spirostanol glycoside/polygonatum

Investigation of the roots of Polygonatum prattii afforded three new steroid glycosides, paratiosides A-C, and three new prosapogenins, pratiosides D1, E1 and F1. The latter three, which were obtained from the enzymatic hydrolysis products of a glycoside mixture, are considered to be the

Four new steroidal saponins, named neosibiricosides A-D (1-4), were isolated from the rhizomes of Polygonatum sibiricum, along with two known spirostanol glycosides. The structures of the new glycosides were elucidated by spectroscopic methods and acid hydrolysis as

An HPLC/ESI/MS method has been developed to identify and quantify the spirostanol glycosides in the rhizomes of five Polygonatum species. The relative distribution of two steroidal saponins in each extract was established using the selective ion monitoring (SIM) mode via an electrospray ionization
