目的:建立中药材吸水膨胀动力学数学模型及对大黄进行研究;方法:用动力学方法建立中药材吸水膨胀动力学数学模型,用余水法测定不同时间大黄药材吸水量,并用残数法对数据进行曲线拟合,其拟合优度采用方差分析,以确定大黄药材的吸水动力学模型,再进一步计算各动力学参数.结果:中药材吸水膨胀遵循多元一级线性乳突模型,大黄药材吸水膨胀的动力学模型为三室,α=0.3241min-1,β=0.0185min-1,π=5.659×10-3 min-1,V∞T=1.726mL·g-1,V∞1=1.008mL·g-1,V∞2=0.2814mL·g-1,V∞3=0.4366mL·g-1,K=0 2186min-1,K12=0.02426min,K21=0.07422min-1,K1.3=6.402×10-3min-1,K31=0.02481min-1.结论:中药材吸水...

AIM: To establish a new kinetic model of hydrating swelling and to make experiments of Radix et Rhizoma Rhei (Rhubarb) designed to validate this model. METHODS: The model was set up according to kinetics, residul water analysis was adopted to measure Rhubarb's sakage, and then obtained the fittin curve and kinetic parameters, its goodness of fit was evaluated by analysis of variance. RESULTS: Hydrating swelling model of the vegetable herb had a form of multivariate first order linear differential equation. Rhubarb comformed to three compartment...
