The genus Euphorbia contains over 2000 species which exhibit a considerable diversity of di- and triterpenes in their latex. The North American species Euphorbia polygonifolia is a low growing plant of Atlantic and Great Lake beaches. The composition of its free and esterified triterpene alcohols was determined by HPLC and (1) H-NMR analyses. An unreported triterpene alcohol was found as 2.6% and 10.3% of the free and esterified fractions, respectively. The structure of the new triterpene alcohol was determined using HMBC, and its configurational assignment was secured by acid-catalyzed isomerization to isotirucallol. The new compound, polygonifoliol, was shown to be Δ(12) -isotirucallol.
