英文摘要	The gooseberry (Ribes stenocarpum Maxim. (CBZ)) is a wild and noncommercially cultivated berry fruit widely distributed in the Tibetan Plateau. The phenolic constituents from the berry fruit of CBZ were firstly identified by employing UPLC-QTOF MS. A total of 41 compounds, including hydroxycinnamic acids, hydroxybenzoic acids, flavonols and dihydmflavonol, were identified in view of their molecular weight, characteristic fragment ions and retention times. Further in vitro enzyme assay indicated that CBZ fruit extract could strongly and effectively inhibited alpha-glucosidase and alpha-amylase, with the IC(50 )values of 0.013 mg/mL and 0.005 mg/mL, respectively. In addition, the starch/maltose/sucrose tolerance experiment demonstrated that the CBZ fruit extract could reduce the sucrose mediated postprandial blood glucose (PBG) levels in normal mice, and significantly lower starch/ maltose/ sucrose mediated PBG levels in diabetic mice. These results suggested that this berry fruit could be used as a dietary supplement, or drug for the control of hyperglycemia.
