Impact of electric voltage on the intensification of the extraction process of phenolic compounds from medicinal plant raw materials

The purpose of the study. The presented results of the study show the possibility of intensifying the extraction processes of phenolic compounds from medicinal plant raw materials under the influence of electric voltage.

Material and methods. Studies have been conducted on the effect of electric current on the efficiency of extraction of flavonoids from Thyme herb as a result of the application of alternating and constant voltage. The determination of the flavonoid content was carried out using differential spectrophotometry, rutin was used as a standard sample. In the course of the study, the effects of alternating voltage of 5 V in the frequency range of 10-3-105 Hz and constant voltage in the range of 1.5-12 V were studied.

Conclusion. It has been found that the electrical voltage has a different effect on the extraction of phenolic compounds from Thyme herb. It is proved that the effect of electric voltage increases the efficiency of flavonoid extraction compared to pharmacopoeia methods. The use of electric voltage allows extraction without increasing the temperature, which is a positive factor for the extraction of substances in their native form.
