Embodiment 1
[0025] A preparation method of Liuwei Dihuang oral liquid treated with stomach and trypsin, the steps are as follows:
[0026] (1) After pulverizing the Liuwei raw material medicine in Liuwei Dihuang Wan raw materials, the raw material powder is obtained, and then 200 grams of water and refined honey are added for every 100 grams of raw material powder, and the raw material slurry is obtained by mixing evenly;
[0027] (2) Add hydrochloric acid to the raw material slurry prepared in step (1) to adjust the pH value to 1.5, add 20 activity units of pepsin per 100 grams of Liuwei Dihuang Wan raw material, treat at 36°C for 3 hours, adjust with sodium carbonate The pH value is 8, and the pepsin-treated slurry is obtained;
[0028] (3) Add 50 activity units of trypsin per 100 ml to the pepsin-treated slurry prepared in step (2), treat at a temperature of 37° C. for 2 hours, and adjust the pH value to 5.5 with hydrochloric acid to obtain stomach, Liuwei Dihuang oral liquid treated ...
Embodiment 2
[0032] A preparation method of Liuwei Dihuang oral liquid treated with stomach and trypsin, the steps are as follows:
[0033] (1) After pulverizing the Liuwei raw material drug in the Liuwei Dihuang Wan raw material, the raw material powder is obtained, and then 600 grams of water and refined honey are added for every 100 grams of the raw material powder, and the raw material slurry is obtained by mixing evenly;
[0034] (2) Add acid to the raw material slurry prepared in step (1) to adjust the pH value to 2.2, add 60 activity units of pepsin per 100 grams of Liuwei Dihuang Wan raw material, and treat it for 2 hours at a temperature of 38 ° C, and adjust it with sodium carbonate. The pH value is 7.8, and the pepsin-treated slurry is obtained;
[0035] (3) Add 20 activity units of trypsin per 100 ml to the pepsin-treated slurry prepared in step (2), treat at a temperature of 37° C. for 3 hours, and adjust the pH value to 6 with hydrochloric acid to obtain stomach, Liuwei Dihu...

Abstract
The invention relates to a preparation method of pepsin and trypsin treated Liuwei Dihuang oral liquid. The preparation method comprises the following steps: (1) crushing Liuwei Dihuang pill raw materials to prepare raw material powder, adding water, and mixing uniformly to prepare raw material serous fluid; (2) adding acid into the raw material serous fluid to adjust the pH value, and adding pepsin for treatment, and adjusting the pH value by using alkali, thereby preparing pepsin treated serous fluid; and (3) adding trypsin into the pepsin treated serous fluid for treatment, and adjusting the pH value to prepare the pepsin and trypsin treated Liuwei Dihuang oral liquid. The pepsin and trypsin treated Liuwei Dihuang oral liquid is prepared by the preparation method provided by the invention by decomposing the traditional Liuwei Dihuang pill raw materials by virtue of pepsin and trypsin, is relatively small in side effect, and is palatable in sweet and sour tastes; and by virtue of practical application, after being taken for a long time, the pepsin and trypsin treated Liuwei Dihuang oral liquid not only can achieve a treatment effect of Liuwei Dihuang pills but also can greatly reduce the side effects causing stomach cold and digestion obstruction.
Description
technical field [0001] The invention relates to a preparation method of Liuwei Dihuang Oral Liquid treated with stomach and trypsin, in particular to a method for processing classic Liuwei Dihuang Pills prescription by using biotechnology, which belongs to the technical field of biomedicine. Background technique [0002] Liuwei Dihuang Wan originated from Jinkui Shenqi Wan in "Synopsis of the Golden Chamber" by Zhang Zhongjing, a great medical scientist in the Eastern Han Dynasty. It is also called "Shenqi Wan" and "Bawei Dihuang Wan". Qian Yi, the national imperial physician, subtracted cinnamon and aconite from the original prescription to form Liuwei Dihuang, which is composed of Rehmannia glutinosa, Cornus officinalis, Chinese yam (three tonics), Poria cocos, Alisma, and Moutan cortex (three tonics). Pills; three tonics and three diarrhea, tonic but not dry. Liuwei Dihuang Wan has been formulated for more than 1,000 years since the Song Dynasty. It has been enduring for...
