Embodiment 1
[0031] A kind of method for extracting rutizin, comprising the following processing steps:
[0032] (1) Drying: Vacuum freeze-drying the fresh leaves (with a phloridin content of 7.89%) of the fresh leaves of Shikeia polycarpa to a moisture content of ≤15% to obtain dried leaves;
[0033] (2) Pulverization: Put the dried leaves in a traditional Chinese medicine pulverizer, pulverize them to a particle size of 100 mesh, and get Duosui Shike powder;
[0034] (3) Ultrasonic extraction: Take 1 kg of Duosuishike powder and add it to an ultrasonic container, then add ethanol (85% ethanol concentration) and 10 L of dimethyl carbonate mixed solvent with a volume ratio of 3:1, and ultrasonicate at a power of 250W Extract for 30 minutes, place the liquid obtained by ultrasonic extraction in a high-speed centrifuge at 10,000 rpm for 2 minutes to obtain supernatant and precipitate;
[0035] (4) Repeat ultrasonic extraction: put the precipitate obtained in step (3) into an ultrasonic cont...

[0042] A kind of method for extracting rutizin, comprising the following processing steps:
[0043] (1) Drying: Vacuum freeze-drying the fresh leaves (with a phloridin content of 7.89%) of the fresh leaves of Shikeia polycarpa to a moisture content of ≤15% to obtain dried leaves;
[0044] (2) Pulverization: put the dried leaves in a traditional Chinese medicine pulverizer, pulverize them to a particle size of 150 mesh, and obtain Duosui Shike powder;
[0045](3) Ultrasonic extraction: Take 1 kg of Duosuishike powder and add it to an ultrasonic container, then add ethanol (ethanol concentration: 90%) and 12L of dimethyl carbonate mixed solvent with a volume ratio of 4:1, and ultrasonically at a power of 300W Extract for 25 minutes, place the liquid obtained by ultrasonic extraction in a high-speed centrifuge at 10,000 rpm for 3 minutes to obtain supernatant and sediment;
[0046] (4) Repeat ultrasonic extraction: Add the precipitate obtained in step (3) to 10L of ethanol and d...
Embodiment 3
[0053] A kind of method for extracting rutizin, comprising the following processing steps:
[0054] (1) Drying: Vacuum freeze-drying the fresh leaves (with a phloridin content of 7.89%) of the fresh leaves of Shikeia polycarpa to a moisture content of ≤15% to obtain dried leaves;
[0055] (2) Pulverization: put the dried leaves in a traditional Chinese medicine pulverizer, pulverize them to a particle size of 200 mesh, and obtain Duosui Shike powder;
[0056] (3) Ultrasonic extraction: Take 1kg of Duosuishike powder and add it to an ultrasonic container, then add ethanol (ethanol concentration: 95%) and 15L of dimethyl carbonate mixed solvent with a volume ratio of 5:1, and ultrasonicate at a power of 350W Extract for 20 minutes, place the liquid obtained by ultrasonic extraction in a high-speed centrifuge at 10,000 rpm for 5 minutes to obtain supernatant and precipitate;
[0057] (4) Repeat ultrasonic extraction: Add the precipitate obtained in step (3) into an ultrasonic co...
