Embodiment 1
[0058] Embodiment 1: a kind of extracting method of yarrow extract, comprises the following steps:
[0059] S1, crush 1 kg of yarrow to obtain 1 kg of yarrow powder with a particle size of less than 80 μm, add 2.1 g of cellulase, extract with 5 L of deionized water in a water bath at a temperature of 30° C. for 0.5 h, and cool to room temperature to obtain extract;
[0060] S2, microfilter the extract, during the microfiltration, use ceramic filter membranes of 74 μm, 5 μm, and 0.22 μm in sequence to filter under the condition of a surface pressure of 0.5 MPa, collect 4 L of the filtrate, and obtain the crude extract of Yarrow;
[0061] S3, on the ultrafiltration system, use the cellulose filter membrane that molecular weight cut off is 1K, the condition that surface pressure is 0.5MPa carries out ultrafiltration to the crude extract of yarrow, collects 3.5L of filtrate;
[0062] S4, the ultrafiltration filtrate is subjected to nanofiltration concentration. During nanofiltratio...
