Abstract

Belonging to the technical field of plant extraction, the invention particularly relates to an extraction method of perillaldehyde. The method includes the processes of: (1) spraying a treatment agentA to the surfaces of perilla leaves, then performing refrigeration immediately, then taking the product out, and after the perilla leaves restore to room temperature, conducting refrigeration again;(2) spraying a treatment agent B to the surfaces of the refrigerated perilla leaves, performing crushing, then adding ethyl acetate for microwave extraction, conducting filtering, and removing pigmentfrom the filtrate to obtain an extracted liquid 1; (3) adding a solid oxidant into the extracted liquid 1 for reaction, performing filtering, and then conducting pressure reduced recovery of ethyl acetate in the filtrate to obtain an extracted liquid 2; and (4) concentrating the extracted liquid 2 by a reverse osmosis membrane, and freeze-drying the concentrated liquid into powder. The extractionmethod of perillaldehyde provided by the invention can improve the dissolution rate of perillaldehyde in perilla leaves, prevent oxidation reaction of perillaldehyde in the extraction process, at thesame time can convert part of the perillyl alcohol extracted from perilla leaves into perillaldehyde, and increases the extraction rate of perillaldehyde in perilla leaves.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, in particular to a method for extracting perillaldehyde. Background technique [0002] Perilla, also known as Guiren, Chisu, etc., is an annual herb of the Lamiaceae family native to the central and southern regions of China in the Himalayas. Perilla has been cultivated in my country for more than 2,000 years. It is a traditional multi-purpose economic crop with a variety of medicinal and edible effects. It is also one of the first batch of medicinal and edible crops promulgated by the Ministry of Health. Perilla is warm, pungent, and enters the lung meridian. It contains perillaldehyde, eugenol, perillone, perillyl alcohol, limonene, polyphenols and other biologically active substances. The function of chest and relieving stagnation and antenatal is generally used to treat colds and colds, mental fatigue, stagnation of spleen and stomach, nausea and vomiting. [0003] Perillaldehyde i...
