【 摘 要 】

In this study, a phytochemical analysis and in vitro analysis of antioxidant assay conducted for two different types of fruit peels extract which are pomelo peel (PP) and pineapple peel (PIP). For phytochemical analysis, total phenols content (TPC), total flavonoids content (TFC) and total tannins content (TTC) and for antioxidant assay, DPPH radical scavenging activity and ferric reducing ability power (FRAP) were determined using spectrophotometric methods. From the analysis, it was found that PP extract rich in TPC, TFC, TTC, DPPH antioxidant scavenging activity and FRAP assay compared to PIP with the values 6.3133 mg GAE/g of extract, 4.6675 mg QAE/g of extract and 0.1593 mg GAE/g of extract respectively. For antioxidant assays, PP extract showed higher percentage of antioxidant scavenging activity compared to PIP extract with 54.95% and also the increase in FRAP when the concentration of extract increased. Thus, PP was chosen to be conducted in a green synthesis of nanoparticles which can be applied in either pharmaceutical or environmental fields.
