摘要
目的:优选箬竹叶中黄酮的乙醇提取最佳工艺条件。方法:以总黄酮提取率为指标,采用紫外-可见分光光度法测定含量。应用正交试验设计进行筛选。结果:醇提的最佳工艺条件为第1次加8倍量的70%乙醇回流提取60min,第2次加6倍量的70%乙醇回流提取40min,第3次加6倍量的70%乙醇回流提取40min。结论:该优选工艺稳定、可行。
To study the optimal extraction process for flavonoids in the leaves of indocalamus. Method： The extraction rate of total flavonoids as the index and UV-visual spectrophotometry as the determination method for the total flavonoids in extraction solution,the optimal ethanol extraction process was screened by orthogonal design. Result： The optimum process was the following： adding 8 times amount of 70% ethanol and extracting for 40 min, then adding 6 times amount of 70% ethanol and extracting for 40 rain （twice）. Conclusion： The optimized process is stable and efficient.
