摘要
目的优选马缨丹总黄酮的最佳工艺条件。方法以马缨丹中总黄酮的含量为评价指标,采用均匀设计法优选最佳工艺条件。以索氏加热回流提取法提取,芦丁为对照品,采用紫外-可见分光光度仪在406 nm波长处测定吸光度。结果马缨丹总黄酮最佳提取工艺条件为:乙醇体积分数90%,液料比60∶1,药材粉碎度24目,提取时间4 h。结论所优选的工艺可行、重复性好。
Objective To optimize the extraction process of flavonoids from Lantana camara.Methods The total flavonoids from L.camara were determined to obtain the best conditions by uniform design test,using soxhlet extraction method with rutin as reference at 406 nm wavelength.Results The uniform design experiments resulted the optimal process as follows： the extraction with 90% ethanol for 4 hours,the solid-liquid ratio of 1∶60,and particle degree of 24 mesh by soxhlet extractor.Conclusion The optimized technology is feasible with good repeatability.
