Study on Enrichment Process of Total Flavones from Semen cuscutae with Macroporous Resin

Objective: To study the optimal conditions and parameters for the enrichment process of total flavones in Semen cuscutae with macroporous resin. Methods: With the enrichment degree of total flavones in Semen cuscutae as an index, the optimal conditions of the enrichment process were investigated. Results: The aqueous extract from Semen cuscutae was taken into the macroporous resin column, then the resin was washed by distilled water to get rid of impurity and 30% and 70% ethannol to elute total flavones. The above conditions were optimal. Conclusions: The process is feasible to enrich effective ingredient flavones from Semen cuscutae.
