The aim of this work was to compare the antioxidant activity of the peel and pulp extracts of Garcinia tinctoria (yellow mangosteen) fruits. Total phenolic content (TPC) assay showed that the peels contained higher phenolic content than the pulps. Ferric reducing antioxidant power (FRAP) test indicated that the peel extract of G. tinctoria fruits showed a highest antioxidant capacity, and reached a maximum value of 2,7 μM at 10 μg/mL. Peel extract of G. tinctoria fruits exhibited higher scavenging activity of DPPH radical in comparison with the pulp extract, due to the lowest value of IC 50 (48,8 μg/mL). The TPC results showed a good relationship with the radical scavenging activity obtained for the pulps and peels extracts.

Abstract
The aim of this work was to compare the antioxidant activity of the peel and pulp extracts of Garcinia tinctoria (yellow mangosteen) fruits. Total phenolic content (TPC) assay showed that the peels contained higher phenolic content than the pulps. Ferric reducing antioxidant power (FRAP) test indicated that the peel extract of G. tinctoria fruits showed a highest antioxidant capacity, and reached a maximum value of 2,7 μM at 10 μg/mL. Peel extract of G. tinctoria fruits exhibited higher scavenging activity of DPPH radical in comparison with the pulp extract, due to the lowest value of IC 50 (48,8 μg/mL). The TPC results showed a good relationship with the radical scavenging activity obtained for the pulps and peels extracts.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
