Extracting method for ganoderma lucidum spore oil

Abstract

The invention discloses an extraction method for ganoderma lucidum spore oil. The extraction method comprises the following steps: (1) cleansing ganoderma lucidum spores; (2) breaking the walls of the ganoderma lucidum spores to obtain ganoderma lucidum spore powder; (3) preparing the wall-broken ganoderma lucidum spore powder into particles through a granulator by adopting a dry pressing method; (4) putting the particles into a supercritical CO2 extraction kettle for extraction; (5) isolating coarse ganoderma lucidum spore oil; (6) rectifying and separating to obtain the ganoderma lucidum spore oil. According to the invention, absolute ethyl alcohol-acetone is adopted as an entrainer, so that the polarity range of the extraction agents is expanded, and the extraction efficiency is effectively improved; when the walls of ganoderma lucidum spore powder are broken, natural antioxidant vitamin E is added, so that the effective constituents of the ganoderma lucidum spore powder can be effectively prevented from being oxidized and rancidified; the superfine nanometer technology is adopted, so that the local overheating phenomenon can be avoided in the smashing process and the effective active constituents in the ganoderma lucidum spore powder can be greatly retained; the coarse ganoderma lucidum spore oil is rectified and separated in nitrogen, so that the effective constituents in the ganoderma lucidum spore oil can be effectively protected from being oxidized and rancidified.

Description

technical field [0001] The present invention relates to the extracting method of ganoderma lucidum spore oil, particularly relate to a kind of using supercritical CO 2 A method for extracting Ganoderma lucidum spore oil by extraction and separation technology. Background technique [0002] Ganoderma lucidum, also known as Ruicao and Ganoderma lucidum, is a traditional Chinese medicine that strengthens the body, strengthens the body, and nourishes and strengthens. It has been listed as the top grade of Chinese medicine in medical books of all dynasties. Ganoderma lucidum is a fungus of Polyporaceae, known as "immortal grass". It has the effects of invigorating qi and calming the nerves, relieving cough and relieving asthma. Biology is listed as the first choice. Ganoderma lucidum spores are the seeds released by the growth and maturity of Ganoderma lucidum. They are the germ cells of Ganoderma lucidum. They have all the genetically active substances of Ganoderma lucidum. S...

AI Technical Summary

Problems solved by technology

[0005] In summary, the existing supercritical CO 2 There are following weak points in extraction technology: 1) supercritical CO 2 During the extraction process, CO 2 The polarity of Ganoderma lucidum is weak. It can only extract non-polar components and very small polar components. The polarity range is wide, and higher extraction conditions are required to be extracted. Although there is a scheme to assist extraction by using ethanol aqueous solution as an entrainer in the prior art, the solubility of water to triterpenoids is extremely low. Solubility of similar compounds is also general, and after using ethanol aqueous solution as entrainer in the extraction process, in gained Ganoderma lucidum spore oil contains trace water and is difficult to remove completely, thereby has affected the quality of oil; 2) when using Ganoderma lucidum spore powder as raw material extraction When it was broken, no protective measures were taken for the broken Ganoderma lucidum spore powder, which made the oils and triterpenoids on the surface of the broken Ganoderma lucidum spore powder very easy to be oxidized and rancid, thereby reducing a part of the Ganoderma lucidum. Oil yield of spore powder and quality of obtained Ganoderma lucidum spore oil
