结果：确定最佳制备工艺为：人参粉碎成细粉，黄连、大黄分别用乙醇提取，黄芪、水蛭、猪苓三药用水共煎，各提取物干浸膏细粉与人参细粉混匀，装胶囊；有效成分含量的控制标准为：每粒胶囊中含人参皂苷〓不低于0.235mg；人参、黄连是六味糖肾胶囊发挥降糖作用的主要药味；六味糖肾胶囊中小檗碱在动物体内的分布和消除速度均较适中，但病理模型动物与正常动物相比吸收较差。

The results calculated by the Elovich rate equation showed that K release rates from 1 mol.L-1 HNO3 extraction ＞those from 2 mol.L-1 HNO3 extraction ＞those from H-resin extraction. Elovich equations combining with the data of H-resin and 2 mol.L-1 HNO3 successive extraction could well described the release characteristics of soil K. The correlation coefficients of the equations reached most significant levels (r＝0.956**—0.999**), and standard errors of specific K release capacities between the vaules calculated by the equations and those measured by both successive extractions were smaller(s=1.61 and 3.52). The specific release rates of soil K calculated by the Elovich rate equations were significantly correlated with the indices of soil K availability (the amounts of easily available K, nonexchangeable K, total available K in soils and K absorbed by ryegrass).

研究结果表明：1 mol.L-1 HNO3提取法的释K速率＞2 mol.L-1 HNO3提取法的释K速率＞氢饱和交换树脂提取法的释K速率；氢质交换树脂和2 mol.L-1 HNO3提取法结合Elovich模型较理想地描述了土壤K素的释放特性，拟合方程的相关系数均达极显著水平(r＝0.956**-0.999**)，土壤特征累积释K量的计算值与实测值的标准差较小(s=1.61和3.52)，且通过速率方程计算的土壤特征释K速率与K素有效性指标(速效K、缓效 K、有效K及黑麦草总吸K量)的相关性也较为密切。
