摘要
目的对枸杞酒中6种矿物质元素Ca,Mg,Fe,Zn,Mn和Cu的溶出规律进行研究。方法采用传统药酒泡制方法配制枸杞酒,高压密封消解法消解样品,火焰原子吸收光谱法(FAAS)和石墨炉原子吸收光谱法(GFAAS)检测。结果枸杞酒泡制过程中Ca,Mg,Fe,Zn,Mn,Cu含量随浸泡时间的溶出动力学方程回归关系极显著(P<0.01),Mg、Fe溶出速度快,15 d时就已达到溶出平衡点,其它元素在30 d内还未达到溶出最大量。从药酒中各元素的溶出率来看,30d时累积溶出率以Cu最高(65.93%),其次为Fe(58.29%)、Mg(47.11%)和Zn(42.61%),Ca(19.88%)和Mn(17.62%)的累积溶出率都较低。结论枸杞酒中6种矿物质元素溶出规律明显,可用于从矿物质元素角度理解枸杞酒中的化学组成和安全功效性及为药酒的日常饮用提供参考。
Objective To study the dissolution characteristics of six kinds of mineral elements. Methods Traditional technology was adopted to produce medicinal liquor. The FAAS and GFAAS combined with pressurized sample digestion were applied to de-termine the contents of mineral elements in Fructus Lycii medicinal liquor. Results The dissolution kinetics regression equations were desirable （P 〈0.01 ）, and the solubility of magnesium, iron, copper, calcium, manganese and zinc had obvious differences, with a quick dissolution rate for Mg, Fe, which reached the equilibrium point for 15 days, while other elements did not achieve the highest dissolution contents even for 30 days. From the aspect of dissolution rates of minerals in wine, the accumulated dissolution rate of Cu was the highest （65.93%）, followed by Fe （58.29%）, Mg （47.11%）, Zn （42.61%）, and that of Ca （ 19.88% ） and Mn （ 17.62% ） were relatively low after 30 days. Conclusion The dissolution properties of six kinds of minerals are clear, and the dissolution curves and the accumulative dissolution rates of minerals in Fructus Lycii medicinal liquor wine reflect the solubility characteristics of various minerals in the liquor, which can be used to understand the composition, safety and efficacy of the medical liquor and advise people about the use of medical liquor from the perspective of mineral elements.
