| 摘 要： | 用单扫示波极谱法，青藤碱在0．1mol／LNa_2B_4O_7中有两个还原峰，峰P_1和P_2的电位分别为-1．45V和-1．67V（vs．SCE），峰P_1的峰电流与浓度在0．06～1．8mg／L和20～34．6mg／L范围内有线性关系，检测限为0.02mg／L，用以测定中药膏风藤克总生物碱的含量，结果令人满意．实验证明，青藤碱的电极反应过程为不可逆的四电子过程，并讨论了青藤碱对超氧阴离子自由基（O_2~-）的清除作用。

| Abstract: | By means of single sweep oscillopolarogrphy, Sinomenine shows two reduction waves and the peak potentials are - 1.45 V and -1.67 V (vs. SCE) respectively, using 0.1 mol/L Na_2B_4O_7 as base solution, the peak height of wave P_1 is proportional to the concentration in the range of 0.06-1.8 mg/L and 2.0-34.6 mg/L respectively. And the detection limit is 0.02 mg/L. It is employed for the determination of totol alkaloids in Sinumenium acutum (Thumb. ) Rehd. et Wils with satisfaction. The experimental results show that electrode reaction of Sinomenine is irreversible four-electron process. In addition, it is discussed that Sinomenine can scavenge superoxide anion radical produced by the auto-oxidati0n of Pyrogallol. |
