Chemical shift assignments of two oleanane triterpenes from Euonymus hederaceus

J Zhejiang Univ Sci B. 2005 Aug;6(8):719-21. doi: 10.1631/jzus.2005.B0719.

Abstract

(1)H-NMR and (13)C-NMR assignments of 12-oleanene-3,11-dione (compound 1) were completely described for the first time through conventional 1D NMR and 2D shift-correlated NMR experiments using (1)H-(1)HCOSY, HMQC, HMBC techniques. Based on its NMR data, the assignments of 28-hydroxyolean-12-ene-3,11-dione (compound 2) were partially revised.
