Optimization of Ion Precipitation Conditions for Separation of Quercetin from Fructus Forsythiae
摘要
Abstract
In order to develop a method for the separation of quercetin from ethanol extract from Fructus Forsythiae, the effects of precipitant dose, temperature and stirring time on quercetin yield were explored. The final product was analyzed by HPLC using quercetin standard. The results showed that the adding 0.60 g of sodium carbonate and 1.00 g of zinc acetate and stirring for 40 min provided a quercetin yield of 4.20% from the 60% ethanol extract from 4.00 g of Fructus Forsythiae. The resulting precipitate showed an HPLC profile similar to that of quercetin standard.关键词
