为了研究槲皮素的生物学效应,需要槲皮素代谢的真实产物作为标准。因此描述了硫酸槲皮素标准品的合成。使槲皮素与10倍摩尔过量的三氧化硫-N-三乙胺反应,并通过HPLC和质谱分析产物。鉴定出四个单硫酸盐和三个二硫酸盐,并通过HPLC峰分离物的1H NMR光谱分析得出结构推断。分析接受槲皮素(1.9 g / kg po)的大鼠的尿液产生一个峰,与槲皮素和三氧化硫-N-三乙胺之间的反应产物相比,该峰被鉴定为槲皮素3'-O-硫酸盐。

A process for producing esters wherein a carboxylic acid is reacted with an alcohol in the presence of a hydrolyzable catalyst in an aqueous medium under mixing to produce a reaction mixture comprising an organic phase containing ester and an aqueous phase.
The invention relates to phenoxy derivatives with glycosidically bound sugar moieties, pharmaceutical compositions containing such compounds, uses of such compounds and compositions, and methods of making such compounds and pharmaceutical compositions.
Three of these compounds were further isolated, and their structures were elucidated by mass spectrometry and 1H and 13C nuclearmagneticresonance using one- and two-dimensional techniques (heteronuclear single-quantum coherence and heteronuclear multiple-bond correlation). The calculation of the proton and carbon shifts caused by sulfation allowed for the assignment of the position of the sulfate
