Limonoids from Khaya ivorensis.
Four limonoids, 1-O-deacetyl-6-deoxykhayanolide E (1), 1-O-deacetyl-2 alpha-hydroxykhayanolide E (2), 3-acetyl-khayalactone (3), 11 alpha-acetoxy-2 alpha-hydroxy-6-deoxy-destigloylswietenine acetate (4), along with 12 known limonoids, were isolated from the stems of Khaya ivorensis. Their structures were elucidated on the basis of spectroscopic analysis.
