摘要
目的:研究民族药飞龙掌血中挥发性化学成分。方法:采用水蒸气蒸馏的方法提取飞龙掌血中挥发油成分,通过正交设计法优选了提取飞龙掌血挥发油的工艺条件;采用气相色谱-质谱联用法(GC-MS)对飞龙掌血挥发油中的化学成分进行了分离鉴定。结果:最佳提取条件为药材粉碎40目,用10倍量水浸泡过夜,连续提取12h,在最佳工艺条件下,飞龙掌血挥发油得率为0.12%,经GC-MS分析,从飞龙掌血挥发油中共鉴定出26个化学成分,鉴定率为97.4%,其主要化学成分为α-杜松醇、斯巴醇、α-紫穗槐烯等。结论:飞龙掌血根和叶挥发油成分差异较大。
Objective：To study the chemical compositions of essential oil from Toddalia asiatica Lam..Methods：The essential oil from Toddalia asiatica Lam.was prepared by the method of Steam Distillation and its chemical compositions were analyzed by GC/MS.Results：The optimal conditions were determined by orthogonal test as follows：40 mesh of samples,12h of extraction time,and 10 times of extraction solvent.Under the optimal conditions,the oil yield was 0.12%.26 compounds were identified,in which the main ingredients were α-Cadinol,spathulenol and α-Amorphene,etc.Conclusion：The chemical compositions of the bark are different from the leaves in the essential oil of Toddalia asiatica Lam.
