Article abstract of DOI:10.1016/0031-9422(80)83073-1

Three new diterpenes, pisiferin, 15-hydroxyferruginol, and O-methyl pisiferic acid have been isolated and the presence of 12-hydroxyabieta-8,11,13-trien-20-al has been confirmed in studies of the leaves of Chamaecyparis pisifera.The structure of pisiferin, a phenolic diterpene with a new carbon skeleton, has been determined by chemical degradation.The presence of diterpenes of the ferruginol type in the leaves of four varieties of C. pisifera has been examined.- Key Word Index: Chamaecyparis pisifera; Cupressaceae; diterpenes; pisiferin; 15-hydroxyferruginol; O-methyl pisiferic acid; pisiferal.
