Open publisher page 0 citations

Abstract

Extraction conditions of flavonoids from cactus using orthogonal design was studied.The suitable levels of ethanol concentration,extraction temperature,extraction time and ratio of material to solvent were determined using one-factor experiment,and orthogonal design was used to optimize the extraction condition.The results show that the optimum conditions were 90% ethanol,ratio of material to solvent 20/1,temperature 55 ℃ and extraction time 1 h.
