N2  - The title substance was separated from the plant as its methyl ester (IV) and its structure established, partly by conversion into 16&#945;-(-)-kaurane-17,19-dioic acid (VIII) and by other chemical and N.M.R. evidence which locates the secondary hydroxyl. Four known kauranes and a flavone were also isolated from the plant. The conformation of ring c in the 12-oxygenated compounds is discussed.
