摘要Arillatanosides A-C are three triterpenoid saponins from Polygaln arillata Buch-Ham that have been reported previously, but with partially incorrect structures. Further investigation of their NMR data led to the conclusion that the terminal alpha-L-arabinopyranosyl unit originally proposed for Arillatanosides A-C (I-III) is actually a beta-n-xylopyranosyl unit. Thus, the correct structures of Arillatanosides A-C are represented by 1-3. Complete NMR assignments of Arillatanosides A-C (1-3) and the related polygalasaponin XXXV (4) were achieved using modern 2D NMR techniques, such as DQF H-H COSY, HMQC, HMBC, TOCSY, 2D HMQC-TOCSY.
