毛冬瓜根挥发油化学成分分析

采用水蒸气蒸馏法提取,运用毛细管气相色谱/质谱联用法首次对毛冬瓜根挥发油化学成分进行了分析研究,确认了其中的49种化合物,用气相色谱面积归一法测定各组分的相对百分含量.在分离出的主要挥发性成分中含有烃类(22.26%)、醛酮类(8.52%)、醇类(45.38%)、酚类(1.08%)、羧酸类(7.69%)、酯类(7.18%)、杂环类(2.72%)和环氧类(3.39%)等8大类.在主要成分中以萜类化合物为主(62.20%),包括5种单萜(5.29%)和17种倍半萜(56.91%).其中多种成分为已知药用成分,为进一步评价其质量和开发新药提供了基础数据.

Analysis of the volatile oil from the root of Actinidia eriantha Benth

Volatile oil,extracted from the root of Actinidia eriantha Benth by steam distillation,was analyzed by gas chromatography-mass spectrometry(GC/MS)for the first time. The relative contents in the volatile oil were determined by peak area normalization. 49 compounds have been identified,including eight classes of hydrocarbons(14 kinds,22.26%),aldehydes and ketones(2 kinds,8.52%),alcohols(15 kinds,45.38%),phenol(1 kind,1.08%),carboxylic acids(5 kind,7.69%),esters(5 kinds,7.18%),heterocyclic compounds(3 kinds,2.72%)and epoxides(2 kind,3.39%). Terpenes(62.20%)were found to be the main components,of which the major compounds were monoterpenes(5 kinds,5.29%)and sesquiterpenes(17 kinds,56.91%). The results can provide the basis data for evaluating its quality and for developing new drugs.
