• Clerodendron tomentosum
• diterpenoid quinones
• 12-acetylroyleanone
• triterpenoids

Chemical investigation of combined pet. ether and benzene fractions from the ethanolic extract of Clerodendron tomentosum R. Br. afforded three diterpenoid quinones, viz. 12-acetylroyleanone, royleanone and 6,7-dehydroroyleanone along with n-hexacosane, eicosanoic acid, (24S)-ethylcholesta-5,22,25-triene-3 beta-ol, alpha-amyrin and oleanolic acid. This is the first report of the isolation of diterpenoid quinones from this plant, also 12-acetylroyleanone has been obtained for the first time from a natural source.
