柽柳实中挥发油和脂肪酸分析

首次研究了维药细穗柽柳(Tamarix leptostachys Bunge)实中挥发油和脂肪酸的化学成分。 分别采用药典中的挥发油提取法和索式取提法提取柽柳实中的挥发油和脂肪酸,使用气质联用技术获取总离子流图,各色谱峰相应的质谱图经过NIST2011标准谱库检索定性,并采用峰面积归一化法进行定量分析,计算各成分的相对百分含量。 两种方法分别鉴定出48种挥发油和19种脂肪酸。 挥发油主要成分为芳香类化合物(43.71%)、芳香性醛酮类(20.58%)、脂肪酸类(13.03%)、酯类(17.36%)和醇类(4.19%)等。 脂肪酸主要成分为棕榈酸(35.61%)、亚油酸(27.26%)和油酸(11.33%)等,其中不饱和脂肪酸含量占总脂肪酸含量的38.65%。 维药细穗柽柳实中富含丰富的挥发油和不饱和脂肪酸,具有很好的开发利用价值。

Analysis of Volatile Oils and Fatty Acids in Tamarix chinensis Fruit

The chemical compositions of volatile oil and fatty acid in Tamarix chinensis fruit were studied for the first time. Pharmacopoeia extraction and Soxhlet extraction methods were selected to separate the volatile oils and fatty acids. The extracts were analyzed by GC-MS technology. The matching rate between the results and standard NIST2011 spectra is over 80%. Fourty eight kinds of volatile oils and 19 kinds of fatty acids were identified. The main components of volatile oils include aromatic compounds (43.71%), aldehydes and ketones (20.58%), fatty acids (13.03%), esters (17.36%), alcohols (4.19%), etc. The main components of fatty acids include hexadecanoic acid (35.61%), linoleic acid (27.26%), oleic acid (11.33%), etc. The unsaturated fatty acid content is 38.65% in the total fatty acids. Tamarix chinensis fruit containing rich volatile oils and unsaturated fatty acids is preferable for potential utilization.
