, p. 1837 - 1838 (1984)
The structure of pisiferin has been revised, and the double bond isomer, named isopisiferin, has been found in the seed of Chamaecyparis pisifera.

Key Word Index - Chamaecyparis pisifera; Cupressaceae; chemotaxonomy; mono-, sesqui- and diterpenes; 20-nor-abietane; 9(10 -> 20)-abeo-abietane. - Six new diterpenes, 12-hydroxy-20-nor-abieta-1(10),2,8,11,13-pentaene, pisiferanol (10S,12-dihydroxy-9(10 -> 20)-abeo-abieta-8,11,13-triene), pisiferadinol (20S-hydroxypisiferanol), 12-deoxypisiferanol, 1β-hydroxyisopisiferin (1R,12-dihydroxy-9(10 -> 20)-abeo-abieta-8,10(20),11,13-tetraene), and the dimethylamine salt of O-methylpisiferic acid were isolated from the seed of Chamaecyparis pisifera.The structures of these diterpenes were established by spectral and chemical methods.In addition, 15 mono-, four sesqui- and nine diterpenes were identified.
