Optimization of extraction technology of total flavonoids from water extract of Qinlian Zhengji Formula
The purpose of this paper is to study the extraction technology of total flavonoids from water extract of Qinlian Zhengji Formula.The water extraction method was used in the experiment,and the extraction rate of total flavonoids in Qinlian Zhengji Formula was taken as the index.The effects of soaking time,extraction temperature,extraction times,extraction time and material-liquid ratio on the extraction rate of total flavonoids in Qinlian Zhengji Formula were investigated by single factor experiment and orthogonal experiments.The optimum extraction process of total flavonoids in Qinlian Zhengji Formula water extract was as follows:soaking time of 0h,extraction times of 1 time,extraction temperature of 90℃,extraction time of 60min,and material-liquid ratio of 1∶20.The highest extraction rate of total flavonoids in Qinlian Zhengji Formula water extract was 6.76％.
