CHEMICAL CONSTITUENTS OF 12 SELECTED JAPANESE LIVERWORTS

抄録

  The chemical constituents of 12 selected liverworts were analyzed mainly by GC-MS and the chemical markers of some species were characterized. From Pallavicinia subciliata 6,7-dihydroxy-4-(3,4-dihydroxyphenyl)-naphthalene-2-carboxylic acid was isolated, along with bicyclogermacrene as the major component. This species is closely related chemically to Pellia epiphylla which belongs to the same family Dilaenaceae as P. subciliata. The detection of sesqui- and diterpenoids in Apometzgeria pubescens is the first example of the species belonging to the Metzgeriaceae. The chemical markers of each species will be discussed.
