摘要	Five new diarylheptanoids, kaemgalangins A-E (1-5), and seven known ones were isolated from the rhizomes of Kaempferia galanga. The structures of new compounds were identified by spectroscopic analyses involving 1D and 2D NMR, HRESIMS, IR, UV, [alpha]D, ECD calculations, and chemical methods. All compounds were tested for their hypoglycemic effects against alpha-glucosidase, Gpa and PTP1B enzymes, and stimulative effects on GLP-1 secretion. Kaemgalangins A (1) and E (5) showed significant inhibition on alpha-glucosidase with IC50 values of 45.3 and 116.0 mu M; renealtin B (8) showed inhibition on GPa with an IC50 value of 68.1 mu M; whereas all compounds were inactive to PTP1B. Docking study manifested that 1 well located in the catalytic pocket of alpha-glucosidase and OH-4 '' played important roles in maintaining activity. Moreover, all compounds showed obviously stimulative effects on GLP-1 with promoting rates of 826.9%-1738.3% in NCI-H716 cells. This study suggests that the diary-lheptanoids in K. galanga have antidiabetic potency by inhibiting alpha-glucosidase and Gpa enzymes, and promoting GLP-1 secretion.
