IDENTIFICATION OF PERMISSIBLE AREAS OF PREPARATION OF MEDICINAL VEGETABLE RAW MATERIALS NEAR TRANSPORT LINES

Abstract

The purpose of the work is to study the permissible distance for the collection of medicinal plant raw materials near transport highways of different degrees of loading. The study was carried out in the Voronezh region on the example of eight different types of medicinal vegetable raw materials (Herring grass bitter, avian mountain grass, five-foot desert grass, plain thousand-year-old grass, double-ground nettle leaves, large planter leaves, common pajma flowers, core lip flowers) Collected in time of procurement along and at different distance from roads and railways of different degree of load in different natural zones, regulated by normative documentation. In the analyzed samples, the content of standardized biologically active substances, as well as heavy metals, pesticides, radionuclides, was previously estimated and full compliance with pharmacopoeia requirements was shown. In this work, the analysis was carried out on the level of ash insoluble in hydrochloric acid in the medicinal plant raw material, which makes it possible to estimate contamination of the raw material with dust particles. On the basis of the obtained data using the mathematical simulation method, the permissible distances from the transport lines, which can be recommended for the collection of safe medicinal plant raw materials, have been identified: Distance from major roads and highways loaded by road in forest natural zone conditions – at least 230 m, in forest steppe zone conditions – at least 300 m, in steppe zone conditions devoid of wood and shrub vegetation, – Not less than 660 m, near non-high-speed roads characterized by low traffic load – not less than 160 m, near railway lines – not less than 130 m. The obtained results can be recommended for safe collection of medicinal vegetable raw materials.
