| Abstract: | Objective] To supply help for extracting tea saponin from Fujian camellia leaves and stems and broadening the source of tea saponin.Method] With Fujian Quanzhou camellia leaves and stems as material,the effects of ethanol concentration,liquid-solid ratio,time,temperature on extraction of tea saponin were studied through single factor test and orthogonal test.Result] The effects of various factors on extraction of tea saponin from camellia leaves were shown as liquid-solid ratio,ethanol concentration,extraction temperature,extraction time.The optimum technical extraction conditions were as follows： liquid-solid ratio was 9∶1 ml/g,ethanol concentration was 80%,the extraction temperature was 60 ℃ and the time was 2 h,the extraction rate is more than 13%.From camellia stems were shown as liquid-solid ratio,extraction temperature,ethanol concentration,extraction time.The optimum technical extraction conditions were as follows： liquid-solid ratio was 9∶1 ml/g,ethanol concentration was 80%,the extraction temperature was 70 ℃ and the time was 2 h,the extraction rate is more than 17%.Conclusion] The optimum extraction technology of tea saponin from Fujian camellia leaves and stems was confirmed. |
