英文摘要：

AIM： To investigate the chemical constituents of Parabarium huaitingii. METHODS： The constituents were isolated and purified by silica gel column chromatography and preparative TLC. Their structures were identified on the basis of spectral data and physiochemical properties. RESULTS： Nine compounds were isolated and their structures were elucidated as physcion （1）, fumaric acid （2）, methyl gentisate （3）, 4-hydroxy-3, 5-dimethoxybenzoic acid methyl ester （4）, syringic acid （5）, 2, 5-dimethoxy-pbenzoquinone （6）, vanillic acid （7）, 3, 4, 5-trimethoxybenzoic acid （8） and 6-methoxy-7-hydroxycoumarin （9）. CONCLUSION： All of the compounds were isolated from this genus for the first time.
