摘要：

Extraction of the timber of Khaya nyasica has given variable results. One sample has given nyasin, a new limonoid isomeric with khivorin, to which a structure is assigned. Another sample has given mainly khivorin, 11ß-acetoxy-khivorin and a number of minor constituents. Extraction of the seed has given the known limonoids khivorin, 3-deacetylkhivorin, and fissinolide, together with a new compound which appears to be the acetate of 3β-dihydrocarapin.
