Abstract
A hexane extract of the wood of Dysoxylum muelleri has yielded 3 alpha -cinnamoyl glabretal, 3 alpha-benzoyl glabretal, 21,24-epoxy-23 alpha, 25-dihydroxy-4 alpha,4 beta,8 beta-trimethyl-14,18-cyclo-5 alpha,13 al pha,14 alpha,17 alpha-cholestan-3 alpha-cinnamoyl-7 alpha-yl acetate, 21,24-epoxy,23 alpha,25-dihydroxy-4 alpha,4 beta,8 beta-trimethyl-14,1 8-cyclo-5 alpha,13 alpha,14 alpha,17 alpha-cholestan-3 alpha-benzoyl-7 alpha-yl acetate; 21,23-epoxy-21,24,25-trihydroxy-4 alpha,4 beta,8 be ta-trimethyl-14,18-cyclo-5 alpha,13 alpha,14 alpha,17 alpha-cholestan- 3 alpha-cinnamoyl-7 alpha-yl acetate and 21,23-epoxy-21,24,25-trihydro xy-4 alpha,4 beta,8 beta-trimethyl-14,18-cyclo-5 alpha,13 alpha,14 alp ha,17 alpha-cholestan-3 alpha-benzoyl-7 alpha-yl-acetate. A hexane ext ract of the bark yielded 6 alpha-acetoxy-obacunone acetate.
