Abstract

Objective:To study on chemical constituents of the ethyl acetate extract part of Stelmatocrypton khasianum. Method: Ethyl acetate extract part were isolated and pured by silica gel column chromatography

MCI and Sephadex LH-20

Their chemical structures were elucidated by spectral data analysis(1H-NMR and13C-NMR). Result: Five compounds were isolated from the ethyl acetate extract part

they were identified as syringaresinol (Ⅰ)

diasyringaresinol (Ⅱ)

episyringaresinol (Ⅲ)

justiciresinol (Ⅳ)
