Abstract

The invention discloses a shitake extract sustained-release pellet which is prepared from shitake extractives and pharmaceutical accessories and are externally coated by sustained-release films; each sustained-release film comprises a polymer material, a pore-foaming agent and an anti-bonding agent; the shitake extractives are 20-40% of the weight percentage content of a pellet preparation, and the sustained-release film is 2-10% of the weight percentage content of the pellet preparation; the pharmaceutical accessories consist of an excipient and a binder, wherein the excipient is 50-75% of the weight percentage content of the pellet preparation, while the binder is 1-5% of the weight percentage content of the pellet preparation. The sustained-release pellet prepared by using the preparation method of the shitake extractive sustained-release pellet can be used for adjusting the immunity, and the area of the sustained-release pellet on the surface of an absorbing organ is increased, so that the bioavailability is increased and the local stimulation is reduced or avoided.

Description

technical field [0001] The invention relates to a sustained-release pellet of mushroom extract. [0002] The invention also relates to a preparation method of the mushroom extract sustained-release pellets. Background technique [0003] Shiitake mushrooms can increase energy, treat colds and remove intestinal parasites. The key ingredient of shiitake mushrooms is Xianggu polysaccharide. The products of shiitake mushroom extract are well recognized by consumers. These products are basically ordinary tablets and capsules. However, the above-mentioned dosage forms have a long disintegration time and disintegrate at a certain point in the body, which has a certain effect on the gastric mucosa. Irritation, low bioavailability point and other shortcomings, based on the above problems, we quickly introduced the pellet technology in the field of medicine to the field of food. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of ...
