Antidiabetic activity of Lyophyllum decastes in genetically type 2 diabetic mice.

The antidiabetic activity of Lyophyllum decastes (Tricholomataceae) was investigated in KK-Ay mice, an animal model of genetically type 2 diabetes with hyperinsulinemia. The water extract of Lyophyllum decastes (LD) (500 mg/kg body weight) reduced the blood glucose of KK-Ay mice 7 h after a single oral administration (p<0.05) when compared with control.
