Four Clerodane Diterpenoids From Ptychopetalum Olacoides

A phytochemical component investigation of the bark of Ptychopetalum olacoides led to the isolation of 4 new clerodane-type diterpenoids, namely, ptycholide V (1), 7α,20-dihydroxykolavelool (2), ptycholide VI (3), and ptycholide VII (4). Their structures were elucidated by extensive spectroscopic da...

Zusammenfassung:A phytochemical component investigation of the bark of Ptychopetalum olacoides led to the isolation of 4 new clerodane-type diterpenoids, namely, ptycholide V (1), 7α,20-dihydroxykolavelool (2), ptycholide VI (3), and ptycholide VII (4). Their structures were elucidated by extensive spectroscopic data and comparison of NMR data with that obtained for known compounds.
