Embodiment 1
[0015] (1) Maca dried fruit is soaked in water until there is no hard core, and treated with a colloid mill to obtain a slurry, preheat the slurry to 50°C, adjust the pH with 1mol / L HCL and 1mol / L NaOH to make it at 5, add 3000U / L kg of cellulase to break the cell wall, dissolve the active substance inside, enzymatically hydrolyze for 4h, then inactivate the enzyme at 100°C for 10min, centrifuge at 8000rn for 20min, and obtain the supernatant;
[0016] (2) the supernatant is filtered through a mixed cellulose coarse filter membrane with a pore size of 0.6um to obtain a crude filtrate;
[0017] (3) add the distilled water of 1.5 times of volumes of the crude filtrate in the crude filtrate, filter with the ultrafiltration membrane of molecular cut-off 50KD to remove enzyme and undecomposed macromolecules, obtain the ultrafiltrate;
[0018] (4) The ultrafiltrate was evaporated in vacuum at 50° C., and concentrated to 2% of the original volume to obtain a concentrated solution;

Embodiment 2
[0022] (1) Maca dried fruit is soaked in water until there is no hard core, and treated with a colloid mill to obtain a slurry, preheat the slurry to 50°C, adjust the pH with 1mol / L HCL and 1mol / L NaOH to make it at 4, add 2000U / L Kg of cellulase breaks the cell wall, dissolves the active substance inside, enzymatically hydrolyzes for 3 hours, then inactivates the enzyme at 100°C for 10 minutes, centrifuges at 8000rn for 20 minutes, and obtains the supernatant;
[0023] (2) the supernatant is filtered through a mixed cellulose coarse filter membrane with a pore size of 0.6um to obtain a crude filtrate;
[0024] (3) Add distilled water of 1 times the volume of the crude filtrate to the crude filtrate, and filter with an ultrafiltration membrane with a molecular cut-off of 50KD to remove enzymes and undecomposed macromolecules to obtain an ultrafiltrate;
[0025] (4) The ultrafiltrate was evaporated in vacuum at 40° C., and concentrated to 1% of the original volume to obtain a c...
Embodiment 3
[0029] (1) Maca dried fruit is soaked in water until there is no hard core, and treated with a colloid mill to obtain a slurry, preheat the slurry to 60°C, adjust the pH with 1mol / L HCL and 1mol / L NaOH to make it at 6, add 3000U / L kg of cellulase to break the cell wall, dissolve the active substance inside, enzymatically hydrolyze for 6h, then inactivate the enzyme at 100°C for 10min, centrifuge at 8000rn for 20min, and obtain the supernatant;
[0030] (2) the supernatant is filtered through a mixed cellulose coarse filter membrane with a pore size of 0.6um to obtain a crude filtrate;
[0031] (3) add distilled water of 2 times the volume of the crude filtrate in the crude filtrate, and filter with an ultrafiltration membrane with a molecular cut-off of 50KD to remove enzymes and undecomposed macromolecules to obtain an ultrafiltrate;
[0032] (4) The ultrafiltrate was evaporated in vacuum at 60° C., and concentrated to 3% of the original volume to obtain a concentrated soluti...
