Objectives : This study is designed to clarify whitening, anti-inflammatory effect of fractions extracted from the mixture of Phaseolus radiatus L. and ethanol.
Methods : In this experiment, we were intended to reveal whitening, anti-inflammatory effect of fractions extracted from the mixture of Phaseolus radiatus L. and ethanol. The whitening activity was confirmed by UV blocking activity, tyrosinase inhibiting activity, and melanin formation inhibiting activity. Anti-inflammatory activity is confirmed by measurement of cytotoxicity level by MTT assay and measurement of Cytokine expression, which is the main mediator of inflammation reaction.
Results : As a results, overall activity was high in the ethyl acetate fraction. Tyrosinase inhibitory activity was less than 20% at all concentrations, but the activity to inhibit melanin self-production was higher than that of ethyl acetate fraction at 32.19 ± 2.79% at 100㎍/㎖. And ethyl acetate fraction had a relatively high UV blocking activity. In the anti-inflammatory test, the concentration-dependent activity was shown, and the chloroform and ethyl acetate fractions showed significant NO production inhibitory activity. Cytokine expression was superior to that of the final stage of B cell differentiation, and cell viability was over 80% except for the chloroform fraction at the concentration of 200㎍/㎖.
Conclusions : The results of this experiment confirmed the whitening effect and anti-inflammatory effect of Phaseolus radiatus L.‘s extracts and fractions and report the possibility of application as external medicine.
