| Abstract: |
| Researching some active substance in nature plant using oscillating is a new field.The experimental results of Dictamnus dasycarpus Turcz-KBrO3-Mn2+-H2SO4-acetone oscillating system in the presence of Mn2+ as catalyst are reported.The effects of different concentrations of components on the oscillatory induction period,oscillatory period and oscillating waves are also studied.Based on the experiments,the apparent activation energy and the kinetic equations were obtained.Then reaction mechanism and mutagenic activity of dictamnine was studied preliminarily.It is confirmed that dictamnine in oscillating reaction plays a important role. |
