Four glucosides of p-hydroxyphenyl derivatives from birch leaves

Abstract

The extractive of shirakamba (Betula platyphylla Sukatchev var. japonica Hara) leaves was investigated. Four glucosides of p-hydroxyphenyl derivatives were isolated, and their structures were indentified as betuloside (I), 3,4′-dihydroxy-propiophenone-3-β-D-glucopyranoside (II), salidroside (III), and arbutin (IV). Arbutin was newly found in the leaves of shirakamba. © The Japan Wood Research Society 1999.
