Problems solved by technology

However, after slicing, the epidermis is destroyed, and the contact surface area between the internal tissue and the external space increases, which instead increases the loss, damage and deterioration of the active ingredients in Danshen during processing.
[0006] In addition, vacuum drying, infrared drying, microwave drying and other methods are also used in the prior art. When the whole ginseng is dried, the disadvantages of uneven water content inside and outside the dry product and loss of active ingredients still exist, and the drying effect is still not ideal. poor overall effect
Moreover, the processing process is complicated, the equipment configuration requirements and cost are high, and it is not suitable for popularization and application.

Abstract

The invention discloses a method for drying harvested red sage root. The method comprises pretreatment, grading, ultraviolet irradiation, airing, jasmonic acid methyl ester spraying, secondary airing and drying. The method dries the medical red sage root, improves red sage root quality, greatly improves active ingredient content of red sage root, realizes uniform and full drying effects, prevents an active ingredient loss caused by high temperature heating and significantly increases active ingredient content of red sage root after drying.

Description

technical field [0001] The invention belongs to the technical field of medicinal material processing, and relates to a post-harvest drying method of salvia miltiorrhiza. Background technique [0002] Salvia miltiorrhiza Salvia miltiorrhiza The dried roots and rhizomes of the herb have the effects of promoting blood circulation, removing blood stasis, dredging menstruation and relieving pain. It is a commonly used bulk medicinal material in clinical practice. It is known as "the largest pharmaceutical industry raw material" and is also a popular medicinal material developed internationally. Secondary metabolites in medicinal plants are usually an important material basis for the clinical efficacy of Chinese herbal medicines. The 2015 edition of "Chinese Pharmacopoeia" stipulates that fat-soluble tanshinone I, tanshinone IIA and cryptotanshinone, and water-soluble salvianolic acid B are As an important index to measure the quality of salvia miltiorrhiza. The 2015 edition of ...
