Abstract

The invention relates to a method for extracting antrodia camphorata oil by employing a CO2 supercritical extraction process. The method comprises: cleaning antrodia camphorata, quickly freezing at -35 DEG C, drying in vacuum to have a water content less than 2%, crushing by a refrigeration pulverizer, sieving, and performing supercritical CO2 extraction; controlling an extraction tank to have the temperature of 35 DEG C and the pressure of 25 MPa, and controlling the CO2 flow to be 35 L/h, and adding food-grade 96% ethanol as an entrainer; controlling a separation tank to have the temperature of 30 DEG C and the pressure of 10 MPa; and controlling a rectification column to have the temperature of 25 DEG C and the pressure of 12 MPa, so as to obtain antrodia camphorata oil. The antrodia camphorata oil obtained by extraction has the advantages of high effective compositions, no residual organic solvents and the like, the extraction technology is easy to operate, the extraction yield is high, and the product can be used as a raw material for producing traditional Chinese medicines and health products.

Description

technical field [0001] The invention relates to an extraction method, in particular to an extraction method of active ingredients of Antrodia camphorata, belonging to the technical field of traditional Chinese medicine extraction. Background technique [0002] Antrodia cinnamomea, also known as camphor mushroom, is scientifically named Antrodia camphorata. It belongs to the order Aphylloides, Polyporaceae, and perennial fungi. It is a new fungus discovered by the biochemical community in 1990. Wild camphor wood has been listed as one of the national treasures by the government in recent years. The growth area of ​​Antrodia camphorata is in the mountains and forests at an altitude of 450-2000 meters in the mountains of Taiwan. Cinnamomum camphora wood wet surface, because of its high medicinal and edible value, and its output is scarce, the extraction research and application research of its active ingredients are beginning in China. [0003] Antrodia camphorata is rich in β...
