摘要: Pre-dispersed solvent extraction (PDSE) was used to extract quercentin from its diluted
solution. Theinfluences of temperature, phase volume ratio (PVR), concentration of sodium
Dodecyl benzene sulphonate andpH value etc. on the extraction efficiency were examined. It
is found that, compared with traditional extractiontechniques under the same condition, a
higher extraction productivity can be obtained by PDSE. The stabilityof colloidal liquid
aphrons plays an important role in this process. In a certain scope, the extraction
efficiencyincreases with PVR. Excessive amount of solvent is not much helpful. A new
analytical method by using ultravioletspectrometer to determine the concentration of
quercentin is established.
