摘要
目的找到黄花菜中粗黄酮的最佳提取工艺。方法回流法以固液比、醇浓度、提取温度和提取时间为回流提取的4个因素,通过单因素和正交试验进行考察;同时考察超声提取工艺。结果最终最佳提取工艺为固液比60 mL,提取温度95℃,醇浓度95%,提取时间2.5 h。超声提取中提取时间为40 min,醇浓度为90%,固液比为60 mL时提取效率最高。结论回流法提取效率高于超声法的提取效率。
Objective To find lily flower of flavonoids compounds in thick best extraction technology. Methods To solid-liquid ratio,alcohol concentration,extraction temperature,extracting time for the reflux extraction four factors,by single factor experiment,and the orthogonal experiment,finally obtained the reflux extraction method of lily flower of flavonoids compounds in thick best extraction technology;The ultrasonic extraction technology. Results Draw refluxextraction best extraction process：solid-liquid ratio is 60 mL,extraction temperature of 95℃ ,alcohol concentration is95%,and the extraction time of 2.5 h.The ultrasonic extraction of extracting time for 40 minutes,alcohol concentrationis 90%,and the solid-liquid ratio is 60 mL in the highest efficiency extraction. Conclusion Reflux extraction higherthan the ultrasonic extraction,
