| 摘 要： | 用甲醇作提取溶剂,在回流条件下考察了从丹参药材中提取丹参酮类有效成分的过程中,隐丹参酮、丹参酮I及丹参酮IIA等三种丹参酮的热降解行为。结果表明,回流提取过程中所考察的三种丹参酮均发生严重的热降解,降解速率:丹参酮IIA>丹参酮I>隐丹参酮,其热降解均具有零级反应动力学特征;同时,回流提取过程中丹参酮的热降解是在丹参酮共萃物存在下发生的。 |

| Abstract: | Thermal degradation behavior of cryptotanshinone,tanshinone I and tanshinone IIA has been studied during the process of reflux extraction of tanshinones from Salvia miltiorrhiza Bge.with methanol as extracting solvent.The obtained results showed that the thermal degradation of cryptotanshinone,tanshinone I and tanshinone IIA occurred obviously during reflux extraction in the order of degradation rate:tanshinone IIA>tanshinone I>cryptotanshinone,and their thermal degradation was featured with zero order reaction;meanwhile,it was under the existence of other components coextracted with tanshinones that the thermal degradation of cryptotanshinone,tanshinone I and tanshinone IIA occurred. |
| Keywords: | thermal degradation tanshinones Salvia miltiorrhiza Bge reflux extraction |
