Embodiment 1
[0050] A method for extracting crude polysaccharides from peony leaf rachis of the present invention comprises the following steps:
[0051] Step 1): Raw material pretreatment, taking peony leaf rachis with uniform thickness, removing the petiole on the peony leaf rachis, washing and drying, crushing with a pulverizer until completely passing through a 50-100 mesh sieve, and obtaining leaf rachis powder; the raw rachis is preferably Seven-year-old, vigorous growth, no pests and diseases, about 35cm long, uniform leaf rachis, remove the petiole on the leaf rachis, clean the peony leaf rachis, put them in a drying oven, dry at 60°C until constant weight, and use a cyclone Grind it and sieve it; the raw material is sufficiently crushed, which is beneficial to the dissolution of the active ingredients in the leaf axis;
[0052] Step 2): extracting and separating the rachis powder obtained in step 1), and collecting the separated supernatant to obtain the crude extract of peony rac...
