preparation example Construction

[0025] According to the preparation method of Rhizoma Polygonatum decoction pieces of the present invention, the method comprises the following operations:

[0026] Steps for grading: Polygonatum root tubers are graded according to diameters of 1.5-2cm, 2.5-3.5cm, and 3.5-5cm, and rinsed separately to obtain Polygonatum; Rhizoma Polygonatum root is selected as Rhizoma Polygonatum. Polygonatum yunnanensis is a plant of the genus Polygonatum in the family Liliaceae. Distributed in Vietnam, Myanmar, and Yunnan, Guizhou, Sichuan and other places in mainland China, it grows in areas with an altitude of 700 meters to 3,600 meters, and mostly grows on damp grass slopes, shrubs, forests and rocks. Polygonatum tuber is harvested after the beginning of winter and before the beginning of spring. The best harvesting period is from the beginning of winter to the beginning of spring every year. Because the tubers of Polygonatum yunnanensis are planted in the top soil of 1-20cm, they are ha...

Embodiment 1

[0034] Example 1: The method for preparing Rhizoma Polygonatum decoction pieces in this example is as follows: firstly harvest Rhizoma Rhizoma Rhizoma Rhizoma Rhizoma Rhizoma Polygonatum from Lidong to before Lichun, and pour the seedlings before Lidong, and the best harvesting period is from Lidong to Lichun every year , Harvest from the edge of the border surface and dig into the soil horizontally with a hoe, try not to hurt the roots of Rhizoma Polygonatum. .

[0035] Grading steps: classify Polygonatum root tubers according to diameters of 1.5-2cm, 2.5-3.5cm, and 3.5-5cm, and rinse them separately. First soak for 40 minutes, and then rinse them with a high-pressure water gun while turning them until they are clean. The pressure of the high-pressure water gun is 2Mpa. Polygonatum root tuber is selected from Yunnan Polygonatum.

[0036] Cooking steps: Steam the rinsed sealwort with a diameter of 1.5-2cm for 2 hours, 1.5-2cm for 2.5 hours, and 3.5-5cm for 3 hours to cook sep...

Embodiment 2

[0041] Embodiment 2: the method that present embodiment prepares Rhizoma Polygonatum decoction pieces is:

[0042] Steps for grading: classify the tubers of Rhizoma Polygonatum according to the diameters of 1.5-2cm, 2.5-3.5cm, and 3.5-5cm, and rinse them separately. First soak for 20 minutes, and then rinse them with a high-pressure water gun with a pressure of 3Mpa until they are clean.

[0043] Cooking steps: Steam the rinsed Polygonatum cubes with a diameter of 1.5-2cm for 1.5 hours, 1.5-2cm for 3 hours, and 3.5-5cm for 2.5 hours;

[0044] Drying step: remove the skin and fibrous roots of the boiled Polygonatum, and dry it at 70°C until it is 30% dry (the water content of Polygonatum accounts for 70% of that before drying);

[0045] Re-cooking steps: steam the dried sealwort according to the diameter of 1.5-2cm for 30 minutes, 2.5-3.5cm for 25 minutes, and 3.5-5cm for 20 minutes;

[0046] Re-drying step: re-dry the re-cooked Rhizoma Polygonatum to below 40% dryness; below ...

Abstract

The invention relates to a rhizoma polygonati decoction piece and a preparation method thereof, belonging to the technical field of Chinese crude drug processing. The preparation method specifically comprises the steps of firstly grading rhizoma polygonati root tubers according to three diameter sizes of 1.5 to 2cm, 2.5 to 3.5cm and 3.5 to 5cm, respectively removing cortex and fibre, respectively stewing, respectively drying until the dryness is below two tenth, respectively steaming dried rhizoma polygonati for 1.5 to 2.5h, 2 to 3h and 2.5 to 3.5h according to different diameters, removing cortex and fibre again, and drying until the weight is below 80 percent of original fresh weight. The steps are repeated, day drying in the sun and night exposing are repeated for multiple times, and when the rhizoma polygonati is dried to have the weight below 20 percent of the original fresh weight, the rhizoma polygonati is sliced and dried in the sun to obtain ripe rhizoma polygonati pieces. The obtained rhizoma polygonati decoction piece is higher in beneficial component content and perfect in mouthfeel.

Description

technical field [0001] The invention relates to sealwort decoction pieces and a preparation method thereof, belonging to the technical field of traditional Chinese medicine processing. Background technique [0002] Polygonatum, also known as tiger ginger and chicken head ginseng. It is the dried rhizome of Rhizoma Polygonatum, Polygonatum Polygonatum or Polygonatum Polyflora of Liliaceae. Polygonatum is used as medicine with rhizomes. It has the functions of invigorating qi and nourishing yin, invigorating the spleen, moistening the lungs and benefiting the kidney. It is used to treat weak spleen and stomach, tiredness and fatigue, dry mouth and lack of food, dry cough due to lung deficiency, insufficient essence and blood, internal heat and thirst. After making vinegar, the astringent and astringent properties are enhanced, and the astringent essence has a stronger antidiarrheal effect. For spermatorrhea, diarrhea. There are four processing methods recorded in the mode...
