英文摘要 | diabetes mellitus (dm) has become a worldwide health problem alpha-glucosidase inhibitors are widely used in the treatment of type 2 diabetes, and natural products are considered as the promising sources of alpha-glucosidase inhibitors. in this research, ultrafiltration liquid chromatography with photodiode array detection coupled to electrospray ionization tandem mass spectrometry (ultrafiltration lc-pda-esi/ms) were applied to screen and identify alpha-glucosidase inhibitors from scutellaria baicalensis. following this, reverse-phase medium-pressure liquid chromatography (rp-mplc) was applied to separate and isolate the active constituents. as a result, eleven major compounds in s. baicalensis were screened and identified as alpha-glucosidase inhibitors by ultrafiltration lc-pda-esi/ms and six ligands, baicalin, wogonoside, 5,7,3,2',6'-pentahydroxy flavanone, chrysin-6-c-arabinosyl-8-c-glucoside, chrysin-6-c-glucosyl-8-c-arabinoside and wogonin, were isolated by rp-mplc. the purities of the six compounds were 89.7%, 83.5%, 76.2%, 93.7%, 75.1% and 96.2%, respectively, as determined by high performance liquid chromatography. the results demonstrate that the method for systematic isolation of bioactive components in s. baicalensis guided by ultrafiltration lc-pda-esi/ms is a feasible and efficient technique and could be expected to extend for the separation of other enzyme inhibitors. |
