Polygonum orientale decoction and preparation method and content and characteristic chromatogram detection method thereof

Abstract

The invention relates to the technical field of traditional Chinese medicines, in particular to a polygonum orientale decoction, a preparation method thereof and a content and characteristic chromatogram detection method. The invention provides the preparation method of the polygonum orientale decoction, indexes and parameters such as a pretreatment method, decoction times, water addition amount, decoction time and the like are limited, and proper low-temperature concentration and freeze drying are adopted, so that effective component groups of traditional Chinese medicines are reserved to the maximum extent. The invention also provides a polygonum orientale decoction detection method which is used for determining the total content of orientin and isoorientin in a polygonum orientale standard decoction, and the result has the advantages of good separation effect, high sensitivity, good reproducibility and the like. The method for detecting the specific chromatogram of the orientale smartweed decoction is provided, the specific chromatogram of the orientale smartweed standard decoction is established, a quality control means is provided for the orientale smartweed decoction product, the variety characteristics of orientale smartweed are considered, misjudgment of part of qualified batches in large-scale production can be avoided, and important quality control parameters can be provided for a large-scale production process. Therefore, the product quality and the quality control level are improved.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to a Chinese herbal decoction and its preparation method, content and characteristic map detection method.

Problems solved by technology

At present, there is no determination method for the content of Hongcao decoction. The detection method and characteristic map detection method of Hongcao decoction are quite different from those of Hongcao medicinal materials and other preparations, mainly because Hongcao decoction is extracted and frozen with water. Dry process can restore and retain the decocting effect of medicinal materials to the greatest extent. This decoction can be used as a standard preparation to measure the whole process of formula granule production. Therefore, the inspection methods for the content determination and characteristic map of this decoction should be simple Strong consistency, specificity and repeatability, and the current detection methods cannot achieve the desired results
