Abstract

Gnetum gnemon L or often known as melinjo is a plant that grows in tropical areas such as Southeast Asia. In addition to the high purine content in melinjo seeds, it turns out that melinjo skin which has been underutilized has many benefits, including the content of polyphenols and flavonoids that can help prevent uric acid disease that often occurs. This study aimed to determine the levels of phenol and flavonoid metabolites in the red melinjo fruit peel fraction. It was held from August to September 2023 at the Pharmacognosy and Chemistry Laboratory of ITSK Dr Soepraoen Hospital Malang. The type of research used was laboratory experiment with Quasi Experimental Design on ethanol fraction, ethyl acetate fraction and n-hexane fraction of melinjo peel. The population used was melinjo fruit leather in RT 15 RW 03 Bantur Village, Malang Regency, East Java. The research sample used melinjo fruit peels that were in good condition and red in color. The study showed that the total flavonoid content in ethanol was 96%; ethyl acetate; n-hexane fractions amounted to 14.2143 mgQE/g; 13.4707 mg QE/g; 31.1703 mg QE/g while the total phenol in ethanol 96%; ethyl acetate; n-hexane fractions amounted to 10.4904 mgGAE/g; 5.5366 mgGAE/g; 9.6911mgGAE/g. The conclused of the study is that melinjo skin contains antioxidants such as total phenols and flavonoids which are quite high, so it has the potential to be used as an alternative source of antioxidants recommended determination total phenol content, flavonoids ethyl acetate fraction of melinjo fruit peel fraction.
