Chemical investigation of ceylonese plants part 27 extractives of calophyllum cuneifolium and calophyllum soulattri guttiferae



Chemical investigation of ceylonese plants part 27 extractives of calophyllum cuneifolium and calophyllum soulattri guttiferae



Journal of the Chemical Society Perkin Transactions I (13): 1505-1511



The bark and timber extractives of C. cuneifolium Thw. and C. soulattri Burm. f. were studied. The bark extract of C. cuneifolium Thw. yielded calabaxanthone, trapezifolixanthone, taraxerol, simiarenol, friedelin, and a solid bark acid identified as isoapetalic acid. The timber extract yielded 1,3,5-trihydroxy-2-(3-methyl-but-2-enyl)xanthone, 6 known xanthones and .beta.-sitosterol. The bark extract of C. soulattri Burm f. gave a new coumarin alcohol, soulattrolide, taraxerol, taraxerone and .beta.-sitosterol. The timber extract afforded 4 known xanthones and the trihydroxyxanthone.
