摘　　要：目的:筛选车前草中总苯乙醇苷提取的最佳工艺。方法:以总苯乙醇苷的量为指标,采用单因素试验和正交试验优化车前草中总苯乙醇苷最佳提取工艺。结果:车前草中总苯乙醇苷的最佳提取工艺为:车前草粉末(过2号筛)加入25倍量、50%的乙醇并调节p H值为5,于95℃加热回流提取两次,每次120 min。结论:研究结果表明,该提取工艺简单、可靠、重复性好,为车前草的进一步深度开发奠定基础。Objective： To screen the best extraction process for the extraction of phenylethanoid glycosides from Plan- tago Herba. Methods： Taking the amount of phenylethanoid glycosides as the index, the extraction process for the extraction of phenylethanoid glycosides from Plantago Herba was optimized by single factor experiment and orthogonal test. Results： The op- timum extraction process of the content of the phenylethanoid glycosides from Plantago Herba was follows ： the powder of Planta- go Herba was 25 times of the amount of 50% ethanol, and the pH value was 5, and the reflux extraction was extracted for two times at 95 ℃. Conclusion： The results show that the extraction process is simple, reliable and reproducible, which lays the foundation for the further development of the herb.
