Embodiment 1
[0072] The raw materials are 450g of salvia miltiorrhiza, 141g of notoginseng, 8g of balsamic oil, and 50g of safflower.
[0073] Extract the salvia miltiorrhiza and safflower with ethanol to obtain the ethanol extract of the salvia miltiorrhiza and safflower, filter the extract with gauze, and collect the filtrate. The filtrate was ultrafiltered with a cellulose diacetate membrane with a molecular weight cut-off of 6000, and the filtration method was cross-flow filtration. The operating conditions of the ultrafiltration process are: the pressure of the liquid inlet of the ultrafiltration is 0.1Mpa, and the pressure of the liquid outlet of the ultrafiltration is 0.5kPa lower than the pressure of the liquid inlet. In the initial stage of ultrafiltration, a lower pressure is used, and then the pressure is gradually increased; in the process of ultrafiltration, periodic pressure fluctuations are used, and the pressure fluctuation difference is 0.1Mpa. The flow rate of the feed l...
Embodiment 2
[0076] The raw materials are 558g of Salvia miltiorrhiza, 34g of notoginseng, 8g of balsamic oil, and 72g of safflower.
[0077] Extracting the salvia miltiorrhiza and safflower with ethanol to obtain the ethanol extract of the salvia miltiorrhiza and safflower, performing microfiltration with a ceramic membrane, and collecting the filtrate. The filtrate was ultrafiltered with a polysulfone membrane with a molecular weight cut-off of 80,000, and the filtration method was dead-end filtration. The operating conditions of the ultrafiltration process are: the pressure of the liquid inlet of the ultrafiltration is 0.5Mpa, and the pressure of the liquid outlet of the ultrafiltration is 0.25kPa lower than the pressure of the liquid inlet. In the initial stage of ultrafiltration, a lower pressure is used, and then the pressure is gradually increased; in the process of ultrafiltration, periodic pressure fluctuations are adopted, and the pressure fluctuation difference is 0.2Mpa. The f...
Embodiment 3
[0080] The raw materials are 360g of Salvia miltiorrhiza, 232g of notoginseng, 8g of balm oil, and 24g of safflower.
[0081] Extracting Danshen, Panax notoginseng and safflower with ethanol to obtain a mixed ethanol extract, centrifuging the extract at high speed and then separating the supernatant. The liquid is ultrafiltered with a polysulfone membrane with a molecular weight cut-off of 50,000, and the filtration method adopts cross-flow filtration. The operating conditions of the ultrafiltration process are: the pressure of the liquid inlet of the ultrafiltration is 0.35Mpa, and the pressure of the liquid outlet of the ultrafiltration is 0.20kPa lower than the pressure of the liquid inlet. In the initial stage of ultrafiltration, a lower pressure is used, and then the pressure is gradually increased; in the process of ultrafiltration, periodic pressure fluctuations are adopted, and the pressure fluctuation difference is 0.2Mpa. The flow rate of the feed liquid is 3.0m / s. ...
