Two new sesquiterpenes, 8 alpha-(4-hydroxymethacryloyl)-14-acetoxy-salonitenolide (1) and 8 alpha-(2-hydroxymethyl 2-butenoyl)-14-acetoxy-salonitenolide (2), together with five known sesquiterpenes were isolated from the leaves of Vernonia nigritiana Oliv. & Hiern. Their structural characterization was obtained on the basis of extensive NMR spectroscopic and mass spectrometric studies.
