Abstract
Indonesia is the fifth largest producer of mangosteen in the world. West Sumatra is the second largest mangosteen center in Indonesia after West Java. Natural antioxidants can be obtained from mangosteen peel. In this research we used mangosteen from West Sumatera (Padang) and West Java (Muncul, Aeon, Tanah Tinggi, and Sayur Box). The dried mangosteen peel extracted using alcohol. The extraction process using sonication method with a variation of time 30, 45 and 60 minutes, respectively, then evaporated until get the condensed extract. Antioxidant test result from the condensed extract shows that the value of IC50 for mangosteen from all area was 3.76-20.53 ppm. The longer sonication time from AEON has the highest IC50 value (20.27 ppm) than others (3.76-8.11 ppm). From identification using UVvis test, it shows that mangosteen peel contains of flavonoid, tanin, and saponin compound. The mangosteen peel extract from different regions has varying antioxidant activity.
