THE TECHNOLOGY OF OBTAINING OF A SUBSTANCE FROM THE WASTE OF PROCESSING OF THE HYPERICUM PERFORATUM GRASS, WHICH POCESS OF GROWTH-STIMULATING ACTIVITY

The stage of drying of the mother liquor after extraction of flavonoids by ethyl acetate of the substance "Dry extract of Hypericum perforatum " was developed, on the basis of this the preparation "Zversin" with growth-stimulating activity was developed. It was found that drying of the "Zversin" using a spray dryer is optimal. As a result of the study of the influencing parameters on the drying process, the following mode was selected, which ensures the optimum operation of the dryer with a high yield of the final product: the temperature of the heat-transfer at the inlet of 160–170 °C, the outlet of 60–70 °C, the feed rate of the solution is 5.5 l / h∙m3, the dry residue of the solution is 10-15%. The influence of the "Zversin" to the germination of seeds, the growth and development of plant seedlings has been studied. On the basis of the obtained results, the technology for the complex processing of St. John's wort has been developed, which allows to obtain substances for the treatment of depressive conditions and plant growth regulator. At the test technology, it was found that the yield of dry extract (content of total hypericins is 0.3%) yielded to 2.0%, "Zversin" (rutoside content is 6%) – yielded to 7% to the weight mass of raw material.
