摘要
用可降解淀粉微球吸附薄荷油制得了包合物,建立了包合物中薄荷油的快速测定方法———紫外分光光度法。测定了吸附时间和投油量对饱和吸附量的影响。结果表明:该方法快速、准确、重复性好、操作简便。吸附2 h,薄荷油体积分数为4%时,饱和吸附量84.74μL/g淀粉微球。
A quick, stability, precise and convenient ultraviolet spectrophotometric method was developed to assay the concentration of peppermint oil in a compound, in which, peppermint oil was adsorbed by degradable starch microspheres （DSMs）. Furthermore, the effect of absorption time and the peppermint oil concentration on the saturated adsorption quantity of DSMs were investigated A high saturated adsorption quantity of DSMs （84.74 μL/g） was achieved when the concentration of peppermint oil was 4 % and the adsorption time was 2 h.
