Embodiment 1
[0054] Example 1: Preparation process of total tanshinone and total phenolic acid extract of Salvia miltiorrhiza
[0055] Take 1kg of Danshen decoction pieces, extract 3 times with 10L of 90% ethanol under reflux, extract for 2 hours each time, recover the solvent under reduced pressure, and obtain the crude extract of total tanshinone; solvent to obtain the crude extract of total phenolic acids. The total tanshinone crude extract was dispersed and dissolved by adding 50% ethanol to make the solution concentration 0.70 mg / mL (calculated by the total tanshinone amount), and the ultrasonic wave was used to dissolve and disperse evenly. The suspension was taken and passed through 1.8L AB-8 macroporous adsorption resin. The adsorption flow rate is 1.0mL / min, the diameter-to-height ratio of the resin column is 1:6, the sample loading is 2.1mg / mL (in terms of total tanshinone), and after washing 3 times the volume of the resin, 70% ethanol is used to elute 7 times the volume of the ...
Embodiment 2
[0056] Example 2: Preparation process of total tanshinone and total phenolic acid extract of Salvia miltiorrhiza
[0057] Take 2 kg of Danshen decoction pieces, extract 3 times with 15 L of 95% ethanol under reflux, extract 1.5 hours each time, recover the solvent under reduced pressure, and obtain the crude extract of total tanshinone; extract the dregs with 10 L of 5% ethanol under reflux three times, extract 1 hour each time, The solvent was recovered under reduced pressure to obtain a crude extract of total phenolic acids. The total tanshinone crude extract was dispersed and dissolved by adding 45% ethanol to make the solution concentration 0.60 mg / mL (calculated by the amount of total tanshinone). Ultrasound was used to dissolve and disperse evenly. The suspension was taken and passed through 3L AB-8 macroporous adsorption resin for adsorption The flow rate is 1.0mL / min, the diameter-to-height ratio of the resin column is 1:6, the sample loading is 1.8mg / mL (based on the ...
Embodiment 3
[0058] Example 3: Preparation process of total tanshinone and total phenolic acid extract of Salvia miltiorrhiza
[0059] Take 5kg of Danshen decoction pieces, extract 3 times with 10L of 90% ethanol under reflux, extract for 1 hour each time, recover the solvent under reduced pressure, and obtain the crude extract of total tanshinone; solvent to obtain the crude extract of total phenolic acids. The total tanshinone crude extract is dispersed and dissolved by adding 50% ethanol to make the solution concentration 0.64mg / mL (calculated by the amount of total tanshinone), ultrasonically dissolves and disperses evenly, takes the suspension, passes through 2L AB-8 macroporous adsorption resin, and absorbs The flow rate is 1.0mL / min, the diameter-to-height ratio of the resin column is 1:6, the sample loading is 2.0mg / mL (based on the amount of total tanshinone), wash with water for 3 times the volume of the resin, and then elute with 70% ethanol for 8 times the volume of the resin f...
