WASTE PRODUCT OF GROWING THE GENUS ECHINACEA (ECHINACEA MOENCH) AS PROMISING SOURCE OF BIOLOGICALLY ACTIVE SUBSTANCES

Abstract

The experimental foundation bioconversion of waste product of growing (chaff), purple coneflower
(Echinacea purpurea (L.) Moench.) and pale coneflower (Echinacea pallida (Nutt.) Nutt.) was to carried
out. The high activity of extracts of coneflower chaff, which had growth-stimulating effect to the test
culture, was proved. Found that the highest stimulating activity has the extract of chaff purple
coneflowers: aqueous solution at concentrations of 0.01 %, alcohol-0.01 %-0.001 % and with increasing
concentration of alcohol in the extracts decreased their activity. For the first time it has been shown that
chaff of Echinacea contains specific proteins - lectins, and their activity in the waste product of pale
coneflower significantly exceeded then activity in the waste product of purple coneflower. Technological
schemes to get of lectins and extracts of biologically active substances from waste growing product
(chaff), was worked out for their effective use.
