摘要
目的对牛至挥发油的正交提取工艺进行研究,确定最佳工艺条件。方法采用水蒸气蒸馏法提取牛至挥发油,同时采用气相色谱法,以牛至主要抗菌成分对-聚伞花素、麝香草酚、香荆芥酚为标示成分,对牛至挥发油进行质量评价。结果确定了牛至挥发油的最佳提取工艺:加药材重量的10倍量水,浸泡30min,提取6h,收油率为0.49%。结论采用水蒸气蒸馏法提取牛至挥发油,稳定可行。
Objectve To research the extraction process of Origannum vulgare L. ,to determine the optimum extraction. Methods The essential oil of Origannum vulgare L. extracted by steam distillation , at the same time using GC with the major antibacterial component of p - cymene, thymol, carvacrol as a marked component for quality evaluation , optimal extraction process. Results The best extraction process of Origannum vulgare L. is： add 10 times the weight of water, Soak 30 minutes, Extraction of 6 hours, closed oil rate of 0. 49%. Conclusion The essential oil of Origannum vulgare L. extracted by steam distillation , stable and viable.
