摘    要:采用反相高效液相色谱法测定落叶松中二氢槲皮素的含量。确定色谱条件为:色谱柱Hypersil ODS—C18(4.6mm×200mm,5μm);流动相为V(甲酵):V(水):V(冰醋酸)=40:59:1;流速为1.0mL·min^-1;检测波长为288nm;柱温为28℃。在此条件下,二氢槲皮素与其它组分得到良好的分离。线性范围为0.02~0.2μg·μL^-1(r=0.9998),精密度RSD为0.96%(n=5),平均回收率为100.4%。

关 键 词:落叶松  二氢槲皮素  反相高效液相色谱法

Abstract:The method of determination dihydroquercetin in Larch by HPLC was established in this thesis.The following HPLC conditions are the best:column:Hypersil ODS-C18 (4.6 mm×200 mm,5μm);mobile phase : V (methanol) : V (water) : V(glacial acetica acid)= 40 : 59 : 1,flow rate: 1.0 mL·min^-1;detection wavelength:288 nm;temperature: 28℃ .Dihydroquercetin separated thoroughly from other components on this condition,the linearity of Dihydroquercetin was obtained within the range of 0.02 μg·μL^-1 (r=-0.9998), the average recovery was 100.4% with relative standard deviations of 0.96 %.
Keywords:Larch  taxifolin  reversed-phase high performance lquid chromatography (RP-HPLC)
