Ganoderma lucidum sterol and preparation method and use thereof
The project relates to a pharmaceutical preparation containing organic active ingredients, in particular to the preparation of a sterol extract of Ganoderma lucidum, which is extracted from Ganoderma lucidum and is mainly composed of white flake crystals. its name is 24-methyl-cholest-5p22-dien-3 β-ol, which has the effect of anti-cerebral ischemia caused by various diseases in preparation. In particular, the drugs which have the effect of anti-hypoxia of cortical neurons have outstanding curative effect.

New cultivation techniques of Ganoderma lucidum in semi-underground arch shed
The method of cultivating Ganoderma lucidum by covering soil with semi-underground arch shed has many advantages: first, the construction cost of semi-basement shed is lower than that of ground shed, which can save 40% of the construction expenditure; second, it is convenient for water management, as long as it keeps sufficient moisture in the overlying soil layer; third, Ganoderma lucidum grows at one end, nutrition is concentrated, and the Ganoderma lucidum is robust and of good quality. Fourth, the semi-basement arch shed is warm in winter and cool in summer. When the outdoor ground temperature is about 40 ℃ in summer, the inside of the shed is no more than 36 ℃, and in winter it is 3 ℃-4 ℃ higher than the ground. The roof skylight can meet the requirements of light and ventilation. Its technical introduction is as follows

Extraction method of effective components of Ganoderma lucidum
The extraction method of effective components of Ganoderma lucidum is determined by the properties of effective components of Ganoderma lucidum. The main active ingredients of Ganoderma lucidum are Ganoderma lucidum polysaccharides, ganoderic acid, adenosine, ergosterol, saponins, purines, pyrimidines, alkaloids, lactones and so on. Most of these ingredients can be dissolved in hot water, in which ganoderic acid, saponins, ergosterol and other components have low solubility in hot water, but high solubility in ethanol. From an economic point of view, ethanol extraction is expensive and not cost-effective. 1. Ganoderma lucidum was broken into 0.5cm by hot water extraction.
