OPTIMIZATION OF EXTRACTION PROCESS OF THE LEAVES OF MATES FOR DIFFERENT RAW MATERIAL RATIO TO THE SOLVENT

Mahi LATIFI

Abstract

Leaves of Mate are leaves of the pharmaceutic plant Ilex paraquariensis. Mate is a raw material and is widely used in medicine. Mate leaves are mainly the ones that in its content have important substances, and in this group are Caffeine Theobromine Theophylline, Chlorogenic Acid, and Etheric oil. Long ago the leaves of Mate were used only as ground and mixed with water, known as mate tea, which also has a curative effect. Nowadays, are required standard methods a lot, to get an extract of Mate, so that the dosage is more accurate, on the other side main substances to be standardized and dissolved equally in the extract. There is a possibility even percolation extraction to be used for this because we have leaves, however in this case the extraction is made by maceration using specific conditions, first of all, different rations of raw material and the solvent used for extraction, reduced grinding degree and low concentration of the solvent. Maceration as a form of extraction, allows the main components of Mate leaves to be completely extracted and the extraction coefficient is higher, on the other side technological process is further realized without any problems.
