Anti-inflammatory Activity of Ethanol Extract of Lotus (Nelumbo nucifera G.) Seed Against White Male Rats Using Paw Edema Method

Abstract

The purpose of this study was to determine the anti-inflammatory activity test of ethanol extract of lotus seeds in rats induced by carrageenan. The research method used was experimental. The object used in this study was male white rats. Observations were made for 6 hours and then the data were analyzed using the one way analysis of variance (ANOVA) test. The anti-inflammatory activity test was carried out on the test animals which were divided into 5 groups, 3 each with the suspension test group with a dose of 200, 300, 400 mg/kg bw, the negative control group was the CMC Na 1% suspension and the positive control was diclofenac Na 2, 25 mg/kg bw. The results showed that the ethanol extract of the seeds of lotus (Nelumbo nucifera G) was proven to have an anti-inflammatory effect on carrageenan-induced male white rats at doses of 200, 300 and 400 mg/kg BW with the percentage value of inflammation inhibition at the 6th hour was 65.79, 74.65 and 80.77%, with the most effective dose in reducing anti-inflammatory drugs being 400 mg/kg bw. The ethanol extract of the seeds of lotus (Nelumbo nucifera) has anti-inflammatory activity. Keywords: anti-inflammatory activity, Nelumbo nucifera, paw edema
