Problems solved by technology

[0003] Dendrobium mainly contains alkaloids and polysaccharides, alkaloids are not water-soluble and difficult to extract
Traditional processing is mostly based on personal experience, and the quality of the processed product depends on the operator's personal subjective judgment, which may easily cause the quality of the processed product to be unstable.

Embodiment 1

[0029] Dendrobium processing method, comprises the following steps:

[0030] 1. Take the stem of Dendrobium officinale, remove the residual root, wash it, cut it into cylindrical or flat cylindrical segments with a length of 5 mm, and dry at 80 degrees Celsius for 2 hours;

[0031] 2. Wine moistening: put the cut Dendrobium in a container, add 50% ethanol solution and mix well, the weight ratio of ethanol solution to Dendrobium is 15:100, seal and moisten for 1 hour, and the ethanol solution slowly penetrates into the Dendrobium tissue , so that the cut Dendrobium section maintains a uniform humidity to achieve the same internal and external humidity.

[0032] 3. Steaming: Put the dendrobium moistened with wine into a porcelain jar, heat it with steam for 6 hours, take it out, and dry it in the air.

[0033] The content of the extracted active ingredients is high, the content of dendrobine is 0.256%, the content of polysaccharide is 11.05%, and there is no residue of impuriti...

Embodiment 2

[0035] Dendrobium processing method, comprises the following steps:

[0036] 1. Take stems of Dendrobium officinale, remove residual roots, wash them, cut into cylindrical or oblate cylindrical segments with a length of 10 mm, and dry at 80 degrees Celsius for 3 hours;

[0037] 2. Wine moistening: put the cleaned or cut Dendrobium in a container, add 45% ethanol solution and mix well, the weight ratio of ethanol solution to Dendrobium is 20:100, seal and moisten for 1.5h, and the ethanol solution slowly penetrates To the inside of the dendrobium tissue, the cut section of the dendrobium can be kept at a uniform humidity to achieve the same internal and external humidity.

[0038] 3. Steaming: Put the dendrobium moistened with wine into a stainless steel steamer, heat it with steam for 8 hours, take it out, and dry it in the air.

[0039] The content of the extracted active ingredients is high, the content of dendrobine can reach 0.278%, the content of polysaccharide can reach...

Embodiment 3

[0041] Dendrobium processing method, comprises the following steps:

[0042] 1. Take the stems of Dendrobium officinale, remove the residual roots, wash them, cut them into cylindrical or oblate cylindrical sections with a length of 6 mm, and dry them at 80 degrees Celsius for 2.5 hours;

[0043] 2. Wine moistening: put the cleaned or cut Dendrobium in a container, add 48% ethanol solution and mix well, the weight ratio of ethanol solution to Dendrobium is 17:100, airtight and stuffy for 1.2h, and the ethanol solution slowly penetrates To the inside of the dendrobium tissue, the cut section of the dendrobium can be kept at a uniform humidity to achieve the same internal and external humidity.

[0044] 3. Steaming: Put the dendrobium moistened with wine into a stainless steel steamer, heat it with steam for 6.78 hours, take it out, and dry it in the air.

[0045] The content of the extracted active ingredients is high, the content of dendrobine can reach 0.303%, the content of...

Abstract

The invention provides a dendrobe processing method and a technical screening method of dendrobe. The dendrobe processing method is characterized by comprising a wine moistening step and a steaming step. The effective components extracted are high in content, the content of dendrobine can reach 0.303%, and the content of polysaccharides can reach 12.3%. The technical screening method is high in precision and accuracy, and interaction among factors can be inspected.

Description

technical field [0001] The invention relates to a processing method of medicinal materials, in particular to a processing method of Dendrobium dendrobii and a screening method for processing technology. technical background [0002] Dendrobium was first recorded in "Shen Nong's Materia Medica", listed as a top grade, and has the functions of "benefiting the stomach and promoting body fluid, nourishing yin and clearing away heat". "Pharmacopoeia of the People's Republic of China" 2010 Edition Part One contains the dry dendrobium processing method as "removing residual roots, washing, cutting into sections, and drying". The processing methods of dendrobium in "Sichuan Provincial Standards for Processing Chinese Herbal Pieces" and "Chongqing Municipal Standards and Standards for Processing Chinese Herbal Pieces" are the same as those in Pharmacopoeia. [0003] Dendrobium mainly contains alkaloids and polysaccharides, and alkaloids are not soluble in water and are difficult to ...
