Abstract
This study aimed to assess the nutritional value and effect of Colocasia esculenta flowers on induced anemia in Wistar 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 C. esculenta 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 C. esculenta 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. C. esculenta flowers significantly (p < 0.05) increased hematocrit, hemoglobin, and red blood cells in Groups 4 and 5 compared to Group 2. Supplementation of C. esculenta flower significantly (p < 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 (p < 0.05) increased in Groups 4 and 5 compared to Groups 2 and 3. Consumption of C. esculenta flowers could therefore help to prevent and fight against hemolytic anemia and oxidative stress.
期刊介绍：
Food Science & Nutrition is the peer-reviewed journal for rapid dissemination of research in all areas of food science and nutrition. The Journal will consider submissions of quality papers describing the results of fundamental and applied research related to all aspects of human food and nutrition, as well as interdisciplinary research that spans these two fields.
