Embodiment 1
[0029] The method for cyclically extracting sinomenine hydrochloride from S. chinensis of the present embodiment comprises the following steps:
[0030] (1) Get 600g of raw material coarse powder of Teng chinensis, add 600ml of 0.3mol / L HCL solution to infiltrate for 2 hours, put into 4 interconnected percolation cylinders in equal amounts respectively, then add 0.3mol / L of HCl to make each Exhaust the cylinder and fill it with hydrochloric acid solution, connect each percolation cylinder, and soak for 12 hours;
[0031] (2) Use 0.3mol / L HCL solution as the percolation liquid, open the top liquid inlet of the first-stage percolation cylinder, and start from the first-stage percolation cylinder at a rate of 8-10ml / min per kilogram of medicinal material Carry out continuous percolation operation, open the bottom liquid outlet of the fourth-stage percolation cylinder, and collect 1200ml of primary filtrate;
[0032] (3) After collecting the primary eluate of each percolation cyl...
Embodiment 2
[0036] The method for cyclically extracting sinomenine hydrochloride from S. chinensis of the present embodiment comprises the following steps:
[0037] (1) Take 600g of Qingfengteng coarse powder, add 600ml of 0.3mol / L HCL solution to infiltrate for 2 hours, put them into two percolation cylinders connected in series, and then add 0.3mol / L HCl to make each cylinder Exhaust and fill with hydrochloric acid solution, connect each percolation cylinder, and soak for 12 hours;
[0038] (2) Use 0.3mol / L HCL solution as the percolation liquid, open the top liquid inlet of the first-stage percolation cylinder, and start from the first-stage percolation cylinder at a rate of 8-10ml / min per kilogram of medicinal material Carry out continuous percolation operation, open the liquid outlet at the bottom of the second-stage percolation cylinder, and collect 1200ml of primary filtrate;
[0039] (3) After collecting the primary eluate of each percolation cylinder, close the top liquid inlet of...
