摘要
采用水蒸气蒸馏法提取石山巴豆和毛果巴豆叶中的挥发油,利用GC-MS联用仪对其化学成分进行分析和鉴定,以归一化法计算各个化学成分的相对含量。结果表明:从石山巴豆叶鉴定出39种化合物,占总量的95.96%,主要成分是α-松油醇(17.57%)、桉树醇(11.13%)、乙酸松油酯(9.07%)、倍半水芹烯(8.52%)等;从毛果巴豆叶鉴定出55种化合物,占总量的97.8%,以反式-橙花叔醇(9.48%)、α-松油醇(7.51%)、桉树醇(6.43%)、乙酸松油酯(6.72%)为主要成分。两种植物叶中的挥发油成分均以萜醇、倍半萜烯为主,并且其中多种成分具有生物活性,因此研究结果可为石山巴豆和毛果巴豆的开发利用提供科学依据。
The volatile oils of leaves of Croton euryphyllus and C.lachynocarpus were extracted by steam distillation and analyzed by GC-MS.Through peak area normalization method,39 components were identified from leaves of C.euryphyllus and the main compounds were α-terpineol(17.57%),eucalyptol(11.13%),erpinyl acetate(9.07%),and α-sesquiphellandrene(8.52%) et al.Meanwhile,55 compounds,constituting ca.97.8% of the volatile oil,were inentified from leaves of C.lachynocarpus and trans-nerolidol(9.46%),α-terpineol(7.51%),eucalyptol(6.43%) and erpinyl acetate(6.72%) were found to be major compounds.In two plants,the structure types of main volatile components were terpene alcohols and sesquiterpenes,and many compounds showed bioactivities.This research would provide theoretical basis for the development and utilization of C.euryphyllus and C.lachynocarpus.
