초록

To elucidate chemical structure of the wood extracitives, softwood Larix leplolepis Gorden) metal was extracted with 95% ethanol at room temperature for 72 hours. The extract was fractionated with organic solvents such as n-hexane, chloroform. ether, and ethylacetate. From the n-hexane soluble fraction of the extratives, flavonoid and sterol compounds were isolated and identified as taxifolin(5,7,3',4'-tetrahydroxyflavanonol)(I) and ${\beta}$-sitosterol(II) by UV, IR, $^1$H-NMR spectroscopy and Mass spectrometry.
