Neo-clerodane diterpenoids from Clerodendrum inerme

Three neo-clerodane diterpenoids, inermes A, B, 14,15-dihydro-15β-methoxy-3-epicaroyptin in addition to 14,15-dihydro-15-hydroxy-3-epicaroyptin have been isolated from the hexane extract of the leaves of Clerodendrum inerme. Structures of these compounds have been elucidated on the basis of spectral studies.
