Guided by the hexose transport assay, the hypoglycemic constituents of the aerial part of this plant were disclosed through chromatographic methods. They are fructooligosaccharides, including beta-D-fructofuranose, sucrose, 1-kestose, nystose, and 1(F)-beta-fructofuranosylnystose. The hexose transport assay indicated that nystose was the most potent among these compounds, showing a 46.7% difference from pinitol in the stimulation index at a concentration of 0.5 mg/mL.82 bytestext/htmlGynura divaricata subsp.formosanaCompositaeFructooligosaccharidesNystoseHexose transport assay[SDGs]SDG3http://ntur.lib.ntu.edu.tw/bitstream/246246/258771/1/index.html
