Terpenoids constituents of Euphorbia sapinii

The investigation of an acetone extract of whole Euphorbia sapinii led to the isolation of eighteen terpenoids among which lanost-24-en-20-ol-3-tetradecanoate (1), euphorbol-7-one (2) are new while spectroscopic data of 30-nor-hopan-3β-ol-22-one (3) are reported for the first time. The structures of all compounds were determined using 1D, 2D NMR and MS techniques.

New triterpenoids, lanost-24-en-20-ol-3-tetradecanoate (1) and euphorbol-7-one (2) were isolated form Euphorbia sapinii. Their identification and structure elucidation were based on NMR spectral-data analysis.Highlights► In this study, we separated the constituents of an extract from Euphorbia sapinii. ► We identified the compounds by NMR analysis. ► Lanost-24-en-20-ol-3-tetradecanoate and euphorbol-7-one are new.
