Effect of the consumption on buriti oil on the metabolism of rats induced by iron overload

Abstract

Objectives:To compare the effect of the consumption of buriti oil and soybean oil on the metabolism of rats under stress induced by iron overload. Materials and methods: A total of 28 rats were randomized into control groups who consumed diet added of soybean (CS) or buriti oil (CB) and gavage with saline and two experimental groups who consumed diet added of soybean (ES) or buriti oil (EB) and daily gavage with iron II sulfate as stress inducer. The fatty acid profile of diets was analyzed. Body weight and diet consumption were evaluated every two days. The lipid profile and liver weight of animals were evaluated at the end of the experiment. Results: Diet added of soybean oil showed higher percentage of polyunsaturated fatty acids (45.6%) and diet with buriti oil was rich in monounsaturated fatty acids (66.9%). There were no differences in food intake, total cholesterol, HDL-cholesterol and LDL-cholesterol among groups (p > 0.05). However, animals fed with diet supplemented with buriti oil showed intermediate triglyceride levels (CB: 65 mg/dL; EB: 68.7 mg/dL) compared to ES group (102.5 mg/dL). The liver of rats from the CS group had higher weight (2.06 ± 0.2 g) compared to the CB group (1.56 ± 0.1 g). Conclusion: Buriti oil consumption was able to minimize some changes related to iron overload. Arch Endocrinol Metab. 2015;59(5):422-7

Supercritical Fluid Extraction from Aguaje (Mauritia Flexuosa) Pulp: Overall Yield, Kinetic, Fatty Acid Profile, and Qualitative Phytochemical Profile

“…Several properties are attributed to Aguaje oil, such as its antimicrobial activity [19], regulation of iron accumulation [20], antiplatelet and antithrombotic activities [21] and antimutagenic effect [8]. In these studies, these properties are attributed to fatty acids and carotenoids.…”

Antibacterial effect of the hydroalcoholic extract of Mauritia flexuosa leaves on gram-negative and gram-positive bacteria

“…In the food industry, the shell and the endocarp of the Mauritia flexuosa fruit are usually discarded or underused for the preparation of sweets, ice creams, juices, jams, infant food and oils 6 . Some studies have emphasized the pharmacological potential of these parts, which contain bioactive compounds, to play a role in antimicrobial defense [7][8][9] , lipid metabolism 10 , hypoglycaemia 11 and curative activities 12 . Mauritia flexuosa also produces secondary metabolites belonging to chemical groups, such as alkaloids and cyanogenic glycosides, and non-nitrogenous compounds, such as tannins, flavonoids, terpenes and anthocyanin 13 .…”
