Optimization of the Water Extraction Technology of Flavonoids in Emilia Sonchifolia (Linn.) DC

Abstract:

Single factor experiments and orthogonal experiments were successively carried out to optimize the water extraction technology of flavonoids in Emilia sonchifolia (Linn.) DC. The results showed that the influential order of factors was extraction times >solid-liquid ratio >extraction time. The optimum conditions were 15:1 of solid-liquid ratio, 2h of the extraction time and 3 of the extraction times. Under these conditions, the extraction yield of flavonoids from Emilia sonchifolia (Linn.) DC was 3.35%.
