1, hot water extraction method will be broken into 0.5 to 1 cm large pieces of Ganoderma lucidum into the stainless steel pot, add 14 times the weight of Ganoderma lucidum deionized water (calcium ions, magnesium ions, also known as soft water, so as not to affect the pot life And guarantee the extraction quality). Steam is blown into the bottom of the kettle and the water is boiled for 2 hours. The decoction (head decoction) is removed. Residue remains in the pot, plus 12 times the amount of deionized water, fried 2 hours, take two decoction. Combine the two fluids, input into the reservoir, and stand still for 10 hours. Take the supernatant. First general concentration, and then concentrated under reduced pressure, when the specific gravity of 1: 1.36 or so (hot test), that is Ganoderma stream extract, can be used to process into Ganoderma slices, Ganoderma capsules, Ganoderma agents.
2. The alcohol extraction method is the same as above, and 95% of the dry weight of Ganoderma lucidum is used to eat 95% of the edible alcohol, 78% of the reflux is for 1 hour, and the ethanol is taken out; the residue is added 8 times the weight of 75% of the edible ethanol, and the same is refluxed. Extract; add 50% ethanol for the third time and take three extracts. The three liquids are combined and left to stand in a liquid storage tank for 10 hours. The supernatant liquid is taken and the ethanol is recovered. The concentrate can be made into a tincture, or it can be dried or spray-dried to make capsules and other preparations.
Ganoderma lucidum active ingredient extraction method
Ganoderma lucidum active ingredient extraction method is determined by the nature of the active ingredients of Ganoderma lucidum. Ganoderma lucidum active ingredients mainly include Ganoderma lucidum polysaccharide, ganoderic acid, adenosine, ergosterol, saponin, purine, pyrimidine, alkaloid, lactone and so on. Most of these components are soluble in hot water. Among them, ganoderic acid, saponins, and ergosterol have low solubility in hot water and high solubility in ethanol. From an economic point of view, the cost of ethanol extraction is high and it is not cost-effective.
