Abstract:
[Objective] To observe the effect of tea saponin purified by macro-reticular resins,optimize the technique conditions.[Method] To screen the best macro-reticular resin in terms of adsorption rate,capacity and desorption rate.Orthogonal test was used to observe the effect of pH,time,concentration and volume ratio of resin to solution on adsorption.[Result] YWD01G2 was best resin for adsorption.Its optimum conditions were pH6~7,time 8h,concentration 0.05g/mL,ratio 1:1.5.The saponin content reached 82.3% in elution of 50% ethanol.[Conclusion]Saponin content could be significantly promoted by macro-reticular resin adsorption.The technique was brief and practicable.
