This study aimed to assess the nutritional value and effect of flowers on induced anemia in rats. Proximate composition and minerals analysis were performed using AOAC standard methods. Twenty-five rats were randomly divided into five groups. Rats in Group 1 were healthy and non-anemic. In Group 2, the rats were anemic and untreated. Anemic rats in Group 3 were given 5 mg/Kg of a reference drug (Apfer) against anemia. Rats in Groups 4 and 5 were anemic and fed with flower powder (5% substitution) harvested in Dschang and Yabassi. Anemia was induced in rats using 2,4-Dinitrophenyl hydrazine. After 23 days of treatment, some hematological and biochemical parameters as well as indicators of oxidative stress were evaluated. The results show that potassium, calcium, and phosphate were the main minerals present in flowers. Concerning proteins (21.29% ± 1.13%) and lipids content (8.99% ± 0.72%), flowers harvested in Dschang were the most nutritive. Calcium was more available in flowers harvested in Dschang. These flowers are the potential sources of carotenoids with around 2201.33 and 2535.04 mg/100 g, harvested in Dschang and Yabassi, respectively. The main metabolites identified were alkaloids, quinones, anthocyanins, triterpenes, and saponins, and this profile was not affected by the locality. flowers significantly ( 0.05) increased hematocrit, hemoglobin, and red blood cells in Groups 4 and 5 compared to Group 2. Supplementation of flower significantly ( 0.05) increased lipid profile in Groups 4 and 5 when compared to Groups 2 and 3. Also, the activity of superoxide dismutase (SOD) and catalase (CAT) significantly ( < 0.05) increased in Groups 4 and 5 compared to Groups 2 and 3. Consumption of flowers could therefore help to prevent and fight against hemolytic anemia and oxidative stress.
本研究旨在评估花朵对诱导大鼠贫血的营养价值及影响。采用美国官方分析化学家协会(AOAC)标准方法进行近似成分分析和矿物质分析。将25只大鼠随机分为五组。第1组大鼠健康且未患贫血。第2组大鼠患贫血且未接受治疗。第3组贫血大鼠给予5毫克/千克的抗贫血参考药物(Apfer)。第4组和第5组大鼠患贫血,分别喂食在贾恩和亚巴西采集的花朵粉末(替代量为5%)。使用2,4 - 二硝基苯肼诱导大鼠贫血。治疗23天后,评估一些血液学和生化参数以及氧化应激指标。结果表明,钾、钙和磷是花朵中存在的主要矿物质。关于蛋白质(21.29%±1.13%)和脂质含量(8.99%±0.72%),在贾恩采集的花朵营养最丰富。钙在贾恩采集的花朵中更易获取。这些花朵是类胡萝卜素的潜在来源,在贾恩和亚巴西采集的花朵中,类胡萝卜素含量分别约为2201.33和2535.04毫克/100克。鉴定出的主要代谢产物为生物碱、醌类、花青素、三萜类和皂苷类,且该成分不受产地影响。与第2组相比,第4组和第5组的花朵显著(P<0.05)提高了血细胞比容、血红蛋白和红细胞数量。与第2组和第3组相比,第4组和第5组补充花朵后显著(P<0.05)改善了血脂水平。此外,与第2组和第3组相比,第4组和第5组中超氧化物歧化酶(SOD)和过氧化氢酶(CAT)的活性显著(P<0.05)增强。因此,食用花朵有助于预防和对抗溶血性贫血及氧化应激。
