Abstract:
Roots and rhizomes of Vinca herbacea Waldst. et Kit, were collected during early flowering and fruiting. Рhenophases biologically active substances I and II were obtained by liquid-liquid extraction. Dominant alkaloids: tabersonin, reserpine, maidine, norfluorocurarin and copsinin were obtained after the dispertion in citrare-phosfhate buffer and subsequent TLC. Accelerated restitution of granulocytopoiesis was observed in mice during both irradiation and myelotoxic drug-induced acute leucopenia. Increase in total WBC over 200% was observed after treatment by substance I in drug-induced leucopenia model (fivefold oral administration) and over 130% after treatment by substance I in irradiate mice (fivefold intraperitoneal administration). Morphological and anatomical structures of the underground organs of V. herbacea have been studied. The main microstructural characteristics are revealed - Rhizomes are characterized by coutinized epidermis, lamellar collenchyma, fibers and the texture of the vascular system of a monocyclic structure. The root system shows the whole cortex, the endoderm with Kaspar spots; the outer, radially continuous phloem tissue is located in the conducting system and distinguishes the cylindrical xylem tissue with annular and spiral-circular blood vessels.
