Abstract: The property of mixed solvent composed of 95 %ethanol and hexane (MSEH), the effect of oil-tea camellia seed oil (OCSO)on the mixing solubility of MSEH and the technique of extraction of defatted cake by MSEH were studied .The results showed that with the ratios form 7∶3 to 4∶6 , 95 % ethanol and hexane could be dissolved .Adding OCSO , the mixing soluble temperature was promoted .The maximum solubility of OCSO by MSEH was 14 % or so .The defatted cake was extracted under the following suitable conditions :the extracting temperature , 58 ℃;the MSEH-cake ratio , 2∶1 ;95 %ethanol-hexane ratio , 5∶5 ;the extracting time , 5 hours . The 3.6 g residual oils and 7.0 g thea saponins were retrieved from 100 g defatted cake .
