Structures of limonoids isolated from Carapa guianensis and their semi-synthetic derivatives. 6α-acetoxyepoxyazadiradione (1), andirobin (2), 6α-acetoxygedunin (3) and 7-deacetoxy-7-oxogedunin (4) were isolated herein from the residual seed material of C. guianensis. Semi-synthetic derivative 6α-hydroxydeacetylgedunin (5) was prepared herein. Gedunin (6), andirolide H (7), 6α-hydroxygedunin (8), 7-deacetylgedunin (9) and 7-deacetyl-7-O-methylgedunin (10) were reported by others as indicated in the text.
