PHENOLIC COMPOUNDS OTHER THAN FLAVONOIDS FROM BRYOPHYTES

抄録

  Phytochemical study of bryophytes has been performed in our laboratory from the chemosystematic point of view. The Hepaticae occasionally produce their own peculiar bisbibenzyl derivatives. These have been found neither in higher plants, fungi nor marine organisms. Marchantin series has been isolated from Marchantia species (Marchantiales). Riccardin series has been found in Riccardia species (Metzgeriales). Plagiochin and perrottetin series occur in Plagiochila and Radula species, respectively. These compounds are useful as chemical markers to interpret chemosystematics of liverworts.
