Complete assignments of 1H and 13C NMR data for rings A,B-seco limonoids from the seed of Aphanamixis polystachya.Magn Reson Chem. 2007 Feb; 45(2):189-92.MR
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, 1H--1H COSY, HMBC, and NOESY.
