Embodiment 1

[0022] The preparation method of dendrobium paste, comprises the steps:

[0023] Pre-processing steps: Cut Dendrobium into slices with a thickness of about 2mm

[0024] Step (1) Extraction: add dendrobium and water to the extraction device, first rapidly raise the temperature of the extraction device to 70°C, then use a 1°C / min gradient to raise the temperature, heat it to 90°C and keep it for 10 minutes, and finally use a 1°C / min gradient to cool down, The total time of a heat preservation extraction process is 50min, and the extract is collected;

[0025] Ethanol reflux extraction step, add ethanol with a volume fraction of 70% to the device to reflux for 20 minutes, and collect the extract, wherein the ratio of the weight of Dendrobium to the volume of ethanol is 1:2;

[0026] Adding water to repeatedly extract the water extraction operation for 2 times, between every two water extraction operations, an ethanol reflux extraction operation is required, wherein the volume of...

Abstract

The invention relates to dendrobe extract, and discloses a method for preparing dendrobe cream. The method comprises the following steps of 1 extraction, wherein dendrobe and water are added to an extracting device, extraction is carried out for 30-60 min at the temperature kept at 70 DEG C to 90 DEG C, then an extracting solution is collected, water is added to repeat the extraction operation two to three times, and the ratio of the weight of dendrobe to the volume of water is 1:2-10; 2 concentration, drying and forming, wherein the extraction solution is combined, pressure reducing concentration and drying are carried out to obtain the dendrobe cream, and the water content of the dendrobe cream ranges from 5% to 15%. According to the method, effective ingredients in dendrobe are extracted and preserved well, and the eating convenience degree of dendrobe is greatly improved.

Description

technical field [0001] The invention relates to a dendrobium extract, in particular to a preparation method of a dendrobium paste. Background technique [0002] Dendrobium is a well-known yin-tonifying traditional Chinese medicine, which has the functions of nourishing yin and clearing heat, promoting body fluid and benefiting stomach, moistening lung and relieving cough, benefiting kidney and improving eyesight. Modern studies have shown that it has the functions of anti-tumor, enhancing the body's immunity, anti-platelet aggregation, improving vision, dilating blood vessels, and anti-oxidation. [0003] The current way of taking medicine of Dendrobium is mainly decoction, which can reflect the characteristics of TCM syndrome differentiation, addition and subtraction according to the syndrome, flexible medication, fast absorption, strong effect and long-term use, but with the development of the times and the progress of science and technology The traditional way of taking ...
