摘要
美洲西门尼亚(铁青树科)。甜牡荆。(马鞭草科)和凤仙花。(番荔枝科)是生长在干燥的非洲大草原上的三种特有果树。这些品种生产的果实具有独特和高度赞赏的感官特征(香气和风味)。然而,它们的消费仅限于发现它们的地方。此外,关于它们的技术和营养潜力的科学资料很少,这是它们增值的一个障碍。为了弥补这一差距,对来自这些物种的整个果汁的抗氧化潜力进行了比较评估。对果实进行理化表征后,采用DPPH、ABTS、FRAP和TAC等方法测定果汁的抗自由基能力和还原活性。理化分析结果表明,塞内加尔沙蚕的蛋白质含量为7.65±0.99%、总糖含量为32.81±1.08%、灰分含量为3.98±0.17%,与美洲美洲沙蚕的蛋白质含量为5.68±0.17、总糖含量为42.45±1.54%、总糖含量为2.03±0.2%、总糖含量为2.97±0.74%、总糖含量为33.62±1.79%、总糖含量为1.36±0.19%相反。总酚和类黄酮含量分别为1.22±0.01和0.36±0.03 g/100 g FW,高于美洲葡萄(731.93±2.25和295.58±1.67 g/100 g)和唐菖蒲(633.18±1.93和111.09±2.44)。senegalensis和x.a americana对DPPH的抗自由基活性最高(12.50±0.01),高于doniana和维生素C标准(8.33±0.02)。多尼亚巴和塞内格尔巴果汁的ABTS值为14.28±0.01,美洲巴果汁的ABTS值为9.90±0.01,维生素C标准值为6.66±0.02。美洲葡萄汁对TAC的还原能力最高(570.67±1.14 mg EAA / 100 g FW),多尼亚葡萄汁(521.15±1.93)和塞内加尔葡萄汁(147.78±2.75)高于美洲葡萄汁(521.15±1.93)。FRAP测定结果显示,FW含量为1401.04±1.82 mg/100 g,与美洲弧菌(798.79±1.51)和多氏弧菌(600.19±2.37)相反。FRAP (r=0.86)和DPPH (r= 0.96)对黄酮类化合物抗氧化活性有显著影响。单宁(r = 0.98)与TAC测试密切相关。
Evaluation of Antioxidant Potentialities of Whole Fruit Juices from Ximenia americana Linn., Vitex doniana Sweet. and Annona senegalensis Pers
Ximenia americana Linn. (Olacaceae)., Vitex doniana Sweet. (Verbenaceae) and Annona senegalensis Pers. (Annonaceae) are three endemic fruit species growing in dry African savannahs. The fruits produced by these species have unique and highly appreciated organoleptic characteristics (aromas and flavors). However, their consumption is limited to the localities where they are found. In addition, the rarity of scientific information on their technological and nutritional potentials constitute an obstacle to their valorization. To bridge this gap, a comparative evaluation of the antioxidant potential of the whole fruit juices from these species was carried out. After physicochemical characterization of the fruits, anti-radical power and reducing activity of the juices were determined using DPPH, ABTS, FRAP and TAC methods. The physicochemical analyses of A. senegalensis indicated values of 7.65 ± 0.99 % (proteins), 32.81 ± 1.08 % (total sugars), 3.98 ± 0.17 % (ash) in opposite to 5.68 ± 0.17 (proteins), 42.45 ± 1.54 % (total sugars), 2.03 ± 0.2 % (ash) of X. americana and 2.97 ± 0.74 % (proteins), 33.62 ± 1.79 % (total sugars), 1.36 ± 0.19 % (ash) of V. doniana. The A. senegalensis juice had the highest total phenolic and flavonoid contents respectively 1.22 ± 0.01 and 0.36 ± 0.03 g/100 g of FW compared to X. americana (731.93 ± 2.25 and 295.58 ± 1.67 g/100 g respectively) and V. doniana (633.18 ± 1.93 and 111.09 ± 2.44 respectively). A. senegalensis and X. americana had the highest anti-radical activities by DPPH (12.50 ± 0.01) compared to V. donianaand vitamin C standard (8.33 ± 0.02). The ABTS test for the juices from V. doniana and A. senegalensis (14.28 ± 0.01) was compared to X. Americana (9.90 ± 0.01) and vitamin C standard (6.66 ± 0.02). Juices from X. americana had the highest TAC reducing capacity (570.67 ± 1.14 mg EAA / 100 g of FW) compared to V. doniana (521.15 ± 1.93) and A. senegalensis (147.78 ± 2.75). The FRAP test indicated values of 1401.04 ± 1.82 mg/100 g of FW in opposite to X. americana (798.79 ± 1.51) and V. doniana (600.19 ± 2.37). Flavonoids are strongly correlated to antioxidant activity by FRAP (r=0.86) and DPPH (r = 0.96). Tannins (r = 0.98) are strongly correlated with the TAC test.
