Phenolic Profiles, Antioxidant, and Hypoglycemic Activities of Ribes meyeri Fruits.

ABSTRACT: Ribes meyeri is a Ribes genus in the Saxifragaceae family, which is used as both medicine and food. However, the active components and biological activities of R. meyeri fruits are still unknown. In this paper, the phenolic components and their antioxidant and hypoglycemic activities of R. meyeri fruits were studied. Firstly, a total of 42 phenolic components of R. meyeri fruits, including 26 anthocyanins, 9 flavonoids, and 7 phenolic acids, were tentatively identified using HPLC-QTOF-MS/MS, and the main four anthocyanins were quantified using UPLC-MS/MS. The result indicated that cyanidin-3-O-rutinoside is the main anthocyanin in the R. meyeri fruits. The anthocyanin fraction of R. meyeri fruits exhibited significant inhibitory activ
