Aster koraiensis extract lowers postprandial glucose in normoglycemic and high-fat-diet-induced obese mice

The Aster koraiensis extract (ASKO) is a newly developed dietary herbal supplement. In this study, the potent blood glucose-lowering activity of ASKO in vitro and in vivo was investigated. In an in vitro glucose uptake assay, ASKO was found to enhance glucose transport in 3T3-L1 adipocytes. Oral administration of ASKO significantly reduced glucose levels in normoglycemic mice during oral glucose tolerance tests (OGTTs). In a long-term efficacy...
