3、（high performance gel permeation chromatography-evaporative light scattering detector，HPGPC-ELSD）和超高效液相色谱-四极杆/静电场轨道阱高分辨质谱（ultra high performance liquid chromatography-quadrupole/electrostatic field orbit-trap high resolution mass spectrometr，UHPLC-Q-Orbitrap HRMS）等对黄芪和蜜炙黄芪的多糖、单糖、寡糖以及非糖小分子组分进行分析。结果 黄
4、芪和蜜炙黄芪中均可以找到 3 种相对分子质量的多糖，但 3 种多糖的重均相对分子质量、相对分子质量分布以及 3 种多糖各自的占比存在差异。黄芪和蜜炙黄芪多糖均含有甘露糖、鼠李糖、半乳糖醛酸、葡萄糖、半乳糖、阿拉伯糖、岩藻糖 7 种单糖，但两者物质的量比稍有不同（黄芪 vs 蜜炙黄芪0.700.200.855.670.442.040.32 vs 0.790.150.737.100.311.710.35）。在黄芪和蜜炙黄芪中均能检测到寡糖蔗糖，蜜炙后蔗糖含量显著下降（P0.01）。黄芪和蜜炙黄芪均含有游离单糖果糖、甘露糖、葡萄糖、半乳糖醛酸和岩藻糖，蜜炙黄芪中的果糖、甘露糖、葡萄糖含量均显著高于黄
5、芪（P0.05、0.01），而半乳糖醛酸的含量显著低于黄芪（P0.05），岩藻糖含量在黄芪蜜炙后无显著变化。从黄芪和蜜炙黄芪中共筛选出 20 个差异性非糖小分子成分，主要为皂苷类和黄酮类成分。代表性成分定量分析表明，与黄芪相比，蜜炙黄芪中的黄酮类成分毛蕊异黄酮葡萄糖苷、芒柄花素、芒柄花苷的含量显著降低（P0.05、0.01），皂苷类成分黄芪甲苷含量显著增加（P0.01）。呋喃醛衍生物 5-羟甲基糠醛在黄芪中未检测到，在蜜炙黄芪中的含量显著升高（P0.001）。结论 黄芪和蜜炙黄芪的糖类组分与非糖类组分存在显著差异，这可能是造成黄芪蜜炙后补中益气功效增强的主要原因。关键词：黄芪；蜜炙黄芪；代谢组
