Embodiment 1
[0024] Select 10 kg of schisandra chinensis without insects and pollution, crush it to about 100 meshes; add 100 liters of 80% ethanol, stir and mix evenly for soaking; place it for 0.5h and then stir and mix evenly for later use; pump the soaked raw materials continuously into high In the voltage pulse extraction unit, the field strength is 10kv, the number of pulses is 10, and the extraction solution is continuously collected; the extraction solution is pumped into a plate and frame filter for filtration; the filtrate is vacuum concentrated to a liquid extract; the liquid extract is sprayed Dried or freeze-dried into powder, the yield of schisandrin A is 76g.
Embodiment 2
[0026] Crush 10kg of schisandra to 100 mesh, add 12 liters of 70% ethanol extraction solvent to soak; stir and mix the raw material with the extraction solvent, put it aside for 0.5h and then stir and mix well for later use; use a liquid pump to continuously pump the soaked raw material into the In the voltage pulse extraction unit, the field strength is 15kv and the number of pulses is 10, and the extraction solution is continuously collected; the extraction solution is pumped into a plate and frame filter for filtration; the filtrate is vacuum concentrated to a liquid extract; the liquid extract is sprayed Dried or freeze-dried into powder, the yield of schisandrin A is 80g.
Embodiment 3
[0028] Choose 10kg Schisandra chinensis and crush it to about 100 meshes; add the raw materials and 90% ethanol extraction solvent to soak according to material: liquid = 1:14; Continuously pump the soaked raw materials into the high-voltage pulse extraction unit, extract with the parameters of field strength 10kv and pulse number 12, and continuously collect the extract; pump the extract into the plate and frame filter for filtration; vacuum concentrate the filtrate to Fluid extract; the fluid extract is spray-dried or freeze-dried into powder, and the yield of schisandrin A is 85g.
