- Two new kaurene diterpenes, 12α-angeloyloxy and 12α-senecioyloxy-9,11-dehydro-ent-kaur-16-en-19-oic acids, have been isolated from Lasianthea fruticosa. The structures and stereochemistry of the compounds were determined on the basis of spectroscopic techniques and minor chemical transformation. The stereochemistry of a few similar compounds has been revised.
