Abstract:

Zingiber striolatum Diels (Zingiberaceae) is an edible plant resource in the Chinese folk with special efficacy in relieving diabetes and constipation, whichhas been documented in the Compendium of Materia Medica. However, its hypoglycemic activity and constituents have not been reported yet. In the present study, we evaluated the hypoglycemic activity of Z. striolatum in insulin-resistant HepG2 cells, and we developed ultra performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) based chemical profiling method for rapid analysis of Z. striolatum. As a result, the ethanol extract from Z. striolatum showed significant hypoglycemic activity in HepG2 cells, and 22 flavonoids compounds were tentatively characterizedby comparing the retention time and mass spectrometry data. In conclusion, the method of hypoglycemic screening in insulin-resistantHepG2 cells coupled with UPLC-MS/MS is a feasible and credible technique to separate and identify the active constituents in complex matrices of traditional Chinese medicine.
