OBJECTIVE To investigate the chemical constituents of the two liverworts Dumortiera hirsute and Pallavicinia ambigua.METHODS Chromatography was used to isolate and purify chemical constituents, and their structures were elucidated based on spectral evidence together with physiochemical properties.RESULTS Five compounds were isolated from the two plants and identified as: ethyl shikimate (Ⅰ), 3, 4-O-isopropylideneshikimic acid (Ⅱ), luteolin (Ⅲ) , 3-carboxy-6,7-dihydroxy-1-(3′,4′-dihydroxyphenyl)-naphthalene (Ⅳ) and 3-carboxy- 6,7-dihydroxy- 1- (3′,4′- dihydroxy- phenyl)-naphthalene-9,5″-O-shikimic acid ester (Ⅴ).CONCLUSION Compound I is obtained for the first from natural sources while compound II is an artifact produced during the separation process; Compound Ⅳ and Ⅴ were isolated from the Pallaviciniaceae for the first time.
