Method for extracting peony essential oil from peonies

Abstract

The invention relates to a method for extracting peony essential oil from peonies. The method comprises the following steps that step 1, the peonies are picked, forced air drying is conducted on the peonies, and the dried peonies are taken out and ground; step 2, a cellulase water solution and a pectinase water solution are mixed, acetum is added, and therefore a phosphoesterases complex solution is obtained; step 3, the ground peonies are placed in a triangular flask, the phosphoesterases complex solution is added, standing is conducted, ultrasonic treatment is conducted, and standing is conducted; step 4, the obtained solution in the step 3 is added to a petroleum ether ethanol solution, backflow is conducted, digestion is conducted at the indoor temperature, and the obtained solution is transferred into a rotary evaporator for vacuum concentration. According to the method, enzyme treatment is firstly conducted on the peonies so that local changes of loosening, expansion, crashing and the like are generated in the cell walls of the peonies and the mesenchyme structures of the cell walls; then, ultrasonic treatment is conducted on the peonies for a short time, and therefore the extraction rate of the essential oil from the cells of the peonies is greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of plant biology, and in particular relates to a method for extracting peony essential oil from peony flowers. Background technique

[0002] Peony essential oil is extracted from the flowers, leaves, roots and fruits of peony. It is rich in amino acids and trace elements needed by the human body. It can effectively scavenge oxygen free radicals, inhibit skin pigmentation, remove wrinkles, reduce skin spots and female stretch marks. Improve blood microcirculation, remove skin toxins, improve dry skin and shrink pores, making skin smooth and elastic. Peony essential oil is a natural plant hormone that balances hormone secretion in women, relieves women's dysmenorrhea, and nourishes the uterus. Antioxidant: The unique peony polyphenols in peony essential oil are strong antioxidants, which can also prolong the time of other antioxidants in the body and delay skin aging. At the same time, it inhibits pigmentat...

[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...
