A straight-chain oligomeric structure composed of five secoisolariciresinoldiglucoside (SDG) residues interconnected by four 3-hydroxy-3-methyl glutaric acid (HMGA) residues (molecular weight ca. 4000 Da) was assigned to the main lignan of flaxseed o

A method was developed for the analysis of secoisolariciresinol diglucoside (SDG) in flaxseeds. The analytical method involves extraction of defatted flaxseed flour with dioxane/ethanol, aqueous base-hydrolysis, solid-phase purification of an SDG-con

A chemical investigation of the inner bark of Betula pubescens has led to the isolation of rhododendrin, epirhododendrin, apiosylrhododendrin and apiosylepirhododendrin. This is the first observation of both (+)- and (−)-rhododendrol glycosides in
