Assessment of the prospects for using pharmacopoeial plants of the Trans-Baikal territory

The work represents a preliminary stage of resource studies of the Daurian part of the Trans-Baikal Territory. The XIVth edition of the State Pharmacopoeia of the Russian Federation (2018) includes 102 species of medicinal plants, of which 30 species are found in the Trans-Baikal Territory. Using methods of approximate evaluation of the stocks of medicinal raw materials, we tentatively divided pharmacopeial species into three utilization groups: ten species can be harvested for the needs of the regional pharmacies, eight species can be collected for domestic use by local population, and only five widespread species (Pinus sylvestris L., Betula pendula Roth, Padus avium Mill., Vaccinium vitis-idaea L., Ledum palustre L.) can be used as a resource for the chemical and pharmaceutical industry of the Russian Federation. The remaining species Arctostaphylos uva-ursi (L.) Sprengel, Vaccinium myrtillus L., Carum carvi L., Dryopteris filix-mas (L.) Schott are found in sporadic locations, and Glycyrrhiza uralensis Fisch., Rhodiola rosea L., Convallaria keiskei Miq. is included in the 2017 Red Data Book of the Trans-Baikal Territory. Harvesting of these species is prohibited. It has been established that for the resource studies the most promising are 15 medicinal plant species, and the most promising locations are Yablonovay Range and Argun Dauria floristic regions due to the greatest diversity of pharmacopoeial medicinal plants there.
