A kind of extraction method of Ganoderma lucidum spore oil

Abstract

This case discloses a method for extracting ganoderma spore oil, which includes the following steps: 1) cleaning ganoderma spores; 2) breaking the wall of ganoderma spores to obtain ganoderma spore powder; 3) using a granulator to dry the ganoderma spore powder 4) put the Ganoderma lucidum spore powder particles into supercritical CO 2 extraction in the extraction kettle; 5) separating the crude ganoderma spore oil; 6) rectifying and separating to obtain the ganoderma spore oil. In this case, absolute ethanol-acetone was used as the entraining agent, which broadened the polar range of the extractant and effectively improved the extraction efficiency; by adding natural antioxidant vitamin E when breaking the wall of Ganoderma lucidum spore powder, it effectively avoided its active ingredients Oxidation and rancidity; ultra-micro and nano-wall breaking technology is used to avoid local overheating during the pulverization process, and the effective and active ingredients in Ganoderma lucidum spore powder are retained to the greatest extent; crude Ganoderma lucidum spore oil is rectified and separated in nitrogen to effectively protect Ganoderma lucidum The active ingredients in the spore oil are not oxidized and rancid.

Description

Technical field [0001] The invention relates to an extraction method of Ganoderma lucidum spore oil, in particular to a method that uses supercritical CO 2 A method for extracting ganoderma lucidum spore oil by extraction separation technology. Background technique [0002] Ganoderma lucidum, also known as Seocao and Ganoderma lucidum, is a traditional Chinese medicine for strengthening the body and strengthening the body, nourishing and strong. It is listed as the top-grade Chinese medicine in medical books of the past dynasties. Ganoderma lucidum is a fungus of the Polyporaceae family, known as the "fairy grass". It has the effects of replenishing qi, soothing the nerves, relieving cough and relieving asthma. It is used for dizziness, insomnia, palpitations, shortness of breath, asthenia, fatigue, cough, and asthma. It is listed as the first choice among creatures. Ganoderma lucidum spores are the seeds released during the growth and maturation period of Ganoderma lucidum. The...

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
