Embodiment 1

[0042] Soaking with mixed detergent

[0043] Prepare mixed cleaning agent: Take 0.5kg sodium citrate and 0.5kg sodium bicarbonate, add 19L of pure water, stir and dissolve evenly, and get mixed cleaning agent, set aside.

[0044] Polygonatum multiflora freshly excavated from the ground is washed with water to remove the sediment on the surface of Polygonatum; remove fibrous roots and rinse with tap water. Put 500g of washed Rhizoma Polygonatum in a mixed cleaning agent at room temperature (23°C±2°C) for soaking treatment, rinse with clean water after soaking, and dry the surface of Rhizoma Polygonatum in a hot air oven at 60°C Moisture, that is to complete the preliminary processing of sealwort.

Embodiment 2

[0052] Investigation on the Mixing Ratio of Mixed Cleaning Agent

[0053] Prepare mixed cleaning agent: Weigh sodium citrate and bicarbonate according to the weight ratio of 1:1, 1:4, 1:7, 1:10, 1:15, 1:20, 1:30, 1:40 Add 1kg of sodium in total, then add it into 19L of water, stir and dissolve evenly to obtain a mixed cleaning agent, which is set aside.

[0054] Wash the fresh Polygonatum multiflora excavated from the ground with clear water to remove the sediment on the surface of Polygonatum; remove the fibrous roots and rinse with tap water. Put 500g of washed Polygonatum multiflora into the above-mentioned mixed cleaning agent for 30 minutes at room temperature (23°C±2°C), rinse with clean water after soaking, and dry in a hot air oven at 60°C Polygonatum surface moisture, that is, complete the preliminary processing of Polygonatum.

[0055] The prepared Polygonatum product was tested for heavy metal residues in the same manner as in Example 1, and the results are show...

Embodiment 3

[0060] Soaking temperature investigation

[0061] Weigh 0.2 kg of sodium citrate and 0.8 kg of sodium bicarbonate, then add them into 19 L of water, stir and dissolve evenly to obtain a mixed cleaning agent, which is set aside.

[0062] Wash the freshly excavated Rhizoma Polygonatum with clear water to remove the sediment on the surface of Rhizoma Polygonatum; remove fibrous roots and rinse with tap water. Wash 500g Polygonatum Polygonatum and set aside. Put the mixed cleaning agent in a water bath and heat it to a constant temperature of 25-60°C. After the temperature of the cleaning agent is stable, add Rhizoma Polygonatum, soak for 30 minutes, rinse with clean water after soaking, put it in a hot air oven at 60°C to dry the surface moisture of Rhizoma Rhizoma Polygonatum, and complete the preliminary processing of Rhizoma Rhizoma Polygonatum.

Abstract

The invention relates to the technical field of traditional Chinese herbal medicine processing, in particular to a rhizoma polygonati green processing technology. The technology comprises the following steps: step 1, washing fresh rhizoma polygonati with clear water to remove silt on the surface of rhizoma polygonati; step 2, putting the rhizoma polygonati obtained in the step 1 into a mixed cleaning agent to be soaked for 10 min to 120 min; step 3, washing the rhizoma polygonati obtained in the step 2 with clear water for at least one time. The mixed cleaning agent is an aqueous solution mainly prepared from sodium bicarbonate and sodium citrate. The fresh rhizoma polygonati is soaked with the mixed cleaning agent, the content of residual heavy metal in the fresh rhizoma polygonati is effectively reduced, so that a phenomenon that harmful substances on the surface of the rhizoma polygonati enter the rhizoma polygonati in the steaming process and thus the quality of the rhizoma polygonati is affected, and indirect harm is caused to the human body is avoided.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese herbal medicine processing, in particular to a green processing technology of sealwort. In the present invention, the sealwort is processed greenly in the place of origin, and the quality of the sealwort can be rapidly improved with a small processing workload, so that the sealwort can output a rough product of the sealwort with better quality. Background technique [0002] Polygonatum is a plant of the genus Polygonatum in the family Liliaceae. The 2015 edition of "Chinese Pharmacopoeia" records the species as Polygonatum sibircum Red., Polygonatum Cyrtonema Hua or Polygonatum Kingianum Col1.et Hemsl. The dried rhizome of Polygonatum Kingianum Col1.et Hemsl. Different, it is commonly known as "chicken head Polygonatum", "ginger-shaped Polygonatum" and "rhubarb". [0003] The traditional processing method of Polygonatum is as follows: take fresh Polygonatum, remove fibrous roots, rins...
