Study on Pharmacognostic Identification of Four Kinds of Herba Epimedii
Objective:To study the production and marketing status of epimedium from four sources,the pharmacognostic identification of traditional Chinese medicine Epimedium is carried out,in order to provide useful references for the identification of the authenticity and quality of Epimedium.Methods:Apply methods such as pharmacognostic properties,optical microscopy,and thin layer chromatography to study the exclusive and practical identification characteristics of Epimedium.Results:Trait identification showed that there were differences in the number,morphology,texture,and serration of small leaf blades among the four basal sources of Epimedium.Microscopic identification studies showed that there were certain differences in the non glandular hair and protrusion characteristics on the lower surface of the four basal sources of Epimedium;All four sources of Epimedium contain flavonoids.Conclusion:There are certain differences in the non glandular hair and protrusion characteristics on the lower surface of the four basic sources of Epimedium,which can be used as their exclusive identification features and as a new basis for the authenticity identification of traditional Chinese medicine Epimedium in the future;At the same time,there are differences in the number,shape,texture,and serrations of the small leaves of the four basic sources of Epimedium,providing a traditional Chinese medicine basis for their identification.The effective ingredients of Epimedium have fluorescence in ultraviolet light,providing useful reference for the identification of the authenticity and quality of traditional Chinese medicine Epimedium.
