Micro-Characteristics and Microscopic Identification of 9 Kinds of Epimedium Leaves
OBJECTIVE To systematically study the micro-characteristics and microscopic characteristics of 9 commercially a-vailable Epimedium leaves,summarize more exclusive and practical features and provide reference for effective identification of Epime-dii Folium on market.METHODS Using the character identification,micro-character identification,microscopic identification and combining with the technique of depth synthesis,high definition feature images of 9 species of Epimedium leaves were obtained.Some of the feature maps were extracted digitally and analyzed by SPSS 26.0 software.RESULTS The micro-characteristics of petiole hair,leaf margin spines,nipple and hairs on lower surface,parenchyma number on the base of leaf main vein transverse section,cuticle on the surface of leaf,as well as the microscopical characters of upper epidermal cell wave depth,non-glandular hair and nipple surface morphology,all of that can be regarded as specific features of 9 species of Epimedium leaves in classification and identification.There was statistically significant difference in the angle of thorns at the edge of leaves,the proportion of wave depth in upper epidermal cells and the density of nipple among all samples(P<0.05).CONCLUSION Nine kinds of Epimedium leaves could be distinguished through the micro-characteristics and micro-identification methods.The quantitative analysis and statistical analysis of micro-property will make up for the deficiency of traditional experience identification by subjective factors.The results of this study will provide a refer-ence for the circulation,inspection,clinical medication and standard drafting and so on.
