Method for improving quality of radix scutellariae with sodium hyposulfite

Abstract

The invention discloses a method for improving the quality of radix scutellariae with sodium hyposulfite and relates to the technical field of radix scutellariae. The method comprises the steps of radix scutellariae fresh root extracting-washing-drying in shade for 1-2 days under the temperature of 20-25 DEG C-active oxygen carrier spraying-standing for 3-10 days under the temperature of 20-25 DEG C-drying. An active oxygen carrier is the sodium hyposulfite. The concentration of the sodium hyposulfite is 0.4 mumol / L-40 mmol / L. The processing time cycle is 3-15 days. Temperature is 10-35 DEG C. According to the method, traditional Chinese medicinal materials are planted in the zone most suitable for plants to grow in or in a main producing zone, various measures can be taken to improve yield, according to the essence of radix scutellariae quality forming, after medicine collecting, secondary metabolism of fresh medicine materials is subjected to human intervention, so that medicine material quality is greatly improved, and accordingly high quality and high yield are achieved. The secondary metabolism level of radix scutellariae is improved to the maximum degree, and the quality of all produced medicine materials reaches or exceeds the quality of famous-region drugs.

Description

Technical field: [0001] The invention relates to a method for improving the quality of Scutellaria baicalensis by using sodium dithionite, and belongs to the technical field of Scutellaria baicalensis. Background technique: [0002] The quality of Chinese medicinal materials is closely related to the environment; unsuitable environments such as high temperature, low temperature, strong light, drought, and nutrient levels affect the normal growth and development of organisms. Animals can move and can actively seek a suitable environment to survive, while plants cannot move and can only rely on changes in physiological metabolism to adapt to new unfavorable environments by producing secondary metabolites, which are usually what people need Medicinal ingredients. The distribution area of ​​plants is generally relatively wide, and there are great differences in climate and other environmental conditions in different regions, so the quality of medicinal materials in different re...

AI Technical Summary

Problems solved by technology

[0009] Secondly, under cultivation conditions, the growth environment of plants is greatly improved by measures such as irrigation and fertilization. Under such conditions, the production of secondary metabolites (usually the medicinal components of Scutellaria baicalensis) is unfavorable, and cultivation in authentic areas is not suitable. It will ensure that the quality of medicinal materials will be greatly improved

[0010] Third, due to factors such as terrain, fertilization, and annual rainfall, the quality of medicinal materials in authentic regions is uneven, and it is difficult to ensure the improvement and stability of the overall quality of medicinal materials

Measures such as irrigation, which are generally highly respected under cultivation conditions, still cannot improve the quality of medicinal materials

[0015] Second, many natural conditions that affect the quality of medicinal materials are difficult to control artificially, so that the quality of many medicinal materials produced in authentic areas is not high-quality

Even under natural conditions, the level of plant secondary metabolism is determined by the degree of unsuitability of the external environment, which is a process of quantitative change, and is not the highest level of secondary metabolism produced by Scutellaria baicalensis. The best level, that is to say, although the overall impact of authentic areas on the quality of medicinal materials is higher than that of non-authentic areas, the potential has not yet been fully tapped

The high-quality potential of Scutellaria baicalensis is still not maximized, and the quality improvement is not significant

[0016] Third, the standardized production process of Chinese medicinal materials is complicated, the cycle is long, the cost is too high, and it is difficult to implement
