RESUMO
For detecting polyhydroxyalkaloids-type alpha-glucosidase-inhibiting ingredients of Commelina communis L grown in China, total alkaloids were obtained from the plant by extraction with water, removal of precipitation after the addition of alcohol, enrichment and purification by ion exchange resin and sephadex LH 20 chromatography. Polyhydroxyalkaloids in the total alkaloids were detected by ion trap electron-spray ionization mass spectra (ESIMS). Several reported and unreported polyhydroxyalkaloids in the plant were detected from the material collected from Jixi county, Anhui province. The crude drug growing in China contains alpha-glucosidase-inhibiting polyhydroxyalkaloids and can be used to therapy in diabetes.
