| Abstract: | The ethanol-ammonia water extraction of tea saponin from camellia cakes is studied.With ethyl alcohol as the extractant,the effects of extraction times,the content of ammonia water,the content of ethanol,the ratio of feed to liquid,extraction temperature and extraction time are investigated.By orthogonal test L16(45),the optimal extraction conditions are as follows:78℃ of extraction temperature,1∶10(g/mL)of the ratio of feed to solvent,55 min of extraction time,70% of ethanol concentration,0.1% of ammonia water concentration.Under above conditions,and the tea saponin yield reaches 22.41%. |
