| Abstract: |
| Tea saponin was separated from oil-tea camellia seed oil. The extraction process was optimized by single factor experiment and response surface methodology, and the performance of the extracted tea saponin was analyzed and compared with that extracted from oil-tea camellia seed meal. The results showed that the optimal extraction conditions of tea saponin were obtained as follows: with anhydrous ethanol as extractant, ratio of solvent to material 11∶?1,extraction time 1.25 h and extraction temperature 60℃. Under the optimal conditions, the extraction rate of tea saponin was （82.50±0.03）%. IR results showed that tea saponins from oil-tea camellia seed oil and oil-tea camellia seed meal had some differences in structure. The foamability, foam stability and surface activity of tea saponin from oil-tea camellia seed oil were better than those of tea saponin from oil-tea camellia seed meal. |
