Abstract

The invention belongs to the field of traditional Chinese medicine analysis, and in particular relates to a method for detecting the quality of magnolia officinalis before and after irradiation; the method obtains the irradiated magnolia officinalis by irradiating the magnolia officinalis; Score and fingerprint analysis. The present invention establishes a common pattern of fingerprints before and after irradiation of Magnolia officinalis, calibrates 18 peaks as common peaks, can effectively characterize its quality, overcomes the singleness of the original quality control method, and has high application value.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine analysis, and in particular relates to a quality detection method of magnolia officinalis before and after irradiation. Background technique [0002] Magnolia officinalis, also known as Zipu, Ziyoupu, Wenpu, etc. in the botanical range, is a plant of Magnoliaceae and Magnolia, and the common ones are Magnolia officinalis (original subspecies) M. .officinalissubsp.biloba two kinds, mainly produced in Sichuan, Hubei and other places. In Chinese medicinal materials, it refers specifically to the dry bark, root bark and branch bark of the plant. From April to June, the root bark and branch bark are stripped and dried directly in the shade. The dried bark is boiled in boiling water and then piled up in a damp place. When the inner surface is "sweaty" until the inner surface is purple-brown or brown, steam it until it is soft, take it out, and roll it into a tube. ,dry. Shredded, ginger is...
