Problems solved by technology

In addition, the previous research on the extraction of active ingredients of Dendrobium candidum only focused on polysaccharides, dendrobine and other components, but the extraction of dietary fiber was not involved, which led to the waste of raw materials of Dendrobium candidum

Embodiment 1

[0057] This example is a preparation example of extracting dietary fiber from defatted dendrobium powder, omitting the material processing steps.

[0058] The first step: preparing the dietary fiber crude extract, which specifically includes the following steps:

[0059] Step 1.1: Flash extraction.

[0060] First, take 18 g of defatted Dendrobium powder made from 57.0 g of fresh Dendrobium officinale stems and leaves (water content 80%), add 50 times 85% ethanol, and adjust the pH to 10. Ethanol is added gradually, constantly stirring, so that the defatted dendrobium powder is evenly distributed in it, and avoids agglomeration. After mixing, adjust the pH to 10, and extract with a flash extractor for 2 minutes, divided into two times, 30 seconds each time, and adjust the flash extractor to 120V. Then centrifuge, the condition of centrifugation is 5000r / min, 15min. Precipitate A was obtained after centrifugation.

[0061] Step 1.2: Enzymatic digestion.

[0062] Take the prec...

Embodiment 2

[0083] This example is another preparation example of extracting dietary fiber from defatted dendrobium powder, which omits the material processing steps.

[0084] The first step: preparing the dietary fiber crude extract, which specifically includes the following steps:

[0085] Step 1.1: Flash extraction.

[0086] First, take 15 g of defatted Dendrobium powder made from 60.2 g of fresh stems and leaves of Dendrobium officinale, add 50 times of 85% ethanol, and adjust the pH to 10. Ethanol is added gradually, constantly stirring, so that the defatted dendrobium powder is evenly distributed in it, and avoids agglomeration. After mixing, adjust the pH to 10, and extract with a flash extractor for 1 minute, divided into two times, 60 seconds each time, and adjust the flash extractor to 120V. Then centrifuge, the condition of centrifugation is 5000r / min, 30min. Precipitate A was obtained after centrifugation.

[0087] Step 1.2: Enzymatic digestion.

[0088] Take the precipit...

Embodiment 3

[0109] This example is the preparation example of extracting dietary fiber from fresh Dendrobium officinale.

[0110] The first step: material pretreatment:

[0111] Weigh 69.1g of fresh Dendrobium officinale stems and leaves frozen at -20°C, cut into pieces, dry, and pulverize. Then use sherwood oil to reflux for 4 hours, filter it, and then use sherwood oil to wash the dendrobium powder, so as to obtain the defatted dendrobium powder, which is reserved for use;

[0112] The second step: prepare the dietary fiber crude extract, which specifically includes the following steps:

[0113] Step 2.1: Flash extraction.

[0114] First, take 20 g of defatted dendrobium powder, add 50 times of 85% ethanol, and adjust the pH to 10. Ethanol is added gradually, constantly stirring, so that the defatted dendrobium powder is evenly distributed in it, and avoids agglomeration. After mixing, adjust the pH to 10, and extract with a flash extractor for 2 minutes, divided into two times, 30 ...

Abstract

The invention provides a method for extracting dietary fibers from dendrobium officinale. The method is used for extracting dietary fibers components of parts of stems, leaves and the like of the dendrobium officinale by a flash extraction device. Compared with the prior art, the method is moderate in extraction conditions and short in extraction time; the extraction time is only 1-3 minutes; the dosage of a solvent is small and the extraction efficiency is high; the extraction efficiency is up to 4.16%-5.68%; the separated extraction of water-soluble dietary fibers and water-dissoluble dietary fibers of the dendrobium officinale is realized; the effective extraction efficiency and the comprehensive utilization rate of components of the dendrobium officinale are improved; the wastes of resources are avoided.

Description

technical field [0001] The invention belongs to the technical field of extraction and separation of active ingredients of Chinese herbal medicines, and in particular relates to a method for extracting dietary fiber from dendrobium officinale. Background technique [0002] Dendrobium officinale is the whole herb of the perennial epiphytic herb of Dendrobium orchidaceae. It is a precious Chinese herbal medicine, which has the functions of enhancing the body's immunity, anti-tumor, promoting the secretion of digestive juice, inhibiting platelet aggregation, lowering blood fat, lowering blood sugar, anti-oxidation, Anti-aging, antipyretic and analgesic and other pharmacological effects, its composition is diverse, mainly including dietary fiber, polysaccharides, amino acids, alkaloids, phenanthrene compounds, etc. [0003] Dietary fiber is very important for human metabolism. Dietary fiber has at least the following functions: increase gastrointestinal peristalsis to ensure nor...
