Abstract

Seven rings A,B‐seco limonoids 1–7 were isolated from the EtOH extract of the seed of Aphanamixis polystachya. Their structures were identified as rohituka‐7 (1), dregeana‐1 (2), rohituka‐15 (3), Tr‐B (4), rohituka‐3 (5), rohituka‐5 (6), and rohituka‐14 (7) by MS and NMR spectroscopy. The complete assignment of proton and carbon signals was achieved by 1D and 2D NMR experiments including DEPT, HSQC, ^1^H^1^H COSY, HMBC, and NOESY. Copyright © 2006 John Wiley & Sons, Ltd.
