The chemical composition and functional effects of mangaba fruit pulp were evaluated through a multi-endpoint assay in mice, consisting of the bone marrow micronucleus test, gut micronucleus test, and the apoptosis, oxidative stress, and comet assays. Mangaba fruit pulp was administered in three doses, 10, 20, and 40ml/kg body weight (b.w.), by gavage to male Swiss mice against doxorubicin and dimethylhydrazine-induced mutagenicity. The phenolic profile of the mangaba fruit pulp was evaluated by HPLC, and seven compounds were identified: gallic acid, catechin, chlorogenic acid, vanillic acid, o-coumaric acid, rosmarinic acid, and rutin. The in vivo tests revealed that mangaba fruit pulp showed no toxic/mutagenic effects in any of the assays performed, and also showed protective effects at all endpoints. At the three administered extract concentrations, the main results about the protective effects were as follows: bone marrow micronucleus test (42.33, 58.14, and 77.21%), micronucleus gut test (34.21, 63.15, and 78.07%), and apoptosis index (57.5, 43.68, and 65.52%). This study provides scientific evidence for the antimutagenic potential of mangaba fruit pulp and emphasizes its potential as a functional food with widespread applicability in the food industry.
通过对小鼠进行多终点试验,包括骨髓微核试验、肠道微核试验、凋亡试验、氧化应激试验和彗星试验,评估了曼加巴果果肉的化学成分和功能效果。以10、20和40毫升/千克体重(bw)三种剂量,通过灌胃法给雄性瑞士小鼠施用曼加巴果果肉,以对抗阿霉素和二甲基肼诱导的致突变性。通过高效液相色谱法评估曼加巴果果肉的酚类成分,鉴定出七种化合物:没食子酸、儿茶素、绿原酸、香草酸、邻香豆酸、迷迭香酸和芦丁。体内试验表明,曼加巴果果肉在任何所进行的试验中均未显示出毒性/致突变作用,并且在所有终点均显示出保护作用。在三种施用的提取物浓度下,关于保护作用的主要结果如下:骨髓微核试验(42.33%、58.14%和77.21%)、肠道微核试验(34.21%、63.15%和78.07%)以及凋亡指数(57.5%、43.68%和65.52%)。本研究为曼加巴果果肉的抗诱变潜力提供了科学证据,并强调了其作为功能性食品在食品工业中广泛应用的潜力。
