摘要：

Three foliose liverworts from the order Jungermanniales were examined for the presence of lignans. They all contained the typical liverwort lignans, i.e. cyclolignans of the dihydronaphthalene and naphthalene type and conjugated with alpha-L-rhamnose, malic acid and shikimic acid, respectively. The new lignans were 3-carboxy-6-methoxy-1-(3',4'-dihydroxyphenyl)-naphthalene-7-O-alpha-L-rhamnopyranoside, 3-carboxy-6,7-dihydroxy-1-(3',4'-dihydroxyphenyl)-naphthalene-9,2"-O-malic acid ester and 3-carboxy-6,7-dihydroxy-1-(3 ',4'-dihydroxyphenyl)-naphthalene-9,5"-O-shikimic acid ester.
