Process for extracting dendrobium polysaccharide and dendrobine from dendrobium officinale

Abstract

The invention provides a process for extracting dendrobium polysaccharide and dendrobine from dendrobium officinale. The raw material used in the process comprises dendrobium officinale, cellulase (a biochemical reagent), glucose, phenol, acetone, petroleum ether and absolute ethyl alcohol. According to the process provided by the invention, the polysaccharide and dendrobine in the dendrobium officinale are extracted by using cellulase-catalyzed extraction in a combination manner; the dendrobine is obtained when the dendrobium polysaccharide is obtained; high efficiency for single extraction of the polysaccharide by an enzymic method is kept; the effects of effectively breaking cell walls are improved; dissolution of polysaccharide and the like are promoted; the process and condition are mild; the extraction rate is improved to a certain extent; and the economic benefits are relatively high.

Description

technical field

[0001] The invention relates to the field of dendrobium processing, in particular to an extraction process of dendrobium polysaccharides and dendrobine in dendrobium candidum. Background technique

[0002] Modern pharmacological studies have proved that Dendrobium plants have the effects of anti-tumor, enhancing body immunity, anti-platelet aggregation, and treating cataracts. Among them, Dendrobium polysaccharides have the effects of improving immunity and anti-tumor; can improve hematopoiesis and blood coagulation; , liver, kidney, and gastrointestinal lesions are effective; it also has a significant effect on scalds, viruses, and bacterial infections; Dendrobium alkaloids can be used to prevent and treat arthritis, protect the digestive tract mucosa from acute or chronic damage, and are especially used to prevent acute and chronic digestion. Canker sores. Dendrobium polysaccharides are extracted by traditional water extraction and alcohol precipitation me...
