Abstract:
This study was conducted to evaluate the Antioxidant act1v1ty (AA) and phenolic
compound of differences part of Hibiscus tiliaceus which was collected around mangrove
area of Pantai Tok Jembal, Kuala Terengganu. The sample were H. tiliaceus matured
leaves, young leaves and bark. Antioxidant activity (AA) of the methanol acetate was
measured using ferric thiocyanate (FTC) mehod and 2,2-diphenyl -1-picrylhdrazyl
(DPPH) method. Phenolic compound was measured by using follin-ciocalteu method.
Methanol acetate were used as extracting solvent. Using FTC method, result show that
matured leaves were the highest antioxidative activity but there ware no significant
different (p<0.05) between all samples. However using DPPH method the result show
that matured leaves were the highest antioxidative activity and there were significantly
different (p<0.05) between all the samples. For phenolic content, result show matured
leaves as the highest compared to all the samples and there are also significantly different
(p<0.05) among the samples. Based on the result matured leaves of H. tiliaceus extract
could be used as accessible source of natural antioxidant.
