[Objective] To explore transformation of neomangiferin into mangiferin under controlled conditions in vitro,so as to increase the content of mangiferin.[Method] Using Tibetan capillaries(Swertia przewalskii Pissjauk) as tested materials,microorganism fermentation was adopted to realize the transformation of neomangiferin into mangiferin.An efficient strain-screening model was established for selecting strains that could secret specific β-glucosidase by combing category of glycosidic bond with strain-screening technique.Furthermore,these screened strains were isolated,purified and identified.[Result] The upgrade rate of mangiferin content was 0.21% by measuring its content before and after fermentation.[Conclusion] This study was beneficial to reasonable development of mangiferin resource from Tibetan capillaris,which would provide pharmacological and pharmacy evidences for its clinical application.
