| Abstract: | From the methanol extract of the Indian liverwort Marchantia polymorpha, two new cyclic bis(bibenzyls), isomarchantin C and isoriccardin C, and a new phenanthrene derivative, 2-hydroxy-3,7-dimethoxyphenanthrene, were isolated together with the previously known cyclic bis(bibenzyls) marchantin A, C, D and E, riccardin C and perrottetin E and their structures were established by extensive 1H NMR spectroscopic examination. Isomarchantin C, isoriccardin C, marchantin C and G, and riccardin C were also isolated from the Indian M. palmata. The two Marchantia species are chemically quite similar. |
