The latter include" pimara-8(14),15-diene-3/S,18-diol, abieta-8,ll,13-triene-15,18-diol, 19-hydroxy-15,16-bisnorlabda-8(17)-en-13-one, 8,13i8-epoxylabd-14-en-6a-ol (6a-hydroxy-13-epimanoyl oxide), and the 9,10-secoabietatriene (41). The latter was also isolated from the bark of the jack pine (Pinus banksiana) and western white pine (P. monticola). A range of 7-monohydroxy, 1,7- and 1,11-dihydroxy-, and 1,7,11-trihydroxy-sandaraco-pimaradienes and their acetates (42) have been obtained" from Zexmenia (Compositae) species. The l,ll-diacetoxy-7-ketone and 6,7-epoxide were also isolated. [Pg.167]
