The Effect of Red Dragon Fruit Extract (Hylocereus Polyrhizus) on Membrane Lipid Peroxidation and Liver Tissue Damage Triggered by Hyperlipidemia in White Rats (Rattus Norvegicus)

摘要

This study aims to prove that the administration of red dragon fruit extract (Hylocereus polyrhizus) has an effect on membrane lipid peroxidation and liver tissue damage triggered by hyperlipidemia in white rats (Rattus norvegicus). This study used true-experimental design with using 30 male Wistar rats which were divided into 5 groups. Group K1 - K4 was given treatment for 8 weeks and group K5 for 16 weeks. The group consists of K1 negative control (standard diet); K2 positive control (standard diet and quail eggs 10 ml / kgBW); K3 (standard diet, quail eggs 10 ml / kgBW and simvastatin 0.72 mg / day); K4 (standard diet, quail eggs 10 ml / kgBW and red dragon fruit extract dose 60 mg / day) for 8 weeks and K5 (standard diet, quail eggs 10 ml / kgBW and red dragon fruit extract dose 60 mg / day) for 16 weeks. Data was analyzed by One Way ANOVA test, followed by the Wilcoxon Man-Whitney Post Hoc test (P-value <0.05) in 8 weeks treatment. K3 and K4 groups showed improvement in MDA concentration and improvement of liver tissue (P-value <0.05) compared to K2. Red dragon fruit extract 60 mg/day has a potential effect in repairing lipid peroxidation damage on liver cell membrane in hyperlipidemia conditions with high fat diet.
