RESUMO

Abstract The present study was conducted to evaluate the chemical composition, antioxidant activity and hypoglycemic effects of whole kumquat (Ku) powder in diabetic rats fed a high-fat-high-cholesterol (HFHC) diet. The antioxidant activities were evaluated using stable 1,1-diphenyl 2-picrylhydrazyl (DPPH) free radical scavenging method, 2,2´-azinobis (3-ethyl benzo thiazoline-6-sulphonic acid) radical cation (ABTS) and Ferric reducing antioxidant power (FRAP). Total phenolic content was (51.85 mg GAE/g) and total flavonoid content was (0.24 mg Cateachin Equivalent, CE/g). DPPH and ABTS values were 3.32 and 3.98 mg Trolox equivalent (TE)/g where FRAP value was 3.00 mM Fe2+/kg dry material. A total of 90 albino rats were used in the present study. Rats group were as follows: normal diet; normal treated (2, 4, and 6% Ku.), diabetic rats (non-treated), diabetic + HFHC diet (non-treated), HFHC (non-treated), Diabetic (treated), HFHC (treated) and Diabetic + HFHC (treated). The diets were followed for 8 weeks. Blood samples were collected at the end of the experiment. Serum glucose was recorded and thyroid hormones (T4, Thyroxine and T3, Triiodothyronine) were conducted. Diet supplemented with Kumquat at different concentrations have a hypoglycemic effect and improve the thyroid hormones of both diabetic rats and HFHC diabetic rats.


Resumo O presente estudo foi conduzido para avaliar a composição química, a atividade antioxidante e os efeitos hipoglicêmicos do pó de kumquat (Ku) em ratos diabéticos alimentados com uma dieta rica em gordura e colesterol (HFHC). As atividades antioxidantes foram avaliadas usando o método de eliminação de radicais livres de 1,1-difenil 2-picrilhidrazil (DPPH), 2,2'-azinobis (ácido 3-etilbenzotiazolina-6-sulfônico) radical cátion (ABTS) e antioxidante redutor férrico potência (FRAP). O conteúdo fenólico total foi (51,85 mg GAE / g) e o conteúdo total de flavonoides foi (0,24 mg Cateachin Equivalent, CE / g). Os valores de DPPH e ABTS foram 3,32 e 3,98 mg equivalente de Trolox (TE) / g, em que o valor de FRAP foi de 3,00 mM Fe2 + / kg de material seco. Um total de 90 ratos albinos foi usado ​​no presente estudo. O grupo dos ratos foi o seguinte: dieta normal: tratados normais (2, 4 e 6% Ku.), ratos diabéticos (não tratados), diabéticos + dieta HFHC (não tratados), HFHC (não tratados), diabéticos (tratados), HFHC (tratados) e diabéticos + HFHC (tratados). As dietas foram seguidas por 8 semanas. Amostras de sangue foram coletadas ao final do experimento. A glicose sérica foi registrada e os hormônios tireoidianos (T4, Tiroxina e T3, Triiodotironina) foram conduzidos. A dieta suplementada com kumquat em diferentes concentrações tem um efeito hipoglicêmico e melhora os hormônios tireoidianos tanto de ratos diabéticos quanto de ratos diabéticos com HFHC.

RESUMO

BACKGROUND AND AIMS: During the last decade, there has been a growing interest in replacing synthetic antioxidants by natural ones because they are cheaper and safe. The main aim of this work was to investigate the possible role of carrot, mango, and wheat extracts against carbon tetrachloride (CCl4)-induced oxidative stress and hepatotoxicity. METHODS: Forty albino rats were recruited and divided into 5 groups. Group 1 was fed a basal diet and group 2 was fed a basal diet and CCl4. Groups 3, 4, and 5 were treated with carrot, mango, and wheat extracts, respectively, in addition to a basal diet and CCl4. RESULTS: Hepatocellular toxicity decreased significantly following treatment. Lipid profile and liver enzymes markers decreased remarkably and total protein and high-density lipoprotein (HDL) increased dramatically. The oxidative stress has decreased noticeably through the decrease in Malondialdehyde (MDA). Microscopic examination of the treated rats exhibited a normal histopathological structure. CONCLUSION: These data suggest that carrot, mango, and wheat extracts could be used as nutraceuticals for the prophylaxis and treatment against hepatotoxicity and oxidative stress. This is the first study of its kind that highlights the importance of including such plants in the dairy and food industry for the prevention of hepatocellular toxicity and oxidative stress.
