Fresh-cut processing technology for reed rhizome medicinal material

Abstract

The invention discloses a fresh-cut processing technology for a reed rhizome medicinal material. The technology comprises the following steps: after the reed rhizome is harvested, when the surface of the reed rhizome is adhered to clay and wet, washing the reed rhizome with water, clearing up the rhizome, tedding for 12-48 hours, performing fresh cut to form round slices or elliptical slices when the material is fresh, airing until the medicinal material is dried, packaging the material with a polyethylene plastic bag, vacuumizing and adding a drying agent. The method is to wash and process the medicinal material when the material is fresh, so that the loss of water-soluble effective constituents can be avoided, the pollution of the medicinal material caused by microorganism and worm eggs in soil can be reduced, the production working procedures of the prepared herbal medicine for decoction can be simplified, the manufacturing cost can be lowered, the medicinal material quality can be ensured, and clinical effects are improved; the method can be popularized and applied to achieve obvious social meaning and economic benefits.

Description

technical field [0001] The invention belongs to the field of processing of traditional Chinese medicinal materials, and in particular relates to a production-place processing technology of traditional Chinese medicinal reed rhizome decoction pieces. Background technique [0002] Reed root is the rhizome of grass Phragmites reed. This product is sweet in nature and cold in flavor; it belongs to the lung meridian and stomach meridian; it has the functions of clearing away heat and promoting body fluid, eliminating restlessness, relieving vomiting, and diuresis. Clinically, it is mainly used for polydipsia due to febrile disease, vomiting due to stomach heat, cough due to lung heat, pus vomiting due to lung abscess, hot stranguria and astringent pain. [0003] At present, after the fresh reed rhizome is harvested, it is usually sorted out, dried in the sun, packed for storage and transported. After these dried reed rhizomes are transported to the traditional Chinese medicine ...

AI Technical Summary

Problems solved by technology

The existing process is time-consuming and laborious, and the process is repeated, which increases the production cost of decoction pieces

In this process, it will not only lead to a large loss of active ingredients such as asparagine and caffeic acid, but also if the moistening process is carried out in high temperature seasons, it is easy to cause mildew of the medicinal materials, resulting in a decline in the quality of the medicinal materials and a reduction in clinical efficacy.
