Abstract

The invention relates to a willow needle mushroom glycocalyx, as well as a preparation method and application thereof, and belongs to the field of natural medicine development. The preparation method comprises the following steps: inoculating willow needle mushroom seeds into a culture medium, wherein the culture conditions such as temperature, rotational speed and time are 22 to 26 DEG C, 120 to 160 r/min, and 5 to 6 days respectively; inoculating 10 to 20 percent inoculum concentration of the willow needle mushroom seeds into a fermentation culture medium, wherein the fermentation conditions such as temperature, rotational speed and time are 22 to 26 DEG C, 120 to 160 r/min, and 5 to 6 days respectively; carrying out centrifugation to collect a supernatant at the rotational speed of 4000 r/min to 6000 r/min; carrying out rotary evaporation and concentration till the volume is 1/10 to 1/8 of the original volume; adding anhydrous ethanol of which the volume is 3 to 5 times of the concentrated liquid at the temperature of 4 DEG C for 12 to 16 hours' precipitation; carrying out 10 to 20 minutes' centrifugation, wherein the rotational speed is 3000 to 5000 r/min; collecting the precipitate; drying the precipitate at 45 to 50 DEG C. The willow needle mushroom glycocalyx fills up the blank of resource development and utilization of willow needle mushroom in the market. Moreover, an important foundation for deep development of polysaccharide immunological accelerator medicine and health foods with immunomodulatory effects is provided, and the economic value and the marketable value are high.

Description

technical field [0001] The invention belongs to the field of natural medicine development, and in particular relates to a fermented liquid extract of Flammulina velutipes and its preparation method and application. Background technique [0002] Edible and medicinal fungi are a very important class of natural biological resources, and have become an important research object in the discovery of new drugs and the development of functional foods. Studies have shown that edible and medicinal fungi contain polysaccharides, proteins, flavonoids and other active substances, which have various pharmacological effects such as improving immunity, anti-tumor, and anti-oxidation. At present, Lentinan, Ganoderma lucidum polysaccharide, and Polyporus polysaccharide have been approved by the health department and have become clinical anti-tumor immunotherapy drugs. Although a large number of edible and medicinal fungus polysaccharides have been developed and utilized, due to the rich fung...
