Tetracyclic Triterpenoids, Steroids and Lignanes from the Aerial Parts of Oxypetalum caeruleum

Tetracyclic Triterpenoids, Steroids and Lignanes from the Aerial Parts of Oxypetalum caeruleum

The MeOH extract from dried aerial parts of Oxypetalum caeruleum (Apocynaceae) plants yielded seventeen compounds, including four new tetracyclic triterpenoids, one pregnane glycoside, two lignane glycosides, and ten known compounds. The structures of the new compounds were established using NMR, MS...

Zusammenfassung:The MeOH extract from dried aerial parts of Oxypetalum caeruleum (Apocynaceae) plants yielded seventeen compounds, including four new tetracyclic triterpenoids, one pregnane glycoside, two lignane glycosides, and ten known compounds. The structures of the new compounds were established using NMR, MS spectroscopic analysis and chemical evidence.
