ABSTRACT Two related underutilized plants from breadfruit (Artocarpus altilis) and breadnut (Artocarpus camansi) were explored for their antioxidant and toxicity potential. Maceration with water was employed for the sake of safety and easiness. Various parts of both plants, namely leaves, fruit peel, anthocarp, and breadnut achene, were investigated. The antioxidant assays employed in this study were total phenolic and flavonoid content, total antioxidant capacity, DPPH scavenging activity, power-reducing assay, and linoleic acid peroxidation inhibition. The acute toxicity potential of the extracts was assessed using inhibition of Vibrio harveyi bioluminescence. The EC50 value determined from the toxicity assessment (>2.4 mg/mL) was higher than the concentrations of all extracts used in the various assays of antioxidant property. From all aqueous extracts, the best results in terms of highest antioxidant activity and relatively lowest toxicity were obtained for breadnut leaves, breadnut achene, and breadfruit leaves.

面包果和面包果各部位水提物的抗氧化和毒性活性

摘要 研究了面包果 (Artocarpus altilis) 和面包果 (Artocarpus camansi) 中两种相关未充分利用的植物的抗氧化和毒性潜力。为了安全和容易，用水浸渍。研究了这两种植物的不同部分，即叶子、果皮、花果树和面包果瘦果。本研究中采用的抗氧化试验是总酚类和类黄酮含量、总抗氧化能力、DPPH 清除活性、功率降低试验和亚油酸过氧化抑制。使用哈维弧菌生物发光的抑制来评估提取物的急性毒性潜力。从毒性评估中确定的 EC50 值 (>2.4 mg/mL) 高于在各种抗氧化性能试验中使用的所有提取物的浓度。
