Abstract

The invention relates to a supercritical CO2 variable-temperature variable-pressure extraction method of lucid ganoderma spore oil. The method comprises the steps that: 1, lucid ganoderma spores are subjected to wall breaking, such that lucid ganoderma spore powder is obtained; 2, the wall-broken lucid ganoderma spore powder is prepared into particles with a dry-pressing method, such that particles with a size of 20-60 meshes are obtained; 3, the spore powder particles are placed into a supercritical CO2 extraction kettle with a three-stage separation structure; an ethanol water solution with a mass percentage of 20-95% is adopted as carrying agent, wherein 20-300ml of the 20-95% ethanol water solution is placed with each kilogram of material in the extraction kettle; and supercritical extraction is carried out, wherein an extraction pressure is 20-50MPa. The extraction process is a multi-stage extraction process, wherein extraction is carried out for 1-4h under a temperature of 30-40 DEG C, and extraction is carried out for 1-4h under a temperature of 40-60 DEG C. With the method, various effective components in lucid ganoderma spores can be more effectively extracted, such that the possibility for the lucid ganoderma spore active components to be broken is effectively reduced. The quality of the extraction product is improved, and the requirement of people is satisfied.

Description

technical field [0001] The present invention relates to the deep processing technology of Ganoderma lucidum spore powder, especially refers to the use of supercritical CO 2 A method for extracting Ganoderma lucidum spore oil by variable temperature and variable pressure technology. Background technique [0002] Ganoderma lucidum has been called "fairy grass" since ancient times. It has a long history of 5,000 years in China. It has always been regarded as a "panacea" by ancient emperors and a symbol of "good luck". ". The Ming Dynasty "Compendium of Materia Medica" records that Ganoderma lucidum "has a bitter taste, non-toxic, nourishes the middle and nourishes Qi, increases wisdom, has a good color, long-term food makes light of body and does not grow old, and prolongs life and immortality." Now, Ganoderma lucidum has been recorded in Chinese Pharmacopoeia, and it is an important raw material of Chinese medicinal materials and health food approved by the state. Ganoderma...
