Abstract:
AIM: To develop an RP-HPLC method for preparing the reference substanc of vicenin-2 in Desmodium styracifolium. METHODS: Ethanol-extract of desmodium styracifolium was isolated and purified by RP-HPLC combining solvent extraction with column chromatography and recrystalliztion.The purity and content of vicenin-2 were identified by HPLC. RESULTS: The flvonoids were completely separated under this chromatographic condition.The purity of the reference substance was 99.0% or above. CONCLUSION: The method is simple,accurate,better on repeatability,and effective to yield high-purity product.It can be used as reference substance for the research of herbal medicine.
