Abstract:
AIM:To study the optimum extraction process of total flavonoids in Alsophila spinulosa(Hook.) Tryon and technological parameter of macroporous resin. METHODS: The optimum parameters were chosen by ratio of total flavonoids as the assessment index such as static and dynamic adsorption of macroporous resin. RESULTS: The optimum extracting process conditions were as follows: solvent was ethanol,ratio of solid-liquid was 1(∶)12,extraction time was 1 h,temperature was at(80 ?C).The optimum technological conditions of the D104 were: the solution concentract at 1.36 mg/mL,the current velocity of adsorption 2 BV/h,the amount of saturated adsorption at 5 BV,the eluting reagent 70% ethanol,the eluting velocity 3 BV/h,eluent volume at 2 BV. CONCLUSION: The process can separate and concentrate the total flavoionds of Alsophila spinulosa(Hook.) tryon.
