Abstract

From the leaves of R. ternifolia (D. Don) Hara (Labiatae), a new diterpenoid, isodonoic acid was isolated and the structure was established by spectroscopic and chemical evidence. Three known diterpenoids, isodonal, longikaurin E and longikaurin A were also isolated together with oleanolic acid and stearic acid.
