Abstract :
Trichilin B (2), a limonoid having an unprecedented highly rearranged ring system, along with biosynthetically correlated trichilin A (1), was isolated from Trichilia connaroides. The structures were elucidated by spectroscopic analysis. Compound 2 features a unique 9,17-oxygen bridge, while two unprecedented δ-lactone rings fused to rings A and B at C-5, C-9 and ring C at C-8, C-14. Their cytotoxic activities were also evaluated.
