Embodiment 1

[0044] Embodiment 1: Chinese toon leaf prickly ash essential oil:

[0045] Take the fruit of Zanthoxylum bungeanum, wash and dry to a water content of 25%, and carry out extrusion and puffing treatment with a twin-screw extruder under the conditions of a feeding speed of 4000g / h, a screw speed of 300r / min, and an extrusion temperature of 100°C. Put it in a traditional Chinese medicine grinder and grind it until it passes through a 100-mesh sieve, and then dry it to a water content of 10%. Take 100g of Zanthoxylum bungeanum powder and add it to 300mL of deionized water, stir evenly and seal the film. At a frequency of 50KHz and a density of 0.65W / cm 2 1. Ultrasonic extraction at a temperature of 55° C. for 60 minutes, then adding 7 mg of NaCl to the mixture, and distilling for 6 hours to obtain colorless and transparent essential oil of Zanthoxylum bungeanum.

Embodiment 2

[0046] Embodiment 2: Chinese toon leaf prickly ash essential oil:

[0047] Take the fruit of Zanthoxylum bungeanum, wash and dry to a water content of 20%, and carry out extrusion and puffing treatment with a twin-screw extruder under the conditions of a feeding speed of 2000g / h, a screw speed of 450r / min, and an extrusion temperature of 105°C. Put it in a traditional Chinese medicine grinder and grind it until it passes through a 100-mesh sieve, and then dry it to a water content of 5%. Take 100g of Zanthoxylum bungeanum powder and add it to 350mL of deionized water, stir evenly and seal the film. At a frequency of 45KHz and a density of 0.6W / cm 2 1. Ultrasonic extraction for 45 minutes at a temperature of 58° C., then adding 7 mg of NaCl to the mixture, and distilling for 8 hours to obtain colorless and transparent essential oil of Zanthoxylum bungeanum.

Embodiment 3

[0048] Embodiment 3: Chinese toon leaf prickly ash essential oil:

[0049] Take the fruit of Zanthoxylum bungeanum, wash and dry to a water content of 22%, and carry out extrusion and puffing treatment with a twin-screw extruder under the conditions of a feeding speed of 3500g / h, a screw speed of 420r / min, and an extrusion temperature of 110°C. Put it in a traditional Chinese medicine grinder and grind it until it passes through a 100-mesh sieve, and then dry it to a water content of 8%. Take 100g of Zanthoxylum bungeanum leaf powder and add it to 300mL of deionized water, stir evenly and seal the film. At a frequency of 80KHz and a density of 0.8W / cm 2 1. Ultrasonic extraction for 30 minutes at a temperature of 60° C., then adding 7 mg of NaCl to the mixture, and distilling for 8 hours to obtain colorless and transparent essential oil of Zanthoxylum bungeanum.

Abstract

The invention relates to the technical field of plant essential oil preparation, in particular to a preparation method and application of Zanthoxylum ailanthoides essential oil, which comprises the following steps: extruding and puffing leaves or fruits of Zanthoxylum ailanthoides, conducting pulverizing, enabled the pulverized material to pass thruogh a 60-100-mesh sieve, conducting drying untilthe water content is 5-12%, adding Zanthoxylum ailanthoides powder into a large amount of deionized water, conducting even stirring, conducting sealing with a film, conducting ultrasonic extraction for at least 60 min, adding NaCl into a mixed solution, and conducting distilling for at least 5 hours to obtain colorless and transparent Zanthoxylum ailanthoides essential oil. The preparation processof the Zanthoxylum ailanthoides essential oil is simple, an organic extraction agent does not need to be added, the recovery process of the organic extraction agent is avoided, the yield of the Zanthoxylum ailanthoides essential oil is high, and it is verified that the Zanthoxylum ailanthoides essential oil has the excellent bacteriostatic effect and the effect of reducing the serum uric acid level of a hyperuricemia model mouse.
