英文摘要：

The chemical constituents of Ardisia chinensis, which traditionally used in the area of Yao minority in Southern China, were analyzed and characterized. Seven compounds were obtained from the ethyl acetate fraction of ethanol extract of Ardisia chinensis. These 7 compounds were characterized by spectroscopic analysis and comparison with published data to be salicylic acid （ 1 ） ,4-hydroxy-3-methoxy-benzoic acid （2）, gallic acid ethyl ester （3）, 4-hydroxy-3,5-dimethoxy benzoic acid methyl ester （4）, protocatechuic acid （5）, gallic acid （6） and catechin （7）. All of them were isolated from this plant for the first time, and compound 7 was obtained from this genus for the first time.
