Embodiment 1
[0145] Embodiment 1. Preparation of glyoxal complex
[0146] Material ratio: Glacial acetic acid 900kg: copper sulfate 135kg: sodium chloride 100kg: glyoxal 30kg: N-(2,3-dimethoxy-N-benzyl)-β-(3,4-dimethoxy phenyl) ethylamine sulfate (or inorganic salts such as hydrochloride) 100kg
[0147] Weigh 900kg of glacial acetic acid, 135kg of copper chloride and 30kg of glyoxal, stir and mix them in the reaction kettle, heat up, and control the temperature at 70°C. After fully stirring for 45min, the aldehyde-copper complex is obtained.
Embodiment 2
[0148] Embodiment 2. Preparation of palmatine complex
[0149] Get glacial acetic acid 900kg, cupric chloride 135kg, embodiment 1. The aldehyde copper complex and N-(2,3-dimethoxy-N-benzyl)-β-(3,4-dimethoxy 100kg of phenyl)ethylamine hydrochloride was stirred and mixed in a reaction kettle, and the temperature was raised to control the temperature at 95°C. After stirring for 4 hours, the temperature was lowered, and the solvent was removed to obtain the palmatine complex.
Embodiment 3
[0150] Embodiment 3. Preparation of Palmatine
[0151] Take the palmatine complex compound of Example 2, add 1000kg of water, stir and mix, heat up to 90°C, add saturated sodium carbonate solution, adjust the pH value to 8.0, filter while it is hot, collect the filtrate, cool the filtrate, and crystallize. The crystal form is needle-like crystal or granular crystal, and the color is light yellow to dark yellow. After cooling down and filtering, 90kg of palmatine (molecular formula: C 21 h 21 NO 4 or C 21 h 21 NO 4 ·3H 2 O).
