Abstract

The invention belongs to the technical field of plant extraction, in particular to a method for extracting perilla aldehyde, comprising the following steps: (1) spraying treatment agent A on the surface of perilla leaves, refrigerating immediately after spraying, taking out after refrigerating, and waiting for the perilla leaves to recover to room temperature, and then refrigerated; (2) spray treatment agent B on the surface of refrigerated perilla leaves, add ethyl acetate to microwave extraction after crushing, filter, remove the pigment in the filtrate, and obtain extract 1; (3) Add a solid oxidant to the extract 1 to react, filter, and recover the ethyl acetate in the filtrate under reduced pressure to obtain the extract 2; (4) use a reverse osmosis membrane to concentrate the extract 2, and freeze-dry the concentrate to powder . The method for extracting perillaldehyde provided by the present invention can improve the dissolution rate of perillaldehyde in perilla leaves, prevent the oxidation reaction of perillaldehyde in the extraction process, and at the same time, part of the perillyl alcohol extracted from perilla leaves The conversion into perillaldehyde improves 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 perilla aldehyde. Background technique [0002] Perilla, also known as Guiren, Chisu, etc., is an annual herb of the Lamiaceae family of Perilla 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. Perilla is warm, pungent, and enters the lung meridian. It contains perillaldehyde, eugenol, perillone, perillol, limonene, polyphenols and other biologically active substances. The role of chest and relieving depression and miscarriage is generally used to treat colds, cold, mental fatigue, stagnation of spleen and stomach, nausea and vomiting. [0003] Perilla aldehyde is an essential active ingredient in natural perilla leaves. It has fragrance, cherry and high-quality ...
