Abstract

The invention discloses a method for extracting dendrobium officinate kimura et migo polysaccharide by using an ultrasonic method. The method comprises the following steps: on the basis of a traditional water extraction method, heating and extracting a sizing agent of the dendrobium officinate kimura et migo through an ultrasonic water bath, determining proper technical parameters and extracting pure dendrobium officinate kimura et migo polysaccharide. Compared with the traditional water extraction method, the method disclosed by the invention has the advantage of low water consumption, environment friendliness and high yield of the dendrobium officinate kimura et migo polysaccharide.

Description

technical field [0001] The invention relates to a method for extracting components of dendrobium candidum, in particular to a method for extracting polysaccharides from dendrobium candidum by using an acid-base method, and belongs to the field of deep processing of dendrobium candidum. Background technique [0002] Dendrobium officinale is a large genus of Orchidaceae and a traditional rare medicinal material in my country. Modern pharmacological studies have proved that Dendrobium officinale has anti-tumor, enhancing immunity, anti-platelet aggregation, and treating cataracts. The content of polysaccharides in Dendrobium officinale is relatively high , Dendrobium polysaccharides have the effects of improving immunity and anti-tumor. [0003] The extraction of Dendrobium polysaccharides mostly adopts traditional water extraction and alcohol precipitation methods, such as (patent: a purification method of Dendrobium officinale polysaccharides-CN 104892783 A) and its process st...
