Abstract

Purpose: To investigate the antioxidant and anti-melanogenesis activities of Durio kutejensis check for this species in other resources [Bombacaceae (Hassk.) Becc] fruit extract.
Methods: The fruit flesh of D. kutejensis was extracted successively with n-hexane, ethyl acetate/EtOAc, and ethanol/EtOH at room temperature repeatedly. The extracts were concentrated in vacuo to yield their residues. Antioxidant properties were analyzed by 2,2′-azino-bis(3- ethylbenzothiazoline-6-sulphonic acid) (ABTS, superoxide dismutase (SOD)-like activity, 2,2-diphenyl-1- picrylhydrazyl (DPPH), and oxygen radical absorbance capacity (ORAC) while anti-melanogensis activity was evaluated by tyrosinase enzyme activity and B16 melanoma cell assays (melanin inhibition and cytotoxicity).
Results: The extract (200 μg/mL) showed melanin inhibition by inhibiting melanin formation in B16 melanoma cell by 47 % without cytotoxicity but did not inhibit tyrosinase enzyme activity. The extract (1 - 1000 μg/mL) also exhibited some level of antioxidant activity including ORAC (0.04 ± 0.00 μmol TE/mg at 950 μg/mL), ABTS (1.0 ± 0.2 % at 100.8 μg/mL), SOD (IC50, 76.00 ± 14.6 μg/mL, and DPPH (21.5 ± 0.7 % at 97.39 μg/mL extract concentration).
Conclusion: The fruit extract of Durio kutejensis has antioxidant properties with a potential for treating hyperpigmentation and for use as a skin-lightening agent.
