Abstract
The bark and timber extractives of C. cuneifolium Thw. and C. soulattri Burm. f. have been studied. The bark extract of C. cuneifolium Thw. yielded calabaxanthone (1), trapezifolixanthone (2), taraxerol, simiarenol, friedelin, and a solid bark acid identified as isoapetalic acid (4a). The timber extract yielded 1,3,5-trihydroxy-2-(3-methylbut-2-enyl)xanthone (6a), six known xanthones, and β-sitosterol. The bark extract of C. soulattri Burm f. gave a new coumarin alcohol, soulattrolide (13a), taraxerol, taraxerone, and β-sitosterol. The timber extract afforded four known xanthones and the trihydroxyxanthone (6a).This publication has 2 references indexed in Scilit:
