Studies on Oligosaccharides. XIII. Oligosaccharides in Polygala senega and Structures of Glycosyl-1, 5-anhydro-D-glucitols

Abstract

Presence of 1, 5-anhydro-D-glucitol, a characteristic compound in Poligalaceae family, was found in Polygala senega var. latiforia in addition to arabinose, fructose, glucose, sucrose, melibiose, raffinose, and stachyose. Further, a new compound, 2-O-α-D-galactopyranosyl-1, 5-anhydro-D-glucitol, was identified, and 6-O-β-D-glucopyranosyl-1, 5-anhydro-D-glucitol was found for the first time in the natural product.
