This research aims to evaluate the antioxidant capacity of Dendrocalamus asper extracts from different parts of the plant grown in An Giang province, Vietnam, under agricultural conditions. The study utilized leaves, culms, and roots of Dendrocalamus asper, which were extracted using hot water and ethanol through reflux extraction. The antioxidant capacity of the extracts was assessed using the DPPH assay. The results revealed that the extracts from various parts of Dendrocalamus asper exhibited different levels of antioxidant activity, with the ethanol extracts showing the highest activity. The root ethanol extract showed the highest activity (600 mg/ml), followed by the culm extract (534,976 mg/ml) and the leaf extract (476,066 mg/ml). Additionally, the study found that ethanol extracts had higher free radical scavenging activity compared to water extracts.
