Embodiment 1
[0023] Grind the dried root of the golden silk horsetail, take 2kg, add 1.0% hydrochloric acid aqueous solution to soak for 4 hours, ultrasonic treatment for 40 minutes, filter the obtained extract on HZD-2 cation exchange resin, first wash it with deionized water until it is neutral, and then wash it with 8LpH10 85% ethanol solution for elution, the eluent was concentrated under reduced pressure, the pH was adjusted to 10.5, extracted with chloroform, the chloroform layer was taken, and the chloroform was recovered to dry to obtain the crude product; Mix at 7:2:10, let it stand, separate the upper and lower phases, the lower phase is the stationary phase, and the upper phase is the mobile phase, turn on the high-speed countercurrent chromatograph, adjust the speed to 850rpm, take the crude product dissolved in the upper phase and inject it into the chromatograph to control the flow The phase flow rate was 2ml / min, and the hylandrazine fraction was collected, concentrated, and ...
Embodiment 2
[0025] Grind the dried root of the golden horsetail, take 2kg, add 0.5% hydrochloric acid aqueous solution to soak for 3 hours, ultrasonically treat for 45 minutes, filter the obtained extract on D-151 cation exchange resin, wash it with deionized water until neutral, and then use 8LpH9 75% ethanol solution was eluted, the eluate was concentrated under reduced pressure, adjusted to pH 11.0, extracted with chloroform, the chloroform layer was taken, and the chloroform was recovered to dry to obtain the crude product; Mix for 6:1:8, let it stand, separate the upper and lower phases, the lower phase is the stationary phase, and the upper phase is the mobile phase, turn on the high-speed countercurrent chromatograph, adjust the speed to 850rpm, take the dissolved crude product of the upper phase and inject it into the chromatograph, and control the flow The phase flow rate was 2ml / min, and the hylandrazine fraction was collected, concentrated, and dried to obtain coarse crystals; d...
