Abstract
Medicinal preparations (pharmaceutical products) based on essential oils are used in the treatment of many diseases. Pepper mint Mentha piperita is one of the most important essential oil crop. Menthol obtained from peppermint oil is included in the preparations Validol, Corvalol, Valokordin, Pectusin, and Menovazine. The demand of the Russian pharmaceutical industry for mint raw materials at the ex-pense of its own production is not fully satisfied. It can be increased by development new high-yielding varieties of mint and developing modern methods of their cultivation. For this purpose, new high-yielding varieties Aisberg and Aromatnaya, differing in essential oil content and component composition, were developed in the conditions of the North Caucasus branch of the All-Russian Research Institute of Medicinal and Aromatic Plants. The variety Aisberg has a high content of oil (4.98%) and menthol in it, while the variety Aromatnaya has a low content of essential oil (1.95%) and a high content of menthone and minor components, which allows these oils to be used in different industries – pharmaceutical, perfumery, cosmetic, and food. The application of natural retardant Hardy on the studied moint varieties promoted the increase of essential oil content in raw material by 22–27% and the increase of biologically active components in essential oil: menthol in the variety Aisberg, menthone in the variety Aromatnaya. To ensure a high yield of mint oil per hectare, the complex application of EcoFus (an organomineral fertilizer) and Siliplant (a silicon-containing microfertilizer) is appropriate at the beginning of plant growth and Hardy (retardant) – in the phase of budding. This method increased the yield of the studied mint varieties by 12–13%, the content of essential oil by 26–29%, and oil yield per a hectare by 41–45%.
