Method for extracting oleaginous substances from ganoderma lucidum (linghzi) spores

The present invention relates to a method for extracting the oleaginous substances from sporoderm-broken Ganoderma/linghzi spores using SCF-CO2. The method contains the steps of breaking the Ganoderma/linghzi spores by a mechanical means to obtain the sporoderm-broken spores; and extracting the oleaginous substances from the sporoderm-broken spores using a supercritical fluid - carbon dioxide (SCF-CO2) extraction method. Before breaking the spores by a mechanical means, there may be steps of inducing germination of Ganoderma/linghzi spores by incubating the spores in a nutritional solution and activating the Ganoderma/linghzi spores by placing the germination-induced spores in a well ventilated culture box kept at constant temperature and humidity to obtain the sporoderm-broken spores. As for SCF-CO2, the preferred supercritical conditions include 5 M to 60 M Pa of pressure; 32 DEG C to 85 DEG C of temperature; and 5 kg/h to 80 kg/h of flow capacity rate. The total extraction time in SCF-CO2 is between 0.5 hour to 6 hour. The method produces approximately 37% by weight of oleaginous substances from the sporoderm-broken Ganoderma/linghzi spores. These oleaginous substances are transparent and contain the special fragrance of Ganoderma/linghzi spores. There is no trace of deposit, solvent residue, or oxidization in the oleaginous substances.
