Water‐Soluble Constituents from the Liverwort Marchantia polymorpha

Four new glycosides, the bibenzyl glycoside α,β‐dihydrostilbene‐2,4′,5‐triol 2,5‐di‐(β‐D ‐glucopyranoside) ( 1 ), the shikimic acid glycoside shikimic acid 4‐(β‐D ‐xylopyranoside) ( 2 ), and two phenylethanoid glycosides 2‐(3,4‐dihydroxyphenyl)ethyl O‐α‐L ‐rhamnopyranosyl‐(1→2)‐β‐D ‐allopyranoside ( 3 ) and 2‐(3,4‐dihydroxyphenyl)ethyl O‐β‐D ‐xylopyranosyl‐(1→6)‐β‐D ‐allopyranoside ( 4 ), together with three known aromatic glycosides were isolated from the H₂O‐soluble fraction of the EtOH extract of the liverwort Marchantia polymorpha. Their structures were elucidated on the basis of chemical and spectroscopic evidences.
