Abstract
Oxidative stress is an imbalance between oxidants and antioxidants that can lead to impaired signaling and redox control. Free radicals in large quantities will stimulate the production of IL-6 and TNF-, which act as proinflammatory cytokines and trigger the release of polymorphonuclear cells (PMN); this makes antioxidants are needed to inhibit the oxidation process and free radicals prevention. One of the natural antioxidants that is easy to find and become a symbol of beauty and love is the rose (Rosa chinensis Jacq.). The purpose of this study was to know secondary metabolic compounds and total antioxidant capacity on methanol extracts of rose flower. This research is an experimental research using methanol solvent with maceration method that includes phytochemical screening test consisting of 12 secondary metabolic compounds by Harborne and total antioxidant capacity test by DPPH method (1,1-Diphenyl-2- Picrylhydrazyl) by Blois. In the qualitative test, rose flower extracts contain cardioglycosides, alkaloids, flavonoids, anthocyanins and betacyans, coumarins, glycosides, phenolics, quinones, tannins, and terpenoids. The test results of the total antioxidant capacity showed that the IC50 of rose flower was 69,42 μg/mL. These results indicate that rose flower extract has potential as a strong antioxidant to prevent many diseases such as cancer.
