What are the extraction methods for the active ingredients of reishi mushroom?
The extraction methods for the active ingredients of reishi mushroom are determined by the properties of those active ingredients. The main active ingredients of reishi mushroom include reishi polysaccharides, ganoderic acids, adenosine, ergosterol, saponins, purines, pyrimidines, alkaloids, lactones, and so on. Most of these ingredients are soluble in hot water, but among them ganoderic acids, saponins, ergosterol and other components have low solubility in hot water while their solubility in ethanol is very high. From an economic perspective, ethanol extraction is costly and not very cost-effective. 1. Hot water extraction method: crush the reishi mushroom into pieces 0.5-1 cm in size
