Extraction and Determination of Polar Bioactive Compounds from Alfalfa ( L.) Using Supercritical Techniques.

The aim of this research was to select parameters for supercritical extraction with CO of L., considered as functional food, in quarter-technical plant, providing the highest concentration of bioactive polar constituents and simultaneously maintaining the highest efficiency of the process. For the purpose of optimization, mathematical statistics was used.

Supercritical Fluid Extraction of Bioactive Compounds from Plant Materials.

There has been growing interest in the application of supercritical solvents over the last several years, many of the applications industrial in nature. The purpose of plant material extraction is to obtain large amounts of extract rich in the desired active compounds in a time-sensitive and cost-effective manner. The productivity and profitability of a supercritical fluid extraction (SFE) process largely depends on the selection of process parameters, which are elaborated upon in this paper.
