Actual aspects of anatomical research of medicinal plant material of Vinca minor L

The article presents the results of a microscopic study of the medicinal plant material Vinca minor L. (Apocynaceae), used in the pharmaceutical industry to obtain indole alkaloids with antitumor activity. When carrying out anatomical analysis of the leaves and stems of V. minor , the main anatomical and diagnostic signs was established, this can be used in the identification and assessment of the authenticity of medicinal plants. Analysis of the anatomical structure showed that the leaves of V. minor are dorsoventral; hypostatic sheet plastic. The stomatal apparatus of plants is paracytic. The main vein of the leaf blade is represented by a bicollateral conducting bundle; lateral leaf veins had closed collateral bundles. The cross-sectional shape of the stem is grooved with four ribs. The stem of V. minor was characterized by a non-bundle type of anatomical structure. The peculiarity of the stem structure was the presence of internal phloem. The characteristic marker features of the stem and leaf of the plant include the presence of straight, non-segmented, non-anastomosing lactic acidae with an excretory substance of a greenish-yellow color. The information obtained can serve as a basis for the development of the section “Microscopy” when writing pharmacopoeial articles.
