目的 建立中草药浸提过程的温度与有效成分浸出浓度之间关系的数学模型。方法 在前文提出的中草药浸提过程动力学模型的基础上 ,进一步研究扩散系数和浓度梯度随温度的变化。结果 对不同温度下从丹参Salvia miltiorrhiza Bge.中浸提有效成分丹参酮 (tanshinone)的实验表明 ,该模型能满意地反映实验事实。结论 本工作建立的模型能描述温度与有效成分浸出浓度之间的关系。

Object To develop a mathematical model on the relationship between the temperature used in the course of extraction of medicinal herbs and the concentration of active component obtained. Methods Based on the kinetic model on medicinal herb extraction process reported in our previous article*, diffusion coefficient and concentration gradient varying with temperature were further studied. Results The process which tanshinone was extracted from Salvia miltiorrhiza Bge. at different temperatures showed that the model could well match the experimental data.Conclusion The relation between the temperature and the concentration of active component could be described by this model.
