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 Herba Hance. Methods: UV spectrophotometry, total flavonoids content as an index, the level of the preferred factors, select L9 (34) orthogonal design, optimization of the optimum extraction of total flavonoids. Results: The optimum extraction process of total flavonoids was as follows: the herbs were immersed for 15 min, boiled for 3 times, the amount of water added was 45,40,40 times and the boiling time was 1, 0.5 and 0.5 h respectively. Conclusion: The extraction process is reasonable and feasible, which laid the foundation for the further study of Herba Houttuynia.
