Quality Grading of "Fubaiju" Based on Inflorescence Diameter and Content of Polyphenolic Substances.

ABSTRACT: Chrysanthemi Flos encompasses numerous cultivars. Fubaiju (FBJ) is a subvariety of Hangbaiju introduced from Tongxiang City, Zhejiang Province. Due to the variable quality of FBJ on the market, establishing a standardized grading system is necessary. This study aimed to develop a simple and effective quality grading method for "Fubaiju" by integrating the inflorescence diameter and polyphenol content. The contents of chlorogenic acid, luteolin-7-O-glucoside, and 3,5-O-dicaffeoylquinic acid in 52 FBJ samples were determined by using UPLC-UV. The inflorescence diameter of the samples was measured, and correlation analysis was employed to examine relationships between the inflorescence diameter and polyphenol content. Samples were classified via K-means clustering based o
