Antioxidant Activity of Anthocyanin from Ethanol Extract of Purple Sweet Potato (Ipomoea batatas L)
Kata Kunci:
Purple sweet potato, anthocyanin, antioxidant activityAbstrak
Purple sweet potato is widely used as a traditional medicine to treat various types of diseases. The purple color of sweet potatoes is caused by the presence of a natural dye called anthocyanin. This anthocyanin compound has many functions, one of which is as an antioxidant. This study aims to determine the antioxidant activity of anthocyanin compound purple sweet potato extract (Ipomoea batatas L). This research consists of several stages of maceration, testing with Thin Layer Chromatography (TLC), and antioxidant activity. From the research results obtained extract of sweet potato purple more or less 300 mL. In TLC test obtained Rf value of 0.5 indicating anthocyanin compound cyanidin 3-rhamnosida. Furthermore, the measurement of antioxidant activity obtained results of 61.05%.
