Distribution of cyclic bis(bibenzyls) in the South African liverwort Marchantia polymorpha☆

The previously known cyclic bis(bibenzyls), marchantin C and H, and riccardin C have been isolated from the South African liverwort Marchantia polymorpha, together with two sesquiterpenoids, (−)-cuparene and (−)-2-hydroxycuparene, and p-hydroxybenzaldehyde. This is the first report of the isolation of marchantin H from Marchantia species. The South African species differs chemically from the Japanese, Indian French and German species.
