Embodiment 1
[0041] 1) Collect the defective lily scales after processing, and place them in an ultrasonic cleaner for 20 minutes, with an ultrasonic power of 400W. After washing, remove and dry.
[0042] 2) The lily scales of step 1) are placed in a blast oven and dried until the water content is less than 10%, and the drying temperature is 50°C.
[0043] 3) The lily scales in step 2) are placed in a pulverizer (200 mesh screen) and pulverized into lily powder.
[0044] 4) Weigh 100 g of lily powder in step 3), soak it in 15 times the amount of distilled water for 2 hours, seal it, and place it in a high-pressure extraction device. Extract at 108°C, 0.035MPa for 30min, centrifuge after cooling, separate the precipitate, and concentrate the supernatant to 1 / 4 of the original volume under reduced pressure.
[0045]5) Add ethanol to the above concentrate to obtain a mixed solution, adjust the amount of ethanol added to 70-80% of the total volume of the mixed solution, let it stand for 24 h...
Embodiment 2
[0048] 1) Collect the defective lily scales after processing, and place them in an ultrasonic cleaner for 10 minutes, with an ultrasonic power of 1000W. After washing, remove and dry.
[0049] 2) The lily scales of step 1) are placed in a blast oven and dried until the water content is less than 10%, and the drying temperature is 45°C.
[0050] 3) Put the lily scales in step 2) into a pulverizer (80 mesh sieve) and pulverize into lily powder.
[0051] 4) Weigh 500 g of lily powder in step 3), soak it in 20 times the amount of distilled water for 12 hours, seal it, and place it in a high-pressure extraction device. Extract at 110°C, 0.05MPa for 25min, centrifuge after cooling, separate the precipitate, and concentrate the supernatant to 1 / 6 of the original volume under reduced pressure.
[0052] 5) Add ethanol to the above concentrate to obtain a mixed solution, adjust the amount of ethanol added to 70-80% of the total volume of the mixed solution, let it stand for 12 hours, ...
Embodiment 3
[0055] 1) Collect the defective scales of lily after processing, and place them in an ultrasonic cleaner for cleaning for 15 minutes with an ultrasonic power of 200W. After washing, remove and dry.
[0056] 2) The lily scales of step 1) are placed in a blast oven and dried until the water content is less than 10%, and the drying temperature is 45°C.
[0057] 3) The lily scales in step 2) are placed in a pulverizer (100 mesh screen) and pulverized into lily powder.
[0058] 4) Weigh 100 g of lily powder in step 3), soak it in 80 times the amount of distilled water for 1 hour, seal it, and place it in a high-pressure extraction device. Extract at 120°C, 0.1MPa for 30min, centrifuge after cooling, separate the precipitate, and concentrate the supernatant under reduced pressure.
[0059] 5) Add ethanol to the above concentrate to obtain a mixed solution, adjust the amount of ethanol added to 70-80% of the total volume of the mixed solution, let it stand for 48 hours, centrifuge,...
