抄録
The constituents of three Costa Rican ferns of Pteridaceae were investigated. From Jamesonia scammanae A. TRYON, a new pterosin-type compound (I), named jamesonin, along with two pterosin derivatives and six ent-kaurane-type diterpene derivatives were isolated, and I was established as (2R, 3R)-3-hydroxy-6-(2-hydroxyethyl)-2, 7-bishydroxymethyl-2, 5-dimethylindan-1-one by spectroscopic methods. From Dicksonia gigantea KARST., two known pterosin derivatives were isolated, and from Paesia anfractuosa C. CHR., two flavonol glycosides.
