Clerodanes and Other Constituents of Cleidion Spiciflorum
Phytochemistry, 2006The polyoxygenated clerodane, spiciflorin (1a), was isolated from Cleidion spiciflorum (Burm. f.) Merr. (Euphorbiaceae). Other constituents were the glucoside of anol (2), columbin, scopoletin, 3,3',4-O-trimethylellagic acid, acetylaleuritolic acid, common triterpenes and phenols.

Abstract The aerial parts of Conyza hypoleuca gave in addition to known compounds,nine new clerodane derivatives, four secoclerodanes, three geranyl geraniol derivatives and five unusual sesquiterpenes derived from 10-sesquigeranic acid. The structures were elucidated by high field NMR techniques.

Clerodanes From Polyalthia viridis
Phytochemistry, 1993Abstract Study of a somewhat polar fraction of the extract of Polyalthia viridis bark furnished the new clerodane 3,12 E -kolavadien-15-oic acid-16-al, a bis-clerodane imide and several known clerodane derivatives. The structure assigned to polyalthialdoic acid from P. longifolia is discussed.

Scutefolides A1 and A2, two acylated neo-clerodanes with a 19,18-γ-lactone, scutefolides B1, B2 and C, three 19-nor-neo-clerodanes, together with scutefolides D, E1, E2 and F, four neo-clerodanes, were isolated from the EtOAc-soluble fraction of the aerial parts of Scutellaria coleifolia.

Clerodane and 5 10-Seco-Clerodane-type diterpenoids from Salvia involucrata
Journal of Molecular Structure, 2021Abstract From the leaves of Salvia involucrata Cav., eight clerodane diterpenoids were isolated, of which 1−3 have not been previously described. Their structures were established by spectroscopic and spectrometric means and named as involucratin A (1), involucratin B (2), and involucratin C (3).

Diterpene Foliar Exudates of Blakiella Bartsiifolia and Phytotoxicity of Clerodanes
Natural Product Communications, 2014 Blakiella bartsiifolia (S.F. Blake), an endemic and rare high altitude plant of the northern Andes, appears well adapted to the prevailing harsh environment owing in part to a thick glandular trichome cover.
