✦ Synopsis
A new sesquiterpene lactone, named potamopholide, was isolated along with the known triterpene lupeol from the leaves of Vernonia potamophila. The stereochemical structure of the new compound, (3R*,4S*,5E,8S*,10S*)-3,8epoxy-3,4,13-trihydroxy-1-oxogermacra-5,7(11)-dien-6,12olide, was elucidated by mass spectrometric (CIMS, EIMS, HREIMS) and NMR spectroscopic (HMQC, HMBC, NOESY)
