Type 2 diabetes mellitus is a chronic metabolic syndrome characterized by hyperglycemia which can further develop microvascular and macrovascular complications. Aquilaria crassna L. was reported as a traditional Thai medicinal plant that possesses an anti-diabetic effect in animal model. The present study revealed the mechanism by which this plant extract lowered glucose levels in cultured hepatocellular cell line, HepG2. ALE at a concentration of 6.25, 12.5 and 25 μg/ mL significantly increased glucose consumption in a dosedependent manner. The increase of glucose consumption of ALE-treated HepG2 cells was accompanied by 2-fold increase of the glycogen synthase 2 (GYS-2) mRNA expression and 50% suppressing of glucose-6-phosphatase expression. These data indicate that the anti-diabetic effect of ALE on HepG2 cells is mediated through the increased of glycogen synthesis and the decrease of gluconeogenesis. Gas-chromatography and mass spectrometry (GC-MS) analysis of the ethanolic extract of ALE consisted of nitrogen containing compounds (39%), terpenoids (31%), polyketide (18%), and phenylpropanoids (12%). Investigation of glucose-lowering effect of these compounds is currently underway.
