Embodiment 1
[0024] A method for extracting flavonoids in pine leaves, which is prepared by the following steps: (1) Wash and break pine leaves, add water, Inonotus obliquus suspension, Aspergillus oryzae suspension, butyric acid bacteria Bacterial suspension, yeast suspension, stirred and fermented at 35°C for 10h;
[0025] (2) Then add cellulase at 35°C, stir at 70r / min for 10min, cool to room temperature, then at 25kHz, sonicate for 20min, concentrate by rotary evaporator 2 to half of the original volume, add petroleum Ether, heated at 40°C, stirred at 70r / min for 2min, after cooling, added ethanol solution, stirred at 5°C for 3min, then stood still for 2h, centrifuged and took the supernatant to obtain the flavonoid extract.
[0026] In the described step (1), pine needles: water: Inonotus obliquus bacterial suspension: Aspergillus oryzae bacterial suspension: Butyricum bacterial suspension: the mass volume ratio of yeast bacterial suspension is 200g: 600ml: 5ml: 1ml : 1ml: 0.3ml; pin...
Embodiment 2
[0031] A method for extracting flavonoids in pine leaves, which is prepared by the following steps: (1) Wash and break pine leaves, add water, Inonotus obliquus suspension, Aspergillus oryzae suspension, butyric acid bacteria Bacterial suspension, yeast suspension, stirred and fermented at 38°C for 11h;
[0032] (2) Then add cellulase at 40°C, stir at 75r / min for 15min, cool to room temperature, then at 30kHz, sonicate for 25min, concentrate by rotary evaporator 2, concentrate to half of the original volume, add petroleum Ether, heated at 45°C, stirred at 75r / min for 3min, after cooling, added ethanol solution, stirred at 5.5°C for 4min, then stood still for 2.5h, centrifuged and took the supernatant to obtain the flavonoid extract.
[0033] In the described step (1), pine needles: water: Inonotus obliquus bacterial suspension: Aspergillus oryzae bacterial suspension: Butyricum bacterial suspension: the mass volume ratio of yeast bacterial suspension is 300g: 702ml: 8ml: 2ml ...
Embodiment 3
[0035] A method for extracting flavonoids in pine leaves, which is prepared by the following steps: (1) Wash and break pine leaves, add water, Inonotus obliquus suspension, Aspergillus oryzae suspension, butyric acid bacteria Bacterial suspension, yeast suspension, stirred and fermented at 40°C for 12h;
[0036] (2) Then add cellulase at 45°C, stir at 80r / min for 20min, cool to room temperature, then at 40kHz, sonicate for 30min, concentrate by rotary evaporator 2, concentrate to half of the original volume, add petroleum Ether, heated at 50°C and stirred at 80r / min for 5min, after cooling, added ethanol solution, stirred at 6°C for 5min, then stood still for 3h, centrifuged and took the supernatant to obtain the flavonoid extract.
[0037] In the described step (1), pine needles: water: Inonotus obliquus bacterial suspension: Aspergillus oryzae bacterial suspension: Butyricum bacterial suspension: the mass volume ratio of yeast bacterial suspension is 500g: 800ml: 10ml: 3ml ...
