The method of improving the quality of Scutellaria baicalensis by using sodium dithionite

Abstract

The invention discloses a method for improving the quality of Scutellaria baicalensis by using sodium dithionite, which relates to the technical field of Scutellaria baicalensis. The preparation method is as follows: fresh roots of scutellaria baicalensis→cleaning→drying in the shade at 20-25°C for 1-2 days→spraying active oxygen Carrier → placed at 20-25°C for 3-10 days → dry; the active oxygen carrier is sodium dithionite, the concentration of sodium dithionite is 0.4μmol / L-40mmol / L; the treatment time period is 3-15 day; the temperature is 10-35°C; the present invention plants Chinese herbal medicines in the most suitable plant growth area or in the main production area, and various measures can be taken to increase the yield; according to the nature of the quality of Scutellaria baicalensis, artificially Intervene in the secondary metabolism of fresh medicinal materials, greatly improve the quality of medicinal materials, so as to achieve a double harvest of quality and yield. The invention maximizes the level of secondary metabolism of Scutellaria baicalensis, so that all the medicinal materials produced can reach or exceed the quality of authentic medicinal materials.

Description

[0001] Technical field: [0002] 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. [0003] Background technique: [0004] 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 ...

AI Technical Summary

Problems solved by technology

[0011] 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

[0012] 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

[0017] 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

[0018] 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
