New acylated salicin bis-glucosides from Viburnum veitchii.

The phytochemical study of aerial parts of Viburnum veitchii C.H. Wright, a deciduous species originary of Central China, led to the isolation of three salicin derivative bis-glucosides, i.e. henryoside (1), and the new structures 2'b-acetyl-3'b-(3-methylbutyryl)-henryoside (2) and 2'b,6'b-diacetyl-3'b-(3-methylbutyryl)-henryoside (3). In addition, luteolin, lonicerin, robustaflavone and eugenyl-β-D-glucopyranoside were also isolated.
