Aromatic diglycosides from Cladogynos orientalis.
Two unusual aromatic diglycosides with galloyl substitution, 4''-O-galloyl-violutoside and 4''-O-galloyl-benzyl-O-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside, were isolated from the aerial portion of Cladogynos orientalis along with isovitexin, apigenin 6-C-(2''-O-galloyl)-beta-D-glucopyranoside, apigenin 8-C-(2''-O-galloyl)-beta-D-glucopyranoside, syringic acid beta-D-glucopyranoside, 3,4,5-trimethoxyphenyl beta-D-glucopyranoside, (6S,9R)-roseoside, and violutioside. The structural elucidations were based on analyses of chemical and spectroscopic data by including 1D and 2D NMR analyses.
