Abstract
The title compound, formula C15H20O2, is orthorhombic, P2(1)2(1)2(1) w ith a = 8.747(2), b = 12.025(3), c = 12.554(3)Angstrom, Z = 4, and D-m = 1.32(2)g/ml. The structural analysis shows that the compound corres ponds to eudesma-4(15),7(11)-dien-8 alpha, 12-olide, a sesquiterpene l actone previously isolated from Aster umbellatus but whose crystal str ucture was unknown.
