increaseing of malondialdehyde (MDA) serum of wistar rats exposed to cigarette smoke. The total
sample of 20 male rats were divided into four groups: negative control, positive control, treatment of red
rosella calyx extract dose 270 mg/bw and red rosella calyx extract dose 540 mg/bw. Negative control
only given with standard feed. Positive control given by standard feed + exposed to 2 cigarettes a day.
Treatment group were feeded by standard + red rosella calyx extract in the morning and exposed to 2
cigarettes after that. This study was conducted for 28 days. At the end of the study, blood serum was
analyzed to determine MDA. The results of the study of MDA serum test was analyzed with One Way
ANOVA and followed by Tukey HSD test at 5% level. The giving of red rosella calyx extract dose 270
mg/bw and red rosella calyx extract dose 540 mg/bw can significantly prevent the increase of MDA
