Embodiment 1

[0047] Tetrahydropalmatine Derivatives Maleate

[0048] Dissolve 0.37 g (1 mmol) of the compound tetrahydropalmatine derivatives and 0.12 g (1 mmol) of maleic acid in 10 ml of boiling ethanol. The hot solution is filtered through diatomaceous earth, then slowly cooled under gentle stirring, and left to stand for several hours in a temperature environment of 0-5°C, and the maleate crystals of the derivatives of tetrahydropalmatine are precipitated, and the derivatives of tetrahydropalmatine are filtered out The maleate salt crystals were washed with cold ethanol and dried under vacuum at 50°C to yield 0.50 g of product.

Embodiment 2

[0050] Tetrahydropalmatine Derivatives Maleate

[0051] Stir 0.36 g of the compound tetrahydropalmatine derivative maleate and 0.12 g of maleic acid in 10 ml of refluxing ethanol until all the solids are dissolved. Add activated carbon, filter the hot solution through diatomaceous earth, and cool down to room temperature while stirring. Standing for several hours in a temperature environment of 0-5°C, the crystals of the maleic acid salt of the derivatives of tetrahydropalmatine are precipitated, the crystals of the maleic acid salt of the derivatives of tetrahydropalmatine are filtered out, washed with cold ethanol and placed under vacuum at 50°C Drying yielded 0.47 g of product.
