Rambutan (Nephelium lappaceum L) is the original Indonesian tropical fruit. Generally people who eat rambutan only eat the flesh. They throw away the rind which is potential to be a waste. On the rambutan's peel contains antioxidant which potentially becomes basic material of herbal medicine. However another compound has been not discovered yet. Except vitamin C, our body needs some other minerals. This study aims to analyze the vitamin C and other minerals content on rambutan's peel extract. This study uses exploration study design. The sample of the study is rambutan's peel on the Sekaran area, Gunungpati. Focus of this study is to test the vitamin C and minerals (Cu, K, Fe, and Zn) on Rambutan's peel exreact. The vitamin C test uses HPLC and for minerals (Cu, K, Fe, and Zn) uses AAS. The result shows that value of vitamin C on rambutan's rind extract is 0.0003941mg/100mg, while minerals (Cu, K, Fe, and Zn) are 0.0012996 mg/100mg, 0.0001645 mg/100mg, 0.00384 mg/100mg, and 0.0135065 mg/100mg. These results show that the extract contains vitamin C and minerals (Cu, K, Fe, and Zn). © 2019 IOP Publishing Ltd. All rights reserved.
