Process for extracting effective components from culture medium after ganoderma lucidum picking

Abstract

The invention discloses a process for extracting effective components from a culture medium after ganoderma lucidum picking, which comprises the following steps: (1) selecting the culture medium without infectious microbe pollution after ganoderma lucidum picking, spraying water on the surface, culturing for 2-4 days, and collecting bacterial colonies on the surface; (2) carrying out washing treatment on the obtained culture medium, and standing the washing solution to remove the bottom precipitate, so as to obtain a suspension containing ganoderma lucidum hyphae; (3) separating and purifying the ganoderma lucidum hyphae in the suspension to obtain purified ganoderma lucidum hyphae; and (4) combining the bacterial colonies and the ganoderma lucidum hyphae, then performing water extraction for 3-5 times, combining extracting solutions, performing standing to remove precipitate at the bottom layer, and taking supernate, thereby the extracting solution of the effective components in the culture medium after the ganoderma lucidum pickling is obtained. According to the method, the ganoderma lucidum hyphae in the culture medium after the ganoderma lucidum is picked are firstly collected and then are separated and purified, finally, the effective components are extracted, the process is simple, the design is reasonable, the extracted effective components are all from the ganoderma lucidum, and impurity components in the culture medium are not introduced.

Description

technical field [0001] The invention belongs to the technical field of extracting active ingredients of ganoderma, and more specifically relates to a process for extracting active ingredients from culture medium after picking ganoderma. Background technique [0002] Ganoderma lucidum, umbrella-shaped in shape, with a kidney-shaped, semicircular or nearly round cap, is the fruiting body of the polyporaceae fungus Ganoderma lucidum, and is one of the famous edible and medicinal fungi in my country. Modern medicine has proved that Ganoderma lucidum contains a variety of physiological regulatory factors that have obvious effects on the human body, and the most important active ingredients are Ganoderma lucidum polysaccharide and Ganoderma acid. Ganoderma lucidum polysaccharides mainly refer to monosaccharide polymers with physiological activity. Ganoderma lucidum polysaccharides have the functions of anti-tumor, improving the immune activity of the body, scavenging free radicals...

Problems solved by technology

And because the fruiting body of Ganoderma lucidum is derived from the growth and development of Ganoderma lucidum hyphae, there are often Ganoderma lucidum mycelia left on the culture medium after Ganoderma lucidum is cultivated, but at present, the culture medium after picking Ganoderma lucidum is mostly discarded and not used. The active ingredients of Ganoderma lucidum have not been effectively extracted, resulting in waste

However, although some manufacturers process and extract Ganoderma lucidum together with the culture medium when picking Ganoderma lucidum, impurities in the culture medium are introduced into the Ganoderma lucidum extract, especially the polysaccharides in the raw material of the culture medium will be used as Ganoderma lucidum polysaccharides, resulting in effective Ganoderma lucidum. The purity of the ingredients is not enough, which affects the efficacy of the medicine
