Widowati AK, Hikmayani NH, Pamungkasari EP. 2012. Antipyretic effect of key lime (Citrus aurantifolia) leaf extract on white rats. Biofarmasi 10: 35-39. The objective of this study was to evaluate the antipyretic effect of key lime (Citrus aurantifolia L.) leaf extract on white rats (Rattus norvegicus) induced fever by using DPT vaccine. Thirty male white rats with the body weight of ±200 grams and the age of 2-3 months old were used in this study. Those rats were grouped equally into five groups, consisted of a negative control group (2 mL aquabidest), a positive control group (acetaminophen 6.3 mg/100 g of body weight), the first dose of key lime leaf extract (1.26 mg/100 g of body weight), the second dose (2.52 mg/100 g of body weight) and the third dose (5.04 mg/100 g of body weight). The measurement of rat temperature was conducted before and 2 hours after getting DPT vaccine, and every 30 minutes posttreatment until 120 minutes. Data at the 120th minute were analyzed by using One-Way Anova test. The results of One-Way Anova test showed that there were significant differences (p<0.05) among treatment groups. The results of post-hoc test analysis showed that the significant differences (p<0.05) were found between a negative control group and four other groups. There was no significant difference (p>0.05) between a positive control group and three groups of key lime leaf extract. It concluded that the key lime leaf extract has an antipyretic effect on white male rats.
