B , ( - ) The result showed that the relations between lnC and lnt lnσor ln M R were linear when only one . , parameter was changed A case for extracting tanshinone from S al via m iltiorrh iz a Bge was sutdied the result indicated a perfect matching between the mathematical model and the experimental data. 　 　 　 　 Key words medicinal herb isothermal extraction process kinetic model tanshinone B B 　　,、 : dn /d t = D S (d C / )…( 1) , 。 dx B , , d CB /dx S 。 nB B 。 ,, ,D 。,
