Abstract

Steroids are a group of secondary metabolite which showed various biological activities. Meliaceae is a plant family used as a one of the source of steroid compounds. A. grandis is a member of the Meliaceae family in genus Aglaia which rarely explored. Previous studies have shown that A. grandis leaves contain triterpenoids, steroids, bisamide, and sesquiterpenoids. This study aims to obtain steroids from the bark of A. grandis. The structure of the isolated compound was determined using the NMR 1D and 2 D spectroscopic. Based on the extensive analysis, isolated compound identified as a stigmastant type steroid, stigmast-5-en-3β-ol-7-one.

Abstract

Chisocheton balansae C.DC., is one of the Meliaceae family plants which is the endemic plants from Soputan Mountain, North Sulawesi, Indonesia. This study was aimed to determine the chemical structure of flavan-3-ol compounds from ethyl acetate extract of C. balansae C.DC stembark. Dried powder of C. balansae C.DC stem bark was extracted consecutively with n-hexane, ethyl acetate, and methanol solvents. Four flavan-3-ol compounds, named catechin (1), epicatechin (2), epigallocatechin-3-O-gallate (3), and epicatechin-3-O-gallate (4) were successfully isolated from ethyl acetate extract. The chemical structure of these isolates was determined by spectroscopic methods (1H-NMR, 13C-NMR, DEPT, and 2D-NMR) and comparison with previous reported spectral data. These compounds are first time reported from this plant.
