摘要
[目的]研究藏药曲玛孜2种基原植物西伯利亚蓼和小大黄挥发油的化学组成。[方法]采用水蒸气蒸馏法和气相色谱-质谱( GC-MS)联用技术鉴定藏药曲玛孜挥发油化学成分。[结果]从藏药西伯利亚蓼挥发油中共鉴定19个成分,包括萜类、芳香化合物、脂肪烃类等,其中主要含有植醇(35.81%)、植酮(13.28%)、萘(4.79%)、亚麻酸甲酯(3.46%);藏药小大黄挥发油的主要成分为(Z,E)-2,13-十八烷二烯-1-醇(29.99%)、大黄酚(15.18%)、萘(13.98%)、棕榈酸(7.00%),结构类型涉及脂肪醇类、蒽醌类、萜类等29个成分。[结论]藏药曲玛孜2种基原植物西伯利亚蓼和小大黄挥发油中主要成分组成相差较大,该研究为揭示曲玛孜品种整理、资源保护和合理利用提供一定的化学基础。
Abstract
Objective] To study chemical composition of the essential oil of Tibetan medicine Qumazi.[ Method] Essential oil of Tibetan medi-cine Qumazi was identified by using water vapor distillation and GC-MS.[Result]The major components of Polygonum sibiricum, involving ter-penes, aromatic compounds and aliphatic hydrocarbons, were phytol (35.81%), phytone (13.28%), naphthalene (4.79%),methyl linole-nate (3.46%).Meanwhile, the essential oil of Rheum pumilum was mainly including in fatty alcohols, anthraquinones, terpenes and the main volatile components of Rheum pumilum were Z, E-2, 13-octadecadien-1-ol ( 29.99%), chrysophanol ( 15.18%), naphthalene (13.98%), n-hexadecanoic acid (7.00%).[Conclusion] Great diversities in the constituents were found between Polygonum sibiricum and Rheum pumilum.The research provided chemical basis for the understanding, resource protection and appropriate utilization of Tibetan medi-cine Qumazi.
