Relationship Between Characters and Main Components of Chelidonii Herba Pieces / 中国实验方剂学杂志

ABSTRACT

Objective:To determine the relationship between the characters and the main components of Chelidonii Herba pieces. Method:The main components of the samples were determined by HPLC, and the characters of Chelidonii Herba Pieces were evaluated by sensory evaluation. The correlation between the characters and components was calculated by correlation formula. Result:The content of 6 components, such as chelidonine, was determined by HPLC. Based on the result of sensory evaluation, there was a certain correlation between the characters and the components. Character descriptions that " some have visible white powder, some have white pubescence, and sometimes they have visible yellow florets" had a very low similarity with total alkali, indicating that these characters and total alkali content was not related. The similarity between the description of " hollow stem" had a high similarity with total alkali content, indicating that the amount of stem was related to the total alkali content. The character description of " more broken leaves" was negatively correlated with total alkaloids in the similarity, which indicated that the content of total alkaloids was less when there were more leaves(or more broken leaves), otherwise, the content of total alkaloids was relatively higher. Conclusion:The established HPLC method is simple and feasible. This study objectively quantifies the descriptions of Chelidonii Herba pieces characters, correlates them with the main components of Chelidonii Herba pieces, and then preliminarily judges the quality of Chelidonii Herba pieces according to the appearance of the characters, which provides a theoretical basis for the identification of Chelidonii Herba pieces in the market by experience, and ideas for the study of the characters of other traditional Chinese medicines.
