Magn Reson Chem. 2012 Apr;50(4):329-31. doi: 10.1002/mrc.2875. Epub 2012 Mar 5.

Abstract

Complete (1) H and (13) C NMR chemical shift assignments for 3,4-seco-lup-20(29)-en-3-oic acid (1) have been established by means of two-dimensional COSY, HSQC, HMBC and NOESY spectroscopic experiments as well as by analysis of MS data. Compound 1 was isolated from Decatropis bicolor (Zucc.) Radlk. (Rutaceae) in addition to six coumarins and one alkaloid of known structure.
