Abstract

The invention relates to the field of traditional Chinese medicine detection technology, in particular to a characteristic spectrum construction method and a quality detection method for bighead atractylodes rhizomes. According to the characteristic spectrum construction method for bighead atractylodes rhizomes, a characteristic spectrum of effective ingredients, namely atractylenolide I, atractylenolide II, atractylenolide III and atractylon of bighead atractylodes rhizome medicinal materials, bighead atractylodes rhizome herbal pieces and bighead atractylodes rhizome herbal pieces stir-bakedwith bran are analyzed through efficient liquid chromatographic analysis, chromatographic peaks of the characteristic spectrum are completely displayed, uniformity is good, the characteristic chromatographic peaks are completely separated, the quantity of impurities is small, a contrast characteristic spectrum is established according to the characteristic spectrum, and meanwhile the content of atractylenolide I and the content of atractylenolide III are determined. In combination with thin-layer chromatography identification and heavy metal and harmful element determination, the comprehensive quality detection method for bighead atractylodes rhizomes with effectiveness and safety is provided, so that quality detection on bighead atractylodes rhizomes, processed products of bighead atractylodes rhizomes and relevant products is realized. Moreover, the quality detection method has the advantages of being simple, fast, stable, reliable, high in precision, good in reproducibility, easy to grasp and the like.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine detection, and in particular relates to a method for constructing a characteristic map of Atractylodes macrocephala and a method for quality detection. Background technique [0002] Atractylodes macrocephala is the dried rhizome of Atractylodes macrocephala Koidz, a plant in the family Compositae. It is a commonly used tonic traditional Chinese medicine in my country. [0003] With the enhancement of people's awareness of health care, people have higher requirements for the quality and safety of traditional Chinese medicine products. At present, the quality standards of Atractylodes macrocephala include simple properties, identification, routine inspection, and determination of extracts, as well as the determination of HPLC fingerprints. Traditional Chinese medicine fingerprint is a comprehensive and quantifiable means of identification, and it is one of the current quality c...
