Preparation method of radix pseudostellariae extract

Abstract

The invention belongs to the technical field of the extraction of radix pseudostellariae, and particularly discloses a preparation method of a radix pseudostellariae extract. The preparation method comprises totally six steps of pretreatment of fresh radix pseudostellariae, two-section steam explosion treatment, hot-water extraction, extracting solution CO2 treatment, three-stage filtration and detoxication. A two-section steam explosion technique in the preparation method not only relatively well achieves an extraction pretreatment effect of radix pseudostellariae, but also quite well achieves an enzyme deactivation purpose of fresh radix pseudostellariae; meanwhile, a process can also reduce and even remove toxic substances generated in steam explosion; as fresh tassel-removed radix pseudostellariae is adopted as an extraction raw material, not only can a drying processing working procedure of radix pseudostellariae be omitted, a cost be decreased obviously and much time be saved, but also the pollution of harmful microorganisms in drying and storage procedures can be furthest reduced; the preparation method provided by the invention is extremely applicable to the preparation and the production of the radix pseudostellariae extract, which are carried out by an enter in a source area of radix pseudostellariae; a new way is provided for the deep processing of radix pseudostellariae.

Description

technical field [0001] The invention belongs to the field of preparation of effective substances of heterophylla, and in particular relates to a preparation method of an extract of heterophylla. Background technique [0002] Pseudostellaria ginseng was first recorded in "Materia Medica Congxin". It is the root of the caryophyllaceae plant ginseng. It is mainly produced in Fujian, Jiangsu, Anhui, Shandong and other provinces. The 2010 edition of "Chinese Pharmacopoeia" describes that Radix Pseudostellariae is sweet, slightly bitter, and flat in nature; it belongs to the spleen and lung meridian; Insufficient yin, spontaneous sweating, thirst, dryness of the lungs. Pseudostellariae is a variety listed in the "list of items that can be used in health food" promulgated by the Ministry of Health. The research on the chemical composition of Pseudostellariae Pseudostellaria shows that Pseudostellariae contains amino acids, sugars, glycosides, phospholipids, cyclic peptides, fatty ...

AI Technical Summary

Problems solved by technology

In addition, the current extraction of Pseudostellaria Pseudostellaria is concentrated on dried Pseudostellaria Pseudostellaria as the raw material for extraction, and there is no report on the effective extraction of Pseudostellaria Pseudostellariae from fresh ginseng. Fresh ginseng as the raw material for effective extraction can not only save the process of drying and processing Pseudostellaria ginseng, significantly reduce costs, save a lot of time, but also minimize the pollution of harmful microorganisms during drying and storage
