Problems solved by technology

[0003] The traditional method of processing Scutellaria baicalensis is to adopt the method of natural drying, but the drying time is long, the effect is not good, and it is easy to mold, worm, and deteriorate. In the prior art, various methods such as vacuum drying, infrared drying, and microwave drying are also used. Processing, however, the processing process is relatively simple, without considering the loss of various active ingredients, especially baicalein, resulting in relatively low active ingredients in the final product, how to improve the flavonoid content of Scutellaria baicalensis products, especially baicalein, by improving the existing drying technology Content, is the problem that the present invention needs to solve

Abstract

The invention discloses a drying treatment method for radix scutellariae. According to the method, fresh roots of the radix scutellariae are sequentially subjected to moisturizing pretreatment, dehumidification drying, oven drying, microwave drying and other processes; the quality of the radix scutellariae is improved while drying is carried out, and the baicalein content and the total flavonoid content are far higher than those of a product produced through a conventional drying method; and the method is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine processing, in particular to a method for drying and processing Scutellaria baicalensis. Background technique [0002] Scutellaria baicalensis is a perennial herb of Labiatae. Its dried root is used as medicine. It is a commonly used traditional Chinese medicine. Scutellaria baicalensis has antipyretic, antibacterial, sedative, antihypertensive, and transaminase-lowering effects. The main active ingredients of Scutellaria baicalensis are flavonoids such as baicalin, baicalein, wogonin, and wogonin. It has the effects of clearing away heat and dampness, purging fire and detoxifying, stopping bleeding and preventing miscarriage. Among the four flavonoids with higher content in Scutellaria baicalensis, baicalein has the highest bioavailability and the strongest activity, and high baicalein content is also an important symbol of high-quality Scutellaria baicalensis. [0003] The...
