Abstract
OBJECTIVE: To select the best type of macroporous resin for enriching gentiopicroside from the leaves of Gentiana macropylla, and study its optimal conditions and parameters. METHODS: Adsorption and desorption characteristics of gentiopieroside were carried out on the resins. HPLC was used to determine the content of gentiopieroside. RESULTS: The better resin D-101 was chosen, and the optimal parameters were obtained. CONCLUSION: The process is feasible to enrich gentiopicroside from the leaves of Gentiana macropylla Pall.
