目的:优选陕西产黄花油点草总黄酮提取工艺。方法:用紫外分光光度法,以总黄酮含量为指标,在优选因素水平的基础上,选择L9(34)正交试验设计,优选总黄酮最佳提取工艺。结果:总黄酮最佳提取工艺为:药材浸泡15 min,加水煎煮3次,加水量分别为45、40、40倍量,煎煮时间分别为1、0.5、0.5 h。结论:该提取工艺合理可行,为黄花油点草药材的进一步研究奠定基础。

Objective ： To optimize the extraction technology of total flavonoids from Tricyrtis maculata. Methods ： With UV spectro- photometry as detection method and the content of total flavonoids as index, using single factor experimrnt and L9 （34） orthogonal test, the optimal condition was deterined. Results：The best extraction technology was as follows：soaked the medicinal materials for 15 mi- nutes, water-decoted for 3 times, the solid-water ratio was 1： 45,1： 40,1： 40 and the decotion time was 1,0. 5,0.5 h respectively. Con- clusion：The optimal extraction technolo...
