520 3 _aThe seed of Trigonella foenum-graecum L. (fenugreek)has been reported to be rich in saponins, especially the dioscin or diosgenin, which are natural anti-diabetic agents with relatively low toxicity. Thus, the present study was to purify the saponins and sapogenins from fenugreek and to evaluate their ?-glucosidase inhibitory activity in vitro. As a result, 33 steroidal saponins and sapogenins were isolated, including six undescribed ones and 27 previously known molecules. Among them, compounds 10, 12, 17, 22 and 29 were five 25R and 25S isomer mixtures of spirostanol saponins or sapogenins. The structures of compound 1-6 were established by 1D and 2D NMR spectroscopic analyses, high-resolution mass spectrometry, and chemical evidence. Compared to the positive control, sapogenins 26, 27, 14 and saponins 18 and 23 considerably inhibited ?-glucosidase at IC50 values of 15.16, 8.98, 7.26, 5.49 and 14.01 ?M, respectively. These results support the therapeutic potential of fenugreek in the treatment of diabetes with saponins and sapogenins as the active constituents.
