Abstract:
Objective: To study the chemical constituents of Euphorbia lunulata. Methods: Separation and purification were performed on silica gel chromatography and HPLC, while their structures were identified on the basis of physicochemical characteristics and spectroscopic data. Results: A new compound was isolated from anhydrous ethanol extracts of E. lunulata. The compound was elucidated as 2α,3β,5α,9α,15β-pentaacetoxy-11,12-epoxy-7β-isobutyryl-8α-benzoyloxyjatropha-6(17)-en-4-one. Conclusion: Compound 1 is a new compound named 8Bz-esulatin A.
