This research is a fragment of complex studying of grades of laurels of the noble, growing in the territory of botanical gardens of Pyatigorsk medical and pharmaceutical institute and the Nikitsky botanical garden which is carried out based on department of botany and a pharmacognosy of the Pyatigorsk medical and pharmaceutical institute. Introduction: Research objective is to conduct a comparative morphological and anatomical research of leaves of 6 sorts of Laurus nobilis. Material and Methods: The exemplars of leaves of 6 grades of laurels noble, growing in the territory of the Nikitsky botanical garden (the settlement of Nikita, Crimea republic). When carrying out comparative morphometric, micromorphological, histochemical methods. Results: The comparative morphometric research of a leaf plate is conducted, at the same time the form of a leaf plate, character of a top, basis and margined of a leaf plate were estimated. In the analysis of features of a micromorphological structure carried out the analysis of an anatomic structure of scapes of leaves and a structure of a transversal cut of a sheet plate, a top and bottom epidermal of a sheet plate. The form of the cross- section of the petiole is horseshoe-shaped, dredging is absent or falciform with the expressed dredging, rounded triangular form, dredging is absent. The presence or absence of coverage trichomes, the presence only at the top party of a scape and it is presented by individual monocelled lengthiest hairs, is presented by a small amount of individual, monocelled small hairs on the top party of a petiole it is presented by individual monocelled small hairs. Existence and arrangement of a resin ducts are presented in big quantity, especially there is a lot of around a phloem part of a vascular bundle or the ducts are presented in a great many, there is a lot of them, both around a phloem part of a vascular bundle, and under epidermis. Existence and arrangement of a sclerenchyme \–around the vascular bundle from two parties or it is presented by groups of fibers around the vascular bundle or absent. Conclusion: As for an anatomic structure of an epidermis of a leaf plate, differences in a histological structure of an epidermis of the studied grades of laurels noble it is not revealed. The following signs are characteristic of all studied exemplars: leaf plate of hypostomatic type. Stomates are present only at the lower part of an epidermis. The stomatal type is anomocytic. Epidermal cages of the lower epidermis have the extended form with sinuous anticlinal walls. Anticlinal walls of the main cages of the top epidermis have the reference uniform thickenings In the analysis of features of a micromorphological structure carried out the analysis of an anatomic structure of scapes of leaves and a structure of a transversal cut of a sheet plate, a top and bottom epidermal of a sheet plate.

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.
