Abstract
The aerial parts of Hypoestes verticillaris (L.F.) Sol. (Acanthaceae) has afforded a new seco -fusicoccane diterpenoid ketonepoxide, which was characterized as 1(10) seco -fusicocc-3 (4)-ene-5, 11, 14-trione-8 (9), 1 (7)-diepoxide ( 1 ) on the basis of spectral analysis and named as verticillarone, along with earlier reported diterpenoid, i.e. 13-hydroxy-7-oxo-labda-8, 14-diene ( 2 ).
