, 2023
Laeviganoids A–T (1–20), 20 new ent-clerodane-type diterpenoids featuring a 2-furanone (1–3) or a furan (4–20) ring, as well as six analogues (21–26), were isolated from the roots of Croton laevigatus.

Rearranged (4→2)-abeo-clerodane and clerodane diterpenes from Aristolochia chamissonis

Phytochemistry, 1999
Abstract From stems of Aristolochia chamissonis Duch., five new diterpenes, one rearranged (4→2)-abeo-clerodane and four ent-clerodanes, were isolated. Their structures were determined to be (+)-(4→2)-abeo-kolavelool-3-oic acid, (−)-13-epi-2-oxokolavelool, (−)-2β-hydroxykolavelool, (−)-2β-hydroperoxykolavelool and (+)-13-epi-2α-hydroxykolavelool.

Clerodane Diterpenoids from Salvia splendens

Journal of Natural Products, 2006
Four new clerodane diterpenoids, salvisplendins A-D (1-4), have been isolated from an acetone extract of the flowers of Salvia splendens, together with an artifact (5), arising from salvisplendin D (4) by addition of diazomethane, and the already known clerodane olearin (6). The structures of the new compounds (1-5) were established mainly by 1D and 2D

Clerodane diterpenes from leaves of Casearia sylvestris Swartz [PDF]

Química Nova, 2007
Ethanolic extracts of the leaves of Casearia sylvestris yielded a novel clerodane diterpene, 15-hydroxy-3-cleroden-2-one, together with the known diterpenes (-)-hardwickiic acid, reported for the first time from this species, and casearins B and G ...

Clerodane diterpenoids from Salvia blepharophylla

Phytochemistry, 1999
Abstract Two clerodane diterpenoids, blepharolides A and B, have been isolated from Salvia blepharophylla Brandegee ex Epling. Their structures were determined using a combination of one- and two-dimensional NMR techniques. The relative stereochemistry for blepharolide A was determined by X-ray diffraction.

Ent-Clerodane derivatives from Chromolaena connivens

Phytochemistry, 1989
Abstract The aerial parts of Chromolaena connivens afforded in addition to widespread compounds four ent -clerodane derivatives and two epimeric prostaglandin-like acids. A second species, C. turnariensis , only gave widespread compounds. The structures were elucidated by high field NMR techniques.

Epoxy Clerodane Diterpene Attenuates the Differentiated Adipocyte Hypertrophy and Enhances Mitochondrial Metabolism. [PDF]

ChemistryOpen
Epoxy Clerodane Diterpene (ECD) significantly reduces adipocyte hypertrophy and lipid accumulation in human mesenchymal stem cell (hMSC)‐derived adipocytes. ECD improves mitochondrial membrane potential (ΔΨm), increases thermogenic regulators (UCP‐1, PPARγC1α), decreases adipogenic markers (C/EBPα, PPARγ), and reduces inflammatory mediators (TNF‐α, NF ...

Clerodane Diterpenoids from Croton crassifolius

Journal of Natural Products, 2012
Seven new clerodane diterpenoids (1-7) were isolated from roots of Croton crassifolius, along with six known compounds. The structures were elucidated by extensive spectroscopic methods (IR, UV, HRESIMS, 1D NMR, and 2D NMR), and the structures of 1, 3, 4, and 7 were confirmed by single-crystal X-ray diffraction analyses.
