Circassion walnut (Juglans regia L.) - a valuable medicinal plant that preparations have antimicrobial, general strengthening effects. The problem of authentication of walnut’s raw material has not been examined in detail. Particulary, the available data of the epidermal structural features of leaves and structure of walnut leaf’s mesophyl do not allow to make adequate identification and detection of impurities especially among closely related species. For the first time ever petiole features of walnut introduced in the Samara region have been studied. The features of the structure of the rachis of walnut compound leaf on the different sections in the basal , medial and apical parts have been identified. Also the features of anatomical and histological structure of the compound leaf petioles have been examined. Findings allow us to revise and add the existing part «Microscopy» in the pharmacopeial article on herbal drugs “Circassion walnut leaf”.
