| Summary: | Asthma-plant contains high amount of kuersitrin flavonoids so it is potential as a
new source of flavonoids. This research’s objective is to develop the method of
kuersitrin’s enrichment by using macroporous resin, which is known to be safer,
eco-friendly, economics, and efficient. Evaluations were conducted over
performance characteristics and separation of macroporous resin in respect to
kuersitrin’s enrichment and the adsorption and desorption of the macroporous resin
in respect to kuersitrin. Result shows the process of macroporous resin’s adsorption
and desorption in respect to the amount of kuersitrin in the extract was following
first order model which means the process of adsorption is not affected by the other
compounds. The examination of the isothermic adsorption shows a congruence to
Freundlich’s model (R2= 0.9850) than Langmuir’s (R2= 0.4334). On the optimal
condition, the enrichment of kuersitrin by using macroporous resin increased the
purity and content to 4.72 times which was from 3.60% in the extract to 17.02% by
percentage of recovery as 50.39%.
