Pendahuluan: Cengkih (Syzygium aromaticum) mengandung eugenol dipercayamemiliki efek antioksidan untuk menangkal paparan radikal bebas. Penelitian inibertujuan untuk membuktikan efek antioksidan cengkih terhadap kerusakan fungsi hatitikus Wistar yang diinduksi oleh CCl4 dengan melihat kadar Malondialdehida (MDA)hati sebagai hasil peroksidasi lipid. Metode: Tiga puluh enam tikus Wistar yangberusia 12 minggu dibagi menjadi 6 kelompok, yaitu kontrol negatif (CCl4), kontrolpositif (CCl4 + α-tokoferol), dan 4 kelompok dengan pemberian CCl4 dan cengkihselama 1 hari, 3 hari, 5 hari, dan 7 hari. Hasil: Digunakan uji One-way ANOVAdengan uji perbandingan post hoc LSD. Didapatkan rerata kadar MDA (nmol/mgprotein) kontrol positif (0.0140), kontrol negatif (0.0098), 1 hari (0.0370), 3 hari(0.0660), 5 hari (0.0849) dan 7 hari (0.0968). Terdapat perbedaan bermakna (p <0.05)antar kelompok pada uji One-way ANOVA. Berdasarkan uji post hoc LSD,peningkatan kadar MDA dibandingkan kontrol negatif signifikan (p<0.05) padacengkih 1 hari, 3 hari, 5 hari, dan 7 hari. Kesimpulan: Peningkatan kadar MDAmenandakan adanya peningkatan stress oksidatif pada kelompok yang diberikancengkih. Dengan demikian, cengkih bersifat hepatotoksik karena menyebabkankerusakan membran lipid.
ABSTRACT
Introduction: Clove (Syzygium aromaticum) contains eugenol as its main compoundknown for its antioxidant effect against free radicals. This study was conducted toinvestigate the antioxidant effect of Clove against CCl4-induced Wistar ratshepatotoxicity by measuring liver Malondialdehyde (MDA) level as one of occuringproducts of lipid peroxidation. Methods: Thirty–six Wistar rats at the age of 12–weeks were divided into six groups: positive control (given CCl4 and α-tocopherol),negative group (CCl4 only), and 4 groups were given CCl4 and clove extract for 1 day,3 days, 5 days, and 7 days each. Results: One-way ANOVA with post hoccomparisons (LSD) were performed across all groups. There was a significantdifference (p<0.05) in mean MDA level (nmol/mg protein) between positive control(0.0140), negative control (0.0098), 1 day of clove (0.0370), 3 days clove (0.0660), 5days clove (0.0849) and 7 days clove (0.0968). The mean MDA levels aresignificantly higher (p<0.05) in groups that were given 1, 3, 5, and 7 days of cloveextract respectively than the negative control group. Conclusions: Higher MDA levelsin clove-given groups indicated increased oxidative stress caused by clove. Therefore,clove has hepatotoxic effects in Wistar rats instead of antioxidant effects |
