Abstract

Jengkol (Archidendron pauciflorum (Benth.) I.C Nielsen) is a plant that is already familiar in Indonesia and is widely used as a processed food that is quite popular. One of the underutilized parts of the jengkol plant is the skin. Jengkol fruit peel contains alkaloid compounds, flavonoids, tannins, glycosides, sapoinin and steroids or triterpenoids. The purpose of this study was to determine the content of chemical compounds in ethyl acetate extract of jengkol fruit peel, and to test antioxidant activity by DPPH free radical reduction method.The results of isolation, purification in ethyl acetate extract of jengkol fruit skin does not provide activity as an antioxidant. The results of the analysis using FTIR spectrophotometry, Gas chromatography-Mass Spectrometry (GC-MS) and Nuclear Magnetic Resonance Spectroscopy (1HNMR).Keywords: Antioksidan ,archidendron pauiflorum (Benth) I.C Nielsen, jengkol, (1- (2,6-dihydroxy, 4methoxy phenyl) decane-1-one).

Abstract

Kersen (Muntingia calabura L.) has been widely used by Indonesian people to cure many diseases such as cancer, diabetes, and antioxidant, antiplateletes, and hepatoprotector. The aim of this research is to discover chemical structure of compounds contained in barks of Kersen (Muntingia calabura L.) based on their toxicity by BSLT (Brine Shrimp Lethality Test) method. Barks of Kersen (Muntingia calabura L.) were macerated by 96% ethanol followed by partition with n-hexane and ethyl acetate successively to give n-hexane, ethyl acetate and water extracts. Ethyl acetate extract which showed highest toxicity (LD50 = 29.00 ppm) was purified by column chromatography using SiO2 with eluents (i). n-hexane - ethyl acetate = 20 : 1 ~ 1 : 1; (ii). n-hexane - ethyl acetate = 5 : 1 to give fraction 4.4.5 as pure isolated compound. Identification was done based on interpretation of infra red spectrophotometry (FT-IR) and liquid chromatography-mass spectra (LC-MS) data, and supported by references investigation. Finally, we were predicted fraction 4.4.5. as 5-(7,8-dimethoxy-3,4-dihydro-2H-1benzopyran-2-yl)-2,3-dimethoxyphenol  with LC50 = 5.76 ppmKeywords: Hypoglycemic, Diabetes Mellitus, Momordica charantia, Apium graveolens L.
