Mei et al. [82] found that the ethanol extracts of both agarwood and A. sinensis leaves alleviated diabetes induced by mesoxyalyurea in mice. The methanol extract of A. sinensis leaves possessed the fast blood glucose activity in rat and glucose uptake transportation by rat adipocytes [83]. Iriflophenone 3-C-β-glucoside decreased the fasting blood glucose levels in streptozocin-induced diabetic mice, and enhanced glucose uptake into adipocytes [84]. Compounds 146149 isolated from agarwood had an inhibitive effect on α-glucosidase [44].
