摘要： Three new limonoids named chuktabrin L (1), meliasenin Y (2), 11a-acetoxy-20,21,22,23-tetrahydro-23-oxoazadirone (3) and one new triterpenoid, named hispidol C (4), together with one known compound hispidol B (5) were isolated from the stems of Chukrasia tabularis A. Juss. Chuktabrin L (1) was a D-ring-opened 16-norphragmalin featuring a unique C-16 degraded polycyclic skeleton. Structures were elucidated by spectroscopic techniques of IR, HRESIMS and NMR. Compounds 1-5 were evaluated for acetylcholinesterase (AChE) inhibitory activity in vitro, however turned out inactive.
