Abstract

Ten highly oxygenated naphthalene and acetophenone derivatives, including five new natural products, have been identified in CDCl₃ extracts of Adelanthus decipiens from Scotland, Wales, Ireland, Colombia and Ecuador. Although not all ten compounds were detected in the extracts of all the eight liverwort gatherings examined (two fresh and six herbarium specimens), the general picture is one of different distributions of compounds rather than the presence or absence of particular compounds in the different samples of liverwort. 1,2-Dimethoxy-3,4-methylenedioxynaphthalene (wettstein A) is the major component in material from the British Isles whereas 1,2,4-trimethoxynaphthalene is the major component in one Colombian specimen and 1,2,3-trimethoxynaphthalene is the major naphthalene derivative in another (the subject of a GC-MS study in 1980). Pentamethoxyacetophenone is the major component in the specimen from Ecuador. The feasibility of using small amounts of herbarium material to undertake this type of study has been demonstrated.
