Abstract:

Objective： This study aims to investigate the correlation between the appearance and color of different types of Cornus officinalis herbs and their quality， and to establish a method for determining the contents of four constituents （gallic acid， mononoside， marsenoside， and swertiamarin） in these herbs.Methods： Five batches of Cornus officinalis samples were collected， classified into categories A， B， and C based on their appearance characteristics such as color， oiliness， and flesh thickness （fullness）. The chromaticity values （L*， a*， b*） of the herbs were measured using a colorimeter， and quality evaluation indicators including moisture， total ash， water-soluble extract， and the contents of the four target components were determined using methods such as drying， total ash test， cold immersion， and HPLC analysis. Data were analyzed using SPSS software.Results： The moisture， total ash， water-soluble extract， and the contents of the target components in all three types of Cornus officinalis met the standards outlined in the 2020 edition of the Chinese Pharmacopoeia. Compared to category C， significant differences in the a* value and water-soluble extract content were observed in categories A and B （P<0.05）， with higher a* values and water-soluble extract contents in the latter.Conclusion： The appearance color of Cornus officinalis herbs is closely related to their water-soluble extract content. A higher redness （larger a* value） corresponds to a higher content of water-soluble extract， suggesting that the quality of Cornus officinalis herbs is positively correlated with the color intensity. The findings of this study provide a reference for the rapid quality assessment of Cornus officinalis herbs.
