| Abstract: | Four new phenolic glycosides, named rebouosides A–D ( 1 – 4 , resp.), along with three known ones 2‐(3,4‐dihydroxyphenyl)ethyl 2‐O‐α‐L ‐rhamnopyranosyl‐β‐D ‐allopyranoside ( 5 ), 2‐(3,4‐dihydroxyphenyl)ethyl β‐D ‐allopyranoside ( 6 ), 2‐(3,4‐dihydroxyphenyl)ethyl β‐D ‐glucopyranoside ( 7 ), and a nucleoside, inosine ( 8 ), were isolated from Chinese liverwort Reboulia hemisphaerica. Their structures were elucidated by acidic hydrolysis and extensive spectroscopic methods, including 2D‐NMR techniques. |
