Furostanol saponins from the fresh rhizomes of Polygonatum kingianum

Chem Pharm Bull (Tokyo). 2006 Jul;54(7):931-5. doi: 10.1248/cpb.54.931.

Abstract

Ten furostanol saponins were isolated as five pairs of 25R and 25S epimers from the fresh rhizomes of Polygonatum kingianum. Seven of them were identified as new compounds, (25S)-kingianoside D (2), (25S)-kingiano-side C (4), (25R,22)-hydroxylwattinoside C (5), kingianoside E (7), (25S)-kingianoside E (8), kingianoside F (9) and (25S)-kingianoside F (10), together with three known saponins, kingianoside C (1), kingianoside D (3), and 22-hydroxylwattinoside C (6). The structures of the new saponins were determinded by detailed analysis of their 1D and 2D NMR spectra, and by comparison of the spectral data with those reported.
