For a few 50 years, Professor Asakawa and his workforce have targeted their learn at the chemical elements of bryophytes and feature chanced on that those vegetation include huge numbers of secondary metabolites, comparable to terpenoids, acetogenins, and fragrant compounds consultant of many new skeletons, which express fascinating organic actions. person terpenoids, while stumbled on as components of either a bryophyte and the next plant, are likely to happen in numerous enantiomeric varieties. Professor Asakawa has coated the literature on bryophytes in prior volumes of Progress within the Chemistry of natural traditional Products, particularly, Volumes forty two (1982) and sixty five (1995). because the booklet of the latter quantity, loads of new info has seemed on bryophytes. One instance is that identified intercourse pheromones of algae were came across in liverworts, indicating that a few individuals of the latter taxonomic crew may originate from brown algae. From info supplied during this quantity, it is recommended that orders of the Marchantiophyta might be mixed.
