Embodiment 1

[0021] Example 1 High-purity breviscapine extract was prepared by dynamic ultrasonic countercurrent extraction combined with macroporous adsorption resin column chromatography and dynamic axial compression industrial preparation chromatographic separation technology

[0022] Crush 10 kg of Erigeron breviscapus to 20-30 meshes, add 8 times the amount of ethanol with a concentration of 70% by volume, extract continuously at a frequency of 30 kHz, and ultrasonic power 20 kW for 3 times, each time for 40 min, filter, and combine the extracts , recover the extraction solvent under reduced pressure, properly concentrate to a concentration of 0.6 g crude drug / ml, add 1 mol / L hydrochloric acid to adjust the pH value to 4, and pass through the HPD650 macroporous adsorption resin chromatography column at a flow rate of 2BV / h. The ratio of solid matter to dry resin is 1:6, and the ratio of diameter to height is 1:8. First wash the resin column bed with 4 BV of distilled water, and the elu...

Embodiment 2

[0023] Example 2 Preparation of High Purity Breviscapine Extract by Heating Reflux Extraction Combined with Macroporous Adsorption Resin Column Chromatography and High Speed ​​Counter-Current Chromatography

[0024] Add 15 times the amount of ethanol with a volume percentage concentration of 80% to 2 kg of Erigeron breviscapus crushed to 20-30 mesh, heat and reflux for extraction 3 times, each time for 1.5 h, filter, combine the extracts, and concentrate to a concentration of 1.0 g Crude drug / ml, after filtering, add 1mol / L hydrochloric acid to adjust the pH value to 4-5, and pass through the HPD400 macroporous adsorption resin chromatography column at a flow rate of 3BV / h. The ratio of the sample solution to the dry resin is 1: 8. The diameter-to-height ratio is 1:10. First wash the resin with 6 BV of water, the elution flow rate is 4 BV / h, discard the water eluent; then elute with methanol with a concentration of 60% by volume. The flow rate is 3 BV / h, the eluent is decompre...

Embodiment 3

[0025] Example 3 Preparation of high-purity breviscapine extract by heating reflux extraction combined with macroporous adsorption resin column chromatography and dynamic axial compression industrial preparation chromatographic separation technology

[0026] 5 kg of Asarum breviscapus was moderately crushed, and 10 times the amount of 60% methanol was added, and the frequency was 30 kHz, the ultrasonic power was 20 kW, and the ultrasonic power was continuously ultrasonically countercurrently extracted 3 times, each time for 0.5 h, filtered, combined extracts, methanol was recovered under reduced pressure, and water was added to adjust Concentration to 1.5 g crude drug / ml, add 1 mol / L hydrochloric acid to adjust the pH value to 6, pass through the SP825 macroporous adsorption resin chromatography column twice at a flow rate of 2BV / h, and load the sample solution according to the ratio of solid content to dry resin 1:9, the ratio of diameter to height is 1:8, wash the resin with ...

Abstract

The invention provides a preparation method for high-purity breviscapine extract as well as preparations and application thereof. The method disclosed by the invention comprises the following steps: taking erigeron breviscapus as a raw material, performing dynamic ultrasonic countercurrent extraction or heating reflux extraction, filtering, centrifuging, adjusting the pH value to 2.0-7.0, performing macroporous resin column chromatography, preparing by using dynamic axial compression industrial chromatographic separation, or preparing by adopting high-speed counter-current chromatography, freezing or performing spray drying, thereby obtaining the high-purity breviscapine extract. According to the method disclosed by the invention, extraction can be completed in a short time at a low temperature, the separation cycle is short, the efficiency is high, the occupied volume for extraction is reduced, the production cost is lowered, the energy consumption and environmental pollution can be reduced, and the purity of the obtained breviscapine can be 95% or higher. Added with various added pharmaceutical adjuvants, the high-purity breviscapine extract can be prepared into ordinary tablets, thin membrane coated tablets, capsules, dispersible tablets, dropping pills, granules, sustained-release preparations and other solid oral preparations, as well as spray, aerosol, lyophilized powder for injection and injection, and the preparations can be used for treating cardiovascular and cerebrovascular diseases and are obvious in curative effects, safe and reliable.
