dc.description.abstract | Background: Chrysanthemum plants (Chrysantemum morifolium R.) belong to the Astereceae family and the Chrysanthemum genus. Chrysanthemum plants (Chrysantemum morifolium R.) contain active compounds in the form of saponins, steroids, flavonoids, tannins, terpenoids, alkaloids, polyphenols and lignin. Chrysanthemum also contains antioxidants, which are compounds that can prevent and slow down damage caused by free radicals by inhibiting oxidative mechanisms. Antioxidants can help protect the body from damage caused by reactive oxygen compounds and other free radicals.
Objective: This study aims to determine the antioxidant activity in the infusa of snow white chrysanthemum flowers (Chrysanthemum morifolium (Ramat.) Hemsl.).
Methods: Infusa sample of snow white chrysanthemum flowers were analyzed for antioxidant activity by DPPH method using UV-Vis Spectrophotometry at a wavelength of 515.5 nm.
Results: Results of antioxidant activity testing in the infusa of snow white chrysanthemum flowers showed an IC50 value of 0.319 μg/ml with a very strong category, while quercetin had an IC50 value of 11.616 μg/ml with a very strong category.
Conclusion: The infusa of snow white chrysanthemum flowers has very strong antioxidant activity. | en_US |
