Abstract

A new oleanane-type triterpenoid saponin with a carbonyl group at C-15, named polybosaponin A (1), together with a known triterpenoid saponin, dehydrosoyasaponin I (2), were isolated from Radix Hedysari. On the basis of one- and two-dimensional NMR and high resolution electrospray ionization mass spectrometry, the structure of 1 were elucidated and the ¹H and ¹³C NMR spectral signals were assigned totally. In addition, the complete assignment of ¹H NMR signals and revision of incorrect assignment of ¹³C NMR signals for 2 were also achieved based on one- and two-dimensional NMR spectrometry.
