目的:研究四方木叶挥发油成分。方法:采用GC-MS法对四方木叶挥发油成分进行分离和鉴定,并采用面积归一化法计算各组分的相对含量。结果:采用GC-MS分析共鉴出49个化合物,占挥发油总成分的81.38%,其中主要成分为:叶绿醇(12.75%);2,6,10-三甲基-2,6,10-十五碳三烯-14-酮或(金合欢基丙酮)(9.58%);6,10,14-三甲基-2-十五酮(5.70%);1-(3-羟基苯基)-乙酮(5.41%);(E)-4-(2,6,6-三甲基-1-环己烯-1-基)-3-丁烯-2-酮(5.26%);(E)-6,10-二甲基-5,9-十一碳二烯-2-酮(4.64%);5-戊基-1,3-苯二酚(4.21%);十六醛(2.73%);全反式或(E)-2,6,10,15,19,23-六甲基-2,6,10,14,18,22-二十四烷六烯(2.18%);去氢骆驼蓬碱(1.83%);1,8-萘内酰亚胺(1.72%)等。结论:初步了解了四方木叶的挥发油成分,为四方木叶的进一步开发利用提供了理论依据。
Objective: To study the constituents of essential oil Methods: GC-MS method was used to separate and identify the essential oil constituents from M. trifoliata, and the relative content of each component was calculated by area normalization method. Results: A total of 49 compounds were identified by GC-MS, accounting for 81.38% of the total volatile oil. The main components were: phytol (12.75%), 2,6,10-trimethyl- -pentadecatrien-14-one or (acacia acetone) (9.58%); 6,10,14-trimethyl-2- pentadecanone ) -ethanone (5.41%); (E) -4- (2,6,6-trimethyl- 1-cyclohexen- 1 -yl) -3-buten-2-one (E) -6,10-dimethyl-5,9-undecanadien-2-one (4.64%); (2.73%); all-trans or (E) -2,6,10,15,19,23-hexamethyl-2,6,10,14,18,22-tetracosahexaene (2.18% ); Harmful base (1.83%); 1,8-naphthalene imide (1.72%) and the like. Conclusion: The essential oil components of Sifangmu leaves were preliminarily understood, which provided the theoretical basis for the further development and utilization of Sifangsifu leaves.
