摘  要:采用高效液相色谱-二极管阵列检测器(HPLC-DAD)和火焰原子吸收光谱法(AAS),研究了玉屏风配伍黄芪:白术:防风1:1:1、2:2:1、3:1:1、4:4:1,及防风:黄芪1:2、黄芪:白术1:1、防风:白术1:2中黄芪甲苷在水提液和药渣乙醇提取液中的溶出率以及微量元素Cu、Zn、Fe、Mg、Ca的含量。结果表明:在整方中,黄芪甲苷的溶出率是黄芪:白术:防风1:1:1〉4:4:1〉3:1:1〉2:2:1;在拆方中,防风:黄芪〉黄芪:白术。在药渣乙醇提取液中的溶出率是水提液的0.58~6.77倍。微量元素的含量是Ca〉Mg〉Fe〉Cu〉Zn;在整方中,黄芪:白术:防风1:1:1的Cu、Mg含量高,4:4:1的Zn、Fe、Ca含量高;在拆方中,防风:黄芪的Cu、Zn含量高,黄芪:白术的Fe含量高,防风:白术的Ca、Mg含量高。在玉屏风药材配伍总质量不变而剂量变化中,黄芪甲苷的溶出率及微量元素的含量差异较大,其相关性比较复杂。The dissolution rate of astragaloside Ⅳ in water extraction and in herb residue ethanol extraction and the content of trace element Cu, Zn, Fe, Mg and Ca from Yupingfeng with different compatibility proportion (YPFdcp) of Radix Astragali (RA) : Rhizoma Atractylodes Macrocephale (RAM)=RadixSaposhnikoviae (RS) 1:1:1,2:2:1,3:1:1,4:4:1 and RS:RA 1:2,RA:RAM1:1,RS: RAM1:2 were studied by high performance liquid chromatography-diode array detector (HPLC-DAD) and flame atomic absorption spectrophotometry(AAS). All the results from these studies demonstrate that the dissolution rate of astragalosides Ⅳ in YPFdcp (RA:RAM:RS) were in the order: 1:1:1〉4: 4:1〉3:1:1〉2:2:1 in the intact recipes; the dissolution rate of astragalosides Ⅳ in RS:RA was larger than that in RA: RAM in the separated recipes; and the dissolution rates of astragalosided Ⅳ in ethanol extract were 0.58-6.77 times of that in water extract. The content order of tract elements was Ca〉 Mg〉Fe〉Cu〉Zn. The contents ofCuandMginRA:AMK:RS1:1:1 and Zn , Fe and Ca in RA: RAM :RS 4:4:1 were higher in the intact recipes. In the separated recipes, the contents of Cu and Zn in RS:RA,Fe in RA: AMK and Ca and Mg in RS: AMK were higher. As the dosage of Yupingfeng changed, the dissolution rate of astragaloside Ⅳ in water or ethanol and the contents of trace elements also changed obviously, and the relativity of change was rather complicated.
