Embodiment 1

[0038] 1. Take the dried fleshy stem of Cistanche tubulosa from which impurities have been removed, cut into small pieces, and pulverize through a sieve with an aperture of 840 μm as a raw material for processing;

[0039] 2. Use ethanol with a concentration of 70% as a solvent, and use 18 times the weight of the processed raw material of Cistanche to extract the processed raw material of Cistanche under reflux for 2 hours, and then use 8 times the amount of 70% ethanol for reflux extraction twice, each time for 1 hour;

[0040] 3. Combine the above extracts, concentrate under reduced pressure to a relative density of 1.08, put them in a centrifuge and centrifuge at 5000 rpm for 0.3 hours, and collect the supernatant;

[0041] 4. Filtrate through a microfiltration alumina ceramic membrane with a pore size of 0.25 μm, operate at a pressure of 0.3 MPa, and a temperature of 25 ° C to remove sub-particles, particles, flocculent precipitates and most microorganisms;

[0042] 5. Fil...

Embodiment 2

[0046] 1. Take the dried saline Cistanche fleshy stems removed from impurities, and crush them through a 420 μm aperture sieve;

[0047] 2. Use water as the solvent, and use 10 times the weight of the processed raw materials of Cistanche to extract the processed raw materials of Cistanche by ultrasonic extraction for 40 minutes at an ultrasonic frequency of 20KHz, pour out the supernatant as the extraction solution, and then use 6 times the amount of solvent to repeat the extraction 2 times, 30 minutes each time;

[0048] 3. The extracts obtained in step 2 were combined, concentrated under reduced pressure to a relative density of 1.05, placed in a centrifuge at 3000 rpm, centrifuged for 0.5 hours, and the permeate was collected;

[0049] 4. Take the permeate from step 3 and filter it through a microfiltration alumina ceramic membrane with a pore size of 0.10 μm, operating at a pressure of 0.4 MPa and at a temperature of 20 °C;

[0050] 5. Take the permeate from step 4 and fi...

Description

technical field [0001] The invention relates to a raw material containing phenylethanol glycoside produced from Cistanche deserticola and a preparation method thereof, in particular to a raw material containing phenylethanol glycoside produced from Cistanche deserticola and a preparation method thereof. Background technique [0002] Herba Cistanches, a traditional Chinese medicine, is the dry fleshy stem with scaly leaves of Cistanche Hoffmg.Et Link, a plant of the genus Cistanche in the family Orobanchaceae. Efficacy, is a famous tonic Chinese medicine. It has the highest frequency of occurrence in the prescriptions for nourishing kidney and yang in the past dynasties, and its probability in anti-aging and anti-aging traditional Chinese medicine prescriptions is second only to ginseng, so it is also called "desert ginseng". Because of its definite curative effect, mild medicinal properties, nourishing but not harsh, and nourishing but not dry, Cistanche is widely used in C...
