Embodiment Construction

[0013] In order to make the content of the present invention easier to understand, the technical solutions of the present invention will be further described below in conjunction with specific embodiments, but the present invention is not limited thereto.

[0014] A method for extracting perillaldehyde, comprising the following steps:

[0015] 1) Dry the perilla leaves in an oven for several hours, then grind them with a German Retsch ZM200 ultracentrifugal grinder (Retsch ZM200) until they pass through a 40μm sieve, then weigh 15g of the obtained powder, put it into a beaker, and add 50ml mixed with absolute ethanol;

[0016] 2) Put the mixture obtained in step 1) on a magnetic stirrer and stir for 10 minutes, drain it into a flask with a glass rod, wash the beaker with 250ml of absolute ethanol several times, and put the washing liquid into the flask to Make the powder all wash into the flask;

[0017] 3) Plug the mouth of the flask tightly with a rubber stopper, then put ...

Abstract

The invention discloses a method for extracting perillaldehyde. The method comprises the steps of drying and pulverizing perilla leaves, performing condensation reflux extraction with anhydrous ethanol as a solvent, then concentrating and freeze-drying to obtain the perillaldehyde. The yield of the perillaldehyde is 12.927%, which is higher than that in the conventional extraction method. The method can promote the development of perillaldehyde products.

Description

technical field [0001] The invention specifically relates to a method for extracting perillaldehyde. Background technique [0002] Perillaldehyde is an important component in natural plant green sage leaves and perilla leaves, which can be added to food, tobacco, and cosmetics as spices. At present, the production method of perillaldehyde is mainly based on chemical synthesis, which causes more or less some chemical reagents and even toxic substances to be introduced into the final product. In order to solve the problems existing in the synthesis of perillaldehyde, the invention provides a method for extracting perillaldehyde. Contents of the invention [0003] The object of the present invention is to provide a method for extracting perillaldehyde. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A method for extracting perillaldehyde, comprising the following steps: [0006] 1) Grind perilla leaves after d...
