| English abstract | Peel extracts of litchi and rambutan, and that of tamarind seed coat were investigated in relation to their utility in skin-aging treatments. Standardized extracts of tamarind were significantly ( p < 0.05) more efficient at O 2 •- scavenging (IC 50 = 27.44 ± 0.09) than those of litchi and rambutan (IC 50 = 29.57 ± 0.30 and 39.49 ± 0.52 μg/ml, respectively) and the quercetin standard (IC 50 = 31.88 ± 0.15 μg/ml). Litchi extract proved significantly ( p < 0.05) more effective for elastase and collagenase inhibition (88.29 ± 0.25% and 79.46 ± 0.92%, respectively) than tamarind (35.43 ± 0.68% and 57.69 ± 5.97%) or rambutan (31.08 ± 0.38% and 53.99 ± 6.18%). All extracts were safe to human skin fibroblasts and inhibit MMP-2, with litchi extract showing significantly ( p < 0.01) enhanced inhibition over the standard, vitamin C (23.75 ± 2.74% and 10.42 ± 5.91% at 0.05 mg/ml, respectively). Extracts suppress melanin production in B16F10 melanoma cells through inhibition of tyrosinase and TRP-2, with litchi extract being the most potent, even more so than kojic acid (standard). These results highlight the potential for adding value to agro-industrial waste, as the basis for the sustainable production of innovative, safe, anti-aging cosmetic products |
