Novel processing method of radix Szechuan salviae miltiorrhizae

Abstract

The invention provides a novel processing method of radix Szechuan salviae miltiorrhizae, and belongs to the technical field of radix salviae miltiorrhizae processing. The method comprises the following steps that firstly, strips of fresh radix Zhongjiang salviae miltiorrhizae are dug out, radix strips which have good quality and grow robustly are selected, sediments and stains on the surface of the radix salviae miltiorrhizae are cleaned away, water is drained after cleaning, air drying is conducted to remove moisture on the surfaces of the radix strips, the strips of the radix salviae miltiorrhizae are put into a slicer for slicing, slices of the radix salviae miltiorrhizae after slicing are put into a sterile tray and placed in order, the tray is put into a lyophilizer, and 17 stages are set for running, wherein the total consumed time is 60.05-90.05 hours, the first 10 stages are cooling and icing stages, the last 7 stages are heating stages, vacuum sterilization is adopted for cooperation, through the stages from low temperature to normal temperature, in cooperation with the function of vacuum, active ingredients of the radix salviae miltiorrhizae can be 100% maintained without loss, and through the combination of low-temperature freezing and normal-temperature drying, the active ingredients cannot be killed; in addition, through the cooperation of the sterilization effectat the low temperature, vacuum and normal temperature, the produced slices of the radix salviae miltiorrhizae are high in quality.

Description

technical field [0001] The invention relates to the technical field of salvia miltiorrhiza processing, in particular to a new processing method of salvia miltiorrhiza. Background technique [0002] Salvia miltiorrhiza is a perennial herb of the genus Salvia in the family Lamiaceae. It is named "Salvia miltiorrhiza" because its dry roots and rhizomes are red and shaped like ginseng, also known as blood ginseng, purple salvia and red salvia. [0003] Salvia miltiorrhiza is a common bulk medicinal material in China, which has antipyretic, antibacterial, sedative, antihypertensive, and antitransaminase effects. The production area of ​​high-quality medicinal materials is usually the sub-distribution area of ​​plants, which is not the most suitable growth area, so the unfavorable environment of high-quality medicinal materials affects the increase of yield. That is, high-quality producing areas are generally not high-yielding areas. Secondly, under cultivation conditions, the g...

Problems solved by technology

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

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 of the overall quality of medicinal materials

[0005] Traditional methods of processing Danshen generally include sun-drying, drying, and shade-drying. The biggest problem is the loss of active ingredients and the killing of active ingredients.
