Analysis of technology for plant extract production using the mathematical modeling method

Abstract

Upon receipt of a sedative action liquid extract based on valerian root, motherwort herb, hop seedballs and peony roots by percolation the influence of a number of factors extractant (ethanol) concentration , extraction ratio and infusion time before the extraction process on the yield of extractive substances and active components (hydroxycinnamic acids in terms of chlorogenic acid) has been studied. The studies have been carried out using mathematical planning by a three-phase fractional experiment plan based on a 4x4 Latin square. According to the data obtained, the optimal conditions for the extraction are the use of 70% ethanol, the extraction multiplicity 4, the process of infusion 24 hours before actually percolation.
