Abstract:
The research aimed to investigate the effects of different ethanol and water ratios on extracting
phenolic, flavonoid compounds, as well as tartaric acid from star fruit, evaluating their inhibitory effect on
tyrosinase activity. The ripe star fruit (Averrohoa carambola) puree was macerated for eight hours with
various ethanol and water ratios of 0:100, 20:80, 50:50, 80:20, and 100:0. Different ratios yielded varied
contents of total phenolic (TPC), flavonoid (TFC), and tartaric acid (TAC). The results showed contents of
8.48-101.50 mg GAE/g FW, 2.33-45.66 mgCE/g FWand 0.0490-0.0939 mg/g FW, respectively. The 50:50 ratio
showed the highest TPC and TFC, whereas the 0:100 ratio had the highest TAC. The efficacy of the extracts
on tyrosinase inhibition, using L-DOPA as a substrate, yielded the IC50 value (54.90-210.37 mg/L). All
extracts exhibited a significant IC50 value (p ≤ .05). The 80:20 ratio demonstrated the most significant
inhibitory activity, showing moderate inhibition of tyrosinase activity. These findings suggest A. carambola
extracts could be valuable in cosmeceuticals ingredient
