Abstract:Objective:To investigate purification effect of different types of macroporous resin on effective constituents from Fagopyrum dibotrys. Method: With the content of epicatechin and mixture of proanthocyanidins tannic condensation,extract rate as indexes,optimum resin was selected by combining with HPLC fingerprint. Result: Elution rate of epicatechin by AB-8 resin was 89.78%,elution rate of mixture of proanthocyanidins tannic condensation by AB-8 resin was 93.04%.Comparison of the common peak area of HPLC fingerprint showed that AB-8 resin was the most suitable one to purify effective constituents from F. dibotrys. Conclusion: This process of applying AB-8 resin to purity effective constituents from F. dibotrys was feasible, simple and stable and could be extended to large-scale production applications.
