Abstract:
OBJECTIVETo study the chemical constituents in bark of Larix olgensis var. koreana.
METHODThe compounds were isolated with silica gel column chromatography and their structures were elucidated on the basis of spectral analysis (IR, EI-MS, 1H-NMR, 13C-NMR).
RESULTEight compounds were isolated and identified as isopimaric acid (I), beta-sitosterol (II), 24R,5alpha-stigmast-3,6-dione (III), larixol (IV), ferulic acid (V), lariciresinol (VI), secroisolariciresinol (VII) and isolariciresinol (VIII).
CONCLUSIONAll the compounds were isolated from this plant for the first time.
