Abstract
In this article results of morphological and anatomical research Laurus nobilis L. are resulted. These plants are growing in the conditions of culture in the Botanical garden of Pyatigorsk medical and pharmaceutical institute (Northern Caucasus region). Introduction: Laurus nobilis L. is grown up as a decorative species in Europe, RUSSIA, the USA and other countries. Chemical composition of the leaves is characterized by essential oil components, sesquiterpene lactones, phenolic and other compounds. Material And Methods: Micro morphological research of vegetative bodies was carried out with the help of a well-known technique. We carry out morphological and anatomical research of a leaf blade and a petiole of a leaf of a plant, which is grown up in a Botanical garden in the Pyatigorsk medical and pharmaceutical institute. Results: The diagnostic characteristics of a leaf blade necessary for an establishment of authenticity of raw materials are revealed. The leaf is hypostomal, dorsoventral, stomatal apparatus of paracytic type. The idioblasts with the essential oil are obtained between mesophyll cells. Idioblasts thin-walled, large enough. In the field of the main vein under an epidermis the collenchyma of lamellar type in 4-7 layers settles down. The leaf petiole on cross-section section has the saddle-like form, without a ledge on the abaxial side of leaf. Under an epidermis the parenchyma settles down, is presented by live cells of the roundish or oval form. Between parenchyma cells it is possible to observe numerous cells-idioblasts with contents of yellow colour. Conclusions: As diagnostic signs of leaf (a leaf blade and a petiole) it is possible to consider numerous cells - idioblasts with an essential oil, the leaf is hypostomatical, dorsoventral, stomatal apparatus of paracytic type. The idioblasts with the essential oil are obtained between mesophyll cells.
