|
This study aimed to investigate the phytochemicals and antioxidant properties of Syzygiumcumini(L.) Skeels grown in
Telur BaganKedah, Malaysia Syzygiumcuminiwas extracted successively in 5 different solvents which are petroleum ether,
toluene, ethyl acetate, acetone, and water, using sequential cold percolation method. The dried crude
extractswerecharacterized for percentage yield, total phenolic content, total flavonoid content, percentage of DPPH
radical scavenging activity, and reducing power to reduce Fe3+ to Fe2+ using FRAP assay.Extracts from different solvents
produced different results. Toluene extract had the highest percentage yield, and highest total phenolic content,
whereas acetone extract had the highest total flavonoid content. Water extract had the highest antioxidant capacity
using DPPH test, with value of 11.89 ± 1.14 mg AEAC/g of dried leaves and reducing power from FRAP assay with value
of 4512.83 ± 287.73 µg AAE/g of dried leaves. Petroleum ether had the highest antioxidant capacity in terms of
inhibitory concentration of DPPH, due to its lowest IC50 value.All the phytochemical and antioxidant properties of
Syzygiumcumini were successfully documented, analyzed .
