Velutinalide C ( 4 ), a new polycyclic phragmalin limonoid featuring a C(15)–C(21) linkage and a C 4 unit at C(15), together with two known related compounds, chukfuransins C and D ( 2 and 3 , resp.), was isolated from the leaves of Chukrasia tabularis var. velutina. The structure of the new compound 4 was elucidated on the basis of extensive spectroscopic analyses and comparison with literature data.
