Problems solved by technology

The medicinal effect of Dendrobium officinale is mainly because it contains a variety of active ingredients, such as alkaloids, polysaccharides, amino acids, etc., but the efficacy of various active ingredients is not the same
However, the clinical application of Dendrobium candidum mainly takes effect by making decoction from medicinal materials of Dendrobium candidum, and the efficacy of each active ingredient has not been targetedly applied. Therefore, some researchers have extracted and separated different active in

Abstract

The invention relates to a method for preparing cold-soluble Dendrobium officinale extract. The method comprises the following steps: (1) crushing and soaking of Dendrobium officinale; (2) enzymatic hydrolysis; (3) filtration; (4) purification; (5) concentration; (6) cooling and filtration; and (7) drying and powder discharging for obtaining the cold-soluble Dendrobium officinale extract. The preparation method allows the water-soluble Dendrobium officinale extract to be obtained, and the Dendrobium officinale extract is Dendrobium officinale polysaccharides. The Dendrobium officinale extractcan be quickly dissolved in cold water, the minimum dissolution temperature can reach 8 DEG C, and 6 g of the Dendrobium officinale extract can be dissolved in 100 g of 8 DEG C water, so the Dendrobium officinale extract prepared in the invention is a cold-soluble substance. The Dendrobium officinale extract has good water solubility, so the Dendrobium officinale extract can be used in the deep researches of the pharmacology and efficacy of the Dendrobium officinale polysaccharides.

Description

technical field [0001] The invention relates to a preparation method of a cold-soluble dendrobium officinale extract. Background technique [0002] Dendrobium officinale is a perennial epiphytic herb of the family Dendrobium genus. It is the top grade of Dendrobium medicinal materials. It is sweet in taste, heavy in quality, flexible and sticky. Treatment of febrile disease, body fluid injury, deficiency of stomach yin, flaccidity of muscles and bones, etc. Modern pharmacological studies have shown that Dendrobium officinale can enhance both non-specific and specific immunity, and has significant pharmacological effects in anti-tumor, anti-oxidation, lowering blood sugar and treating cataracts. The medicinal effect of Dendrobium officinale is mainly because it contains a variety of active ingredients, such as alkaloids, polysaccharides, amino acids, etc., but the efficacy of various active ingredients is not the same. However, the clinical application of Dendrobium candidu...
