Abstract
Phenolic components in the plant were investigated to give phyllodulcin, phyllodulcin-8-0-β-D-glucoside, hydrangenol, umbelliferone, p-hydroxybenzoic acid, protocatechuic acid, gallic acid, methyl chlorogenate, chlorogenic acid, kaempferol, quercetin, isoquercitrin, rutin and three new components, hydrangea glucosides A, B, and C. On the basis of chemical and spectral data hydrangea glucosides A (I), B (II), and C (III) were characterized to 2-[β-(4'-hydroxyphenyl)-β-hydroxyethyl]-6-hydroxybenzoic acid-6-0-β-D-glucopyranoside, 2-[β-(4'-hydroxyphenyl)-β-hydroxyethyl]-6-hydroxybenzoic acid-β-O-β-D-glucoside and p-hydroxybenzaldehyde-O-β-D-glucopyranoside, respectively.
