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.
