Abstract: Caffeine not only is an important composition which makes up of the taste of tea soup, also has pharmacology functions as tonify the heart, diuresis, detoxification, preventing asthma. it is an alkaloid medical material in great demand. Solanesol has the functions as absorb free radical, it also is the intermediate in the synthesis of drugs which can cure cardiovascular disease.In the article, we analyze the composition of tea and tobacco leaf after Supercritica fluid extraction(SFE) extraction, when the rate of determination of caffeine is 85% in tea,which process conditions for the water content of 40%, extraction time to eight hours, the temperature was 50°C. In this condition after the extraction of polyphenols in tea minimal extrusion rate , By the extraction of solanesol crude the content of the initial has reached 21.60%. While after the conditions of its extraction time 2 h, extraction temperature 50°C, the extraction pressure 20 MPa, cosolvent ethanol volume fraction of 95%. Which offer the industrial production experience.
