丹参酮ⅡA在90℃水浴加热72h，降解产物经GC／MS分析，可检出烷烃等46种分解产物．推断该分解反应与丹参酮ⅡA在水中转化成酮类，发挥递氢体作用，促进氧化还原反应有关。
Tanshinone IIA was heated in a 90°C water bath for 72 h. The degradation products were analyzed by GC/MS and 46 decomposition products such as alkanes were detected. It is inferred that the decomposition reaction and conversion of tanshinone IIA into ketones in water play a role of the hydrogen donor and promote the redox reaction.
