ABSTRACT
The title triterpene, D-friedoolean-14-en-3 beta-yl acetate, C32H52O2, was isolated from dichloromethane extracts of the roots of common ragweed Ambrosia artemisiifolia. The skeleton contains five fused six-membered rings with an average Csp3-Csp3 bond distance of 1.549 (6) A and one double bond of length 1.348 (6) A. The D and E rings are cis-fused. The compound also contains a beta-oriented acetate group with a C-O distance 1.461 (5) A.
