摘要：

From the red leaf-glands of the Australian P. argentatus the following novel diterpenoids were isolated: coleon-U-quinone (1), 8.alpha.,9.alpha.-epoxycoleon-U-quinone (3), 6.beta.-formyloxy-7.alpha.-hydroxyroyleanone and 5,6-dihydrocoleon U, besides the already known compounds 6.beta.,7.alpha.-dihydroxyroyleanone, 7.alpha.-acetoxy-6.beta.-hydroxyroyleanone and 7.alpha.-formyloxy-6.beta.-hydroxyroyleanone. Epoxydation of 1 by perborate led in 32% yield to the epoxyquinone 3.
