摘要: 以总黄酮的提取率为考察目标,通过单因素及正交试验,对重瓣臭茉莉根中总黄酮的提取工艺进行优化。结果表明,最佳提取工艺条件为:以25倍量80%乙醇,在80 ℃下回流提取90 min。重瓣臭茉莉根中总黄酮的平均质量分数为2.68%。此优化工艺简单可行且稳定高效,可作为重瓣臭茉莉根中总黄酮的优选提取工艺。

Abstract: Using single factor test and orthogonal test, the optimal processes of extracting total flavonoids from Clerodendrum Chinense (Lour) Merr were established by the absorption of total flavonoids. The optimum conditions for extracting the total flavonoids assisted were as follow: extraction temperature 80 ℃, extraction time 90 min, 80% ethanol and ratio of solid to liquid 1∶25. The mass fraction of total flavonoids extracted was up to 2.68%. It was suggested that the optimum extraction process was simple, stable, efficient and feasible.
