Abstract:
Eight new limonoids with four different structural frameworks, including gedunin (1, 2), havanensin (3, 4), mexicanolide (5, 6), and methyl angolensate types (7, 8), together with six known limonoids, were isolated from the leaves of Cipadessa baccifera. Compounds 2 and 5 exhibited moderate cytotoxicity against the HL-60 cell line with an IC(50) value of 20 microM.
