OBJECTIVE To explore the characteristic and microscopic features of Perillae Folium and Perillae Folium sum Cacumen and provide reference for the identifiication of Perillae Folium and Perillae Folium sum Cacumen.METHODS Char-acteristic identification and microscopic identification of 6 batches of Perillae Folium and Perillae Folium sum Cacumen were car-ried out.Samples were collected at different growing stages,including seeding stage,vegetative growth stage and reproductive stage.RESULTS For Perillae Folium collected at different growthing stages,the transverse sections of leaf veins were com-pared.As plant grows into older stages,more areas of the leaf veins appeared purple color.Additionally,the color of excited luminescence varied between Perillae Folium collected at different growing stages.These phenomena could be utilized to differen-tiate between Perillae Folium collected at different growing stages.Next,this experiment explored the microscopic difference of Perillae Folium and its counterfeit,Perillae Folium sum Cacumen.The leaf surface characters of Perillae Folium and Perillae Folium sum Cacumen were found to appear in different shapes.The density of peltare glandular hair and capitate glandular hair,as well as the numerical value of stomatal index ratio(lower/upper surface),was observed to be different between two kinds of leaves.CONCLUSION Through this experiment,the characteristic and microscopic features of Perillae Folium and Perillae Folium sum Cacumen are summarized,offering a reference for the supervision inspection,clinical application and standard revision of Perillae Follium.
