摘要：

The title substance was separated from the plant as its methyl ester (IV) and its structure established, partly by conversion into 16α-(–)-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. © 1968 CSIRO. All rights reserved.
