Description:
Context: Premature aging usually occurred due to free radicals reducing
the skins’ physiological functions. Muntingia calabura, a plant containing
rich antioxidants, has the potential to overcome this problem.
Aims: To evaluate the antioxidant capacity of M. calabura in inhibiting
the premature aging process, to be potentially developed into an
antiaging active ingredient.
Methods: The samples were extracted using ethanol 96%, and processed
into n-hexane, ethyl acetate, and ethanol fractions, respectively. Total
phenolic content was determined, followed by the evaluation of
antioxidant capacity through DPPH, FRAP, and ABTS assay. Further,
anti-elastase was conducted using human neutrophil elastase as a skin
degradation enzyme, followed by an anti-collagenase test. Finally,
normal cell proliferation was also evaluated via the MTT method
measuring cell viability on HDFa cells.
Results: As the results, ethanol extract, ethyl acetate fraction, and ethanol
fraction showed a strong antioxidant effect, having great capacity
reducing DPPH, ABTS radicals, and also iron reduction, in contrast to nhexane fraction that exhibited only weak activity. The antioxidant trend
capacities were found directly correlated to total phenolic contents.
Furthermore, the ethyl acetate fraction was found to have optimum
activity in inhibiting elastase and collagenase enzymes, showing a
similar impact on cell viability.
Conclusions: The ethyl acetate fraction from M. calabura exhibits the
prospect for further development to support its effectiveness as an
active ingredient in antiaging cosmetics.
