Abstract

Natural active molecules extracted from plants, have more and more importance in various industries (food, pharmaceutics, and cosmetics). Classic extraction processes seem to be unable to get high yields high quality, and effective kinetics. Détente Instantanée Contrólée (French, for instant controlled pressure drop) DIC technology allows realizing Essential Oil and Active materials extraction by direct instant auto vaporization; highly reducing energy consumption and improving quality of extracted molecules. DIC can generally modify the technological aptitude of natural material vis-à-vis normal extraction processes by intensifying the extraction process in both terms of kinetics and yields. Eugenia polyanta ((Wight.) Walp))Leaves (daun Salam), has long been used as herbal medicine for antihyperglycaemic treatment, and a Id of studies has also been conducted Eleven trials of DIC were used in the previous study, and the optimum yield was found in for 1.9 MPA and 10.86s. In this research the number of cycles and the optimum extraction conditions (extraction processing time and temperature, concentration of ethanol in the solvent) were studied Extraction condition is optimized at 80°C for 4.5 hours and using 80% ethanol as the solvent. Two cycles were sufficient to obtain great yields of Total Phenol and Flavonoids contents. Starting from 7 cycles, thermal degradation is detected In terms of energy, time consumption, and of the qualities of the herbal extract, DIC process is more beneficial to apply.
