Four new phenolic glycosides from Polygala tenuifolia

Article abstract of DOI:10.1248/cpb.39.2600

Four new phenolic glycosides, tenuifolisides A (1), B (2), C (3), and D (4) together with a known phenolic glycoside, β-D-(3-O-sinapoyl)-fructofuranosyl-α-D-(6-O-sinapoyl)-glucopyranoside (5) were isolated from the roots of Polygala tenuifolia. The structures of these new compounds were characterized as β-D-[3-O-(3,4,5-trimethoxycinnamoyl)]fructofuranosyl-α-D-[6-O-(p-hydr oxybenzoyl)]-glucopyranoside (1), β-D-(3-O-sinapoyl)-fructofuranosyl-α-D-[6-O-(p-hydroxybenzoyl)]-gluco pyranoside (2), β-D-[3-O-(3,4,5-trimethoxycinnamoyl)]-fructofuranosyl-α-D-(6-O-sinapo yl)glucopyranoside (3), and 1,5-anhydro-[6-O-(3,4,5-trimethoxycinnamoyl)]-D-glucitol (4), respectively, on the basis of chemical and spectral evidence including two dimensional nuclear magnetic resonance (2D-NMR) studies.
