Abstract

The invention discloses a method for extracting polysaccharides of ginseng palm, which comprises: taking ginseng palm and coarse powder, passing through a 20-mesh sieve to obtain ginseng palm powder; adding 4-5 times the weight of sodium bicarbonate and sodium sulfite to the ginseng palm powder The mixed solution is soaked at normal temperature for 1-1.5h, centrifugally filtered, so that the water content of the filter cake is 45-50%, and the first filter cake is obtained; the first filter cake is broken up, placed in a steam explosion tank, and Carry out superheated steam spray explosion treatment under the state of motion, obtain steam explosion; Add the water of 20-25 weight times of the weight meter of described palm ginseng powder in described steam explosion, extract 40-50min under normal temperature, centrifuge filtering to make the water content of the filter cake less than 20%, taking the filtrate to obtain a water extract; concentrating the water extract under reduced pressure, alcohol precipitation and drying to obtain the polysaccharide of Panax japonicus. The invention has the advantages of no degreasing treatment, short extraction time, high yield, good product activity preservation, suitable for industrial promotion and the like.

Description

technical field [0001] The invention relates to the field of polysaccharide extraction. More specifically, the present invention relates to a method for extracting ginseng palm polysaccharide. Background technique [0002] Ginseng palm (Latin scientific name: Gymnadenia conopsea (L.) R.Br.), is a commonly used Mongolian and Tibetan medicine. It has the effect of replenishing qi and enhancing physical fitness, and it is mainly used as a nourishing food in Tibet and other places. Polysaccharide is one of the active ingredients of palm ginseng, which has the functions of anti-oxidation and regulating immunity. The existing extraction process of palm ginseng polysaccharides is mainly to grind and degrease palm ginseng, then extract with hot water, ultrasonic wave or microwave, and process the extract by centrifugation, concentration under reduced pressure, alcohol precipitation and drying. The hot water extraction method has the problems of long extraction time period and low...
