Three new diterpenoid lactones, odolide iso-odolide and hydroxy odolid
e, isolated from the roots of Gynocardia odorata have been characteriz
ed as ent-kaur-15(16)-en-19 --> 20-olide, ent-kaur-16(17)-en-19 --> 20
-olide and 16 alpha-hydroxy-ent-kauran-19 --> 20-olide on the basis of
spectral and chemical analysis. The higher terpenoids isolated were o
dolactone, trichadenic acid-A and beta-sitosterol.
