Abstract Three new rare triterpenes, the paleo-biomarkers gammacer-16-ene-3-one and messagenolide, and the firstnaturalcarbonatederivativesoyasapogenolG, were isolated from allelopathic bioactive fractions of Melilotusmessanensis L. Their structures were established by chemical correlations and spectroscopic ( 1 H NMR, 1 H 1 H COSY, 13 C NMR, 13 C 1 H HETCOR and mass spectrometry) methods.
