丹参醇提工艺中丹参酮Ⅱ_A降解动力学研究

Study on Degradation Dynamics of Tanshinone Ⅱ_A in Alcohol-Extract of Radix Salviae Miltiorrhizae during Evaporating,Concentrating and Drying Processes

采用薄层扫描法，以丹参酮ⅡA为检测指标，考察丹参醇提液在回收乙醇、浓缩、干燥工序中的化学动力学降解过程。实验结果表明，丹参醇提液在后处理工序的热不稳定性，是影响丹参酮ⅡA含量的主要因素。

The studies of degradation dynamics on tanshin0ne ⅡA of alc0hol extract of Radix Sa1viae Miltiorrhizae during the alcohol-recovery,concentrating and drying processes have been carried out by TLC-scanning method in an index of tanshinone ⅡA. The results indicated that it was the main factor that thermal unstabi1ity of alcohol extract during after-management processes influnced tanshinone,ⅡA content.
