁醛(3.61%)和沉香醇（3.17%）等。

Abstract: The chemical components of volatile oils from Xinjiang Alfalfa were collected by steam distillation and were analyzed by GC／MS. 53 components are identified, which account for over 95.6% of the volatile oil by normalization method. The main components are 6,10,14-trimethyl-2-pentadecanone(10.28%), phytol (8.23%), (E)-2-hexenal（5.46%）, 3-methylbutanal (3.61%) and linalool（3.17%）,etc.
