To investigate the antioxidant properties of mesocarp and endocarp peel extracts from Durian Kampung (DK) and Musang King (MK), researchers from Universiti Putra Malaysia conducted a study. The research aimed to compare their total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activities using standard analytical methods.
TPC and TFC were measured using the Folin-Ciocalteu and aluminum chloride colorimetric methods, respectively, while antioxidant capacity was assessed via DPPH radical scavenging and FRAP assays. Results showed that DK peel extracts—particularly the endocarp—had significantly higher TPC and TFC compared to MK. DK endocarp also exhibited stronger antioxidant activity based on lower DPPH IC50 values and higher FRAP values, though FRAP differences between varieties were not statistically significant.
Correlation analysis revealed a strong inverse relationship between TPC/TFC and DPPH IC50 values, and a moderate positive correlation with FRAP values. These findings indicate that phenolic and flavonoid compounds contribute notably to the antioxidant potential of durian peel extracts.
This study suggests that durian peel, especially from the DK variety, has promising antioxidant properties and could be explored as a potential source of nutraceutical ingredients. Further research is encouraged to explore its application in functional food development.
