摘要：

The sesquiterpene guayulin B, C23H30O3, 1, crystallizes with two independent molecules in monoclinic space group P2(1) with a = 18.099 (1), b = 6.0649(6), c = 19.126(1) Angstrom, beta = 100.82(1)degrees, V = 2062.1(5) Angstrom(3), and Z = 4. The double bonds of the cyclodecadiene ring are E, both methyl groups on the 10-membered ring are beta-oriented. The cyclopropane ring at C6 and C7 also has the beta orientation, while the anisoyloxy group is oriented oc. The 10-membered rings of the two independent molecules have the same conformation as that of guayulin A.
