| dc.description.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 stem bark. 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. | en_US |
