Abstract: |
|||
| A process for preparing matrine from sophocarpine by transhydrogenation includes such steps as dissolving sophocarpine in solvent (alcohol), adding hydrazine hydrate, oxidant and catalyst (or ultrasonic cocatalysis) or alkaline substance, reacting at 0-80 deg.C for 2-24 hr, extracting, drying, evaporating and crystallizing to obtain white matrine. Its advantages include simple process, high transform rate, and low energy consumption. | |||
