Combination of these plants was expected to has a synergy effect in reducing cholesterol. However, the toxicity of jati belanda leaves and roselle petals extract combination must be investigated for knowing its safety. Based on the acute toxicity test, the LD50 value of jati belanda leaves and roselle petals extract combination was >5,000 mg/kg bw. It was classified as category 5 or unclassified. This research aimed to study about its effect in cardiac by cardiac histopathology examinations of the rats. The result showed that there was no cardiac histopathology changes of the rats at doses 5,000 mg/kg bw. Keywords: jati belanda leaves, roselle petals, acute toxicity, cardiac histopathology

Abstract

This study aimed to determine the effect of the combination of sidaguri leaves and red ginger rhizome extracts in uric acid levels of hyperuricemic male mice. Thirty-six mice were divided into nine groups including normal group, the positive control (+), negative control (-), extracts of four treatment groups with a variety of combinations and two groups of single extract. Hyperuricemia induction was performed by administering mixture melinjo 10% of the standard feed mice for 7 days dan potassium oxonate 250 mg/kg BB intraperitoneally at 2 hours before blood sampling. The results showed that the combination dose of sidaguri leaves of 50 mg/kg BB and red ginger rhizome 400 mg/kg BB had higher antihyperuricemia activity than other combinations in lowering uric acid levels of mice. Compounds may have antihyperuricemic activity were flavonoids, alkaloids, saponins, tannins, and terpenoids. Keywords: sidaguri leaves, red ginger rhizome, antihyperuricemic activity, uric acid
