Abstract

The invention discloses a method for one-time separation and extraction of dendrobe polysaccharide, dendrobine and erianin from dendrobium candidum. The method for extraction of dendrobe polysaccharide, dendrobine and erianin from dendrobium candidum comprises the steps of crushing of dendrobe, enzymatic hydrolysis, ultrasonic extraction, microfiltration, ultrafiltration and nano-membrane concentration, solid-liquid separation, vacuum cryogenic distillation, solvent extraction, solvent recovery, recrystallization, vacuum low-temperature drying and purification in the carbon dioxide supercritical fluid, thereby obtaining the dendrobe polysaccharide, dendrobine and erianin. The prepared product has good color, good solubility and high active ingredients.

Description

technical field [0001] The invention discloses a method for separating and extracting dendrobium polysaccharide, dendrobine and erianin from dendrobium candidum by using carbon dioxide supercritical fluid. Background technique [0002] Scientific research has proved that the medicinal ingredients of Dendrobium officinale are mainly polysaccharides, alkaloids and erianin, etc. Dendrobium polysaccharides can improve human immunity; enhance memory; nourish the five internal organs; anti-aging; inhibit tumors; Hypoxia; It has a significant effect on radiotherapy and chemotherapy, night life, excessive smoking and alcohol, and Dendrobium Erianin can significantly inhibit the proliferation of tumor cells; Dendrobine has the effect of eliminating human fatigue. Therefore, the functional components of Dendrobium officinale have been widely used in the fields of medicine, health care and food, and have a great potential market. Comprehensive development and utilization of functional...
