Embodiment 1
[0022] A method for extracting peony essential oil from peony flowers, comprising the following steps:
[0023] Step 1. Picking mature and disease-free peony flowers, placing the peony flowers in an oven with a temperature of 30°C and blowing them to dry, then taking out the peony flowers and crushing them to 40 meshes for later use;
[0024] Step 2. Mix the cellulase aqueous solution with a mass concentration of 0.2 mg / mL and the pectinase aqueous solution with a mass concentration of 0.1 mg / mL in equal volumes, and add an acetic acid solution with a mass percentage concentration of 2% to the mixed solution until mixed When the pH value of the solution reaches 5.0, stir the mixed solution evenly and let it stand for 12 minutes to obtain a compound enzyme solution;
[0025] Step 3, put the peony flower obtained in step 1 into the triangular flask, add the compound enzyme liquid prepared in step 2 in the conical flask, the ratio of compound enzyme liquid and peony flower additi...
