THE OCCURRENCE OF FLAVONOIDS IN ARTHRODONTOUS MOSSES―AN ACCOUNT OF THE PRESENT KNOWLEDGE

抄録

  This paper gives an account of all fully characterized flavonoids that have so far been isolated from arthrodontous mosses, and presents also the results of our extensive qualitative studies by 2 D-thin-layer chromatography on the occurrence of flavonoids in these mosses. Altogether nearly 300 species from 59 different families have been studied so far. It is shown that biflavonoids are by far the most common flavonoids in mosses and have been detected in more than two thirds of all species. Flavonoid glycosides, which are very common in hepatics, are, on the contrary, much rarer in mosses; they could be detected in only one fourth of all moss species tested.
