| Abstract: | A macroporous resin AB-8 was used to separate and purify the flavone compounds from the shell of wild water chestnut. The results showed that the equilibrium could be achieved after one hour. The saturated adsorption was 89.2 mg/g and the maximal absorbency was 78.4 percent. The desorption of flavone compounds was 82.3 percent when 70 percent ethanol was used as the desorption solvent while the flow speed of ethanol was 10 mL per minute and the amount of sample was 0. 0525 gram. |
