Abstract

The Tetraceraindicahasbeen used traditionally to treat various diseases including skin medications, lower blood pressure, fever, headache, wound andgout medicine.   The objective of the research was isolatedand characterizedthe ?-sitosterol (1) and betulonicacid (2) fromn-hexaneextract of the stem bark of Tetraceraindica.  The dry powder thestembark (550 g)wasmaceration with n-hexane for 24 hrs.Thisextraction process was repeated three times.  The n-hexane extract was separated and purified by chromatographytechnique. The structure of isolatedcompound wasdetermined by spectroscopy data UV, IR, NMR and compared with reported data.  Two compounds have been isolated and base on spectroscopy data thecompounds is ?-sitosterol (1) andbetulonic acid (2).   Betulonic acid is being reported for the first time from T.indica,meanwhile the?-sitosterolpreviously reported from MeOHextractof leaves of T. indicabut  is being reported for the first time from the stembarkof  T.indica.

Abstract

Tetracera indica Merr. in Musi Banyuasin, is one of the traditional medicine used by the community for the treatment of kidney stone disease and gout, but this claim is not recorded in the treatment of kidney stones and gout in Indonesia.  In this study, isolation of antioxidant compound from ethyl acetate extracts of supit (Tetracera indica) was done. The isolation was carried out through step gradient polarity extraction, and separated and purified by chromatography technique. The determination of the structure of the isolated compound was performed by spectroscopy method including UV, IR, and NMR 1D and 2D, and antoxidant activity was determined  by DPPH method.  An  active antioxidant compound was isolated from ethyl acetate extract in form of yellow solid (15 mg).  Based on spectroscopic analysis the isolated compound was 5,8-dihydroxy-7-methoxyflavone.  The compound showed strong antioxidant activity (IC50 8.25 μg/mL) higher than standard ascorbic acid (IC50 11.3 μg/mL).  This data concluded that efficacy of supit (Tetracera indica) for the treatment related to antioxidant activity (uric acid) is proven by the identification of one antioxidant compound of this plant.
