Embodiment 1
[0029] (1) Remove the fresh walnut green skin in the early stage of maturity, wash it, chop it, and freeze-dry to form a pretreated walnut green skin with a length less than 1cm. Add 8ml of 3% mass fraction to 1g of the pretreated green skin The fermented enzyme solution was fermented at 40°C for 1 day at low temperature to obtain the fermented product of walnut green husk.
[0030] (2) Break the fermented product of walnut green husk into mud, and add it into ethanol water solvent with a volume ratio of 2:1 at a material-to-liquid ratio of 1g:30ml, after ultrasonic treatment for 30min, heat and stir at 60°C for 30min, and filter to obtain Primary filtrate and primary filter residue;
[0031] (3) With the ratio of solid to liquid as 1g:10ml, add the primary filter residue in methanol, ultrasonically treat it for 60min, heat and stir at 60°C for 30min, and filter to obtain a secondary filtrate with a mass fraction of 10%, with the ratio of solid to liquid as 10ml: 1g, add gela...
Embodiment 2
[0034] (1) Remove the fresh walnut green skin in the early stage of maturity, wash it, chop it, and freeze-dry to form a pretreated walnut green skin with a length of less than 1cm. Add 10ml of the mass fraction to 1g of the pretreated green skin to be 5%. The fermented enzyme solution was fermented at a low temperature of 50° C. for 2 days to obtain a fermented product of walnut green husk.
[0035] (2) Break the fermented product of walnut green husk into mud, and add it into ethanol water solvent with a volume ratio of 4:1 at a material-to-liquid ratio of 1g:50ml, after ultrasonic treatment for 30min, heat and stir at 70°C for 60min, and filter to obtain Primary filtrate and primary filter residue;
[0036] (3) With the material-liquid ratio as 1g:20ml, add the primary filter residue in methanol, ultrasonically treat it for 60min, heat and stir at 70°C for 60min, and filter to obtain a secondary filtrate with a mass fraction of 15%, with the material-liquid ratio as 20ml: ...
Embodiment 3
[0039] (1) Remove the fresh walnut green skin in the early stage of maturity, wash it, chop it, and freeze-dry to form a pretreated walnut green skin with a length of less than 1cm. Add 9ml of 4% mass fraction to 1g of the pretreated green skin The fermented enzyme solution is fermented at 45° C. for 1-2 days at a low temperature to obtain a fermented product of walnut green husk.
[0040] (2) Break the fermented product of walnut green husk into mud, add 1g40ml of solid-liquid ratio to the ethanol water solvent with a volume ratio of 2-4:1, after ultrasonic treatment for 30min, heat and stir at 65°C for 40min, and filter to obtain Primary filtrate and primary filter residue;
[0041] (3) With the ratio of material to liquid being 1g:15ml, the primary filter residue was added in methanol, ultrasonically treated for 60min, heated and stirred at 70°C for 40min, and filtered to obtain a secondary filtrate with a mass fraction of 12%, with a ratio of material to liquid of 15ml: 1g,...
