The dried fruits of Amomum tsao-ko were first revealed with hypoglycemic effects on db/db mice at the concentration of 200 mg/kg. In order to clarify the antidiabetic constituents, 19 new flavanol-fatty alcohol hybrids, tsaokoflavanols A-S (1-19), were isolated and determined by extensive
The dried fruits of Amomum tsao-ko are well-known dietary spices and traditional Chinese medicines. The random screen revealed that 50% ethanol-water extract of A. tsao-ko demonstrated significant α-glucosidase inhibitory activity with an IC50 value of 38.6 μg/mL. Bioactivity-guided
Our previous study showed that tsao-ko intake can lower plasma and liver triacylglycerol (TG) concentrations and has hypoglycemic and antioxidant activity in mice. This study involved separating two major fractions (A and B) from the methanol extracts (MeX) of tsao-ko using silica gel column
