Antidiabetic activity of Akar Kuning (Fibraurea tinctoria Lour) Extract in Alloxan-Induced Diabetic White Male Rats
The Akar kuning (Fibraurea tinctoria Lour) is a well-known plant for its potential for the treatment of liver damage and hyperglycemia. However, the main constituent responsible for the anti-diabetic effect is unknown. This study was conducted to investigate the effect of administration of Fibraurea tinctoria Lour ethanol extract on the blood sugar levels in alloxan-induced diabetic male albino rats. All animals were acclimatized with normal feed, and were subsequently divided into 5groups (3rats/ group). Group 1 (negative control group) was given 0.3% NaCMC; Groups 2, 3, and 4 (treatment groups), were given 50, 100, and 200mg/kg BW of Fibraurea tinctoria Lour ethanol extract, respectively once daily for 15 days, while Group 5(positive control group) received 0.65mg/kg BW glibenclamide. Before the treatments, the rats were induced intraperitoneally with 175mg/kg BW alloxan monohydrate. The blood glucose levels were observed every five days. The results showed that the ethanol extract at the doses of 50, 100, and 200mg/kg BW caused a significant decrease (p <0.05) in the blood glucose levels compared to the negative control group. Also, the highest decrease in the blood glucose level was observed in the 100mg/kg BW treatment group. The findings from this study indicate that the ethanol extract of Fibraurea tinctoria Lour has an antidiabetic effect and the 100mg/kg BW dose was the most effective in lowering blood glucose levels.
