Caracterização física e química de folhas, frutos e sementes do bajuru (Chrysobanalus icaco, l.) e avaliação do chá dessas folhas em camundongos (swiss) normais e diabéticos

Abstract

The native fruits represent important resources in the feeding of populations. Many of them as abajeru lack of technician-scientific information that support the extration and the sustainable development of these species in the producing regions. The cocoplum is owned by chrysobalanaceae family and its founs in areas of sandbank.Folk medicine credits the tea leaves of a potent hypoglycemic effect. However, the consumption of fruit is small and there are no reports on the use of seeds.The scarcity of information the lack of evidences of the hypoglycemic effect motivated the accomplishment of this work that had for objective to determine the physical and chemical characteristics of leaves, fruits seeds and oil seeds beyond evaluating the effect of the tea in mice (swiss) normal and diabetic. The analytical determinations revealed that 100g of fruits contains high text of humidity (84.40 g ± 0.15 g), low acidity, low protein content (0.68 ± 0.01 g) and lipids (0.85 ± 0.07 g), low caloric value (64,09kcal) and profile of amino acids and faty acids irrelevants.It also contains interesting amounts of minerals such as calcium (289.30 mg), iron (12.60 mg), copper (1870.0 mg), chromium (890.00 mg) and selenium (59.00 g).The seeds presented in 100g low text of humidity (22,46±0,03) and high concentration of lipidss (45,50±0,10) and calories (532,90Kcal). Its oil had similar proportion of saturated and unsaturated, density of 0.9278, acid value of 1,86±0,62mgKOH. g-1, peroxide value equal to 3.81 mEq kg-1, iodine index of 107 11 gI2 100g-1 and saponification equal to 180 mgKOH. g-1. In addition to solid fat content at 10 ° C equal to 33.60% with soft trim curve showing where the 45 º C is no longer observed in solid fat. The leaves were dried to complete the analysis presented in 100g moisture equal to (10.46 ± 0.27 g), and content consistent with herbal protein (10.53 ± 0.14 g) and ash (4.61 ± 0.13). The microbiological analyses had indicated that the procedure carried through for the users for the collection and hygienic cleaning did not eliminate the contamination risk, having been reduced it when the leves had been dealt with 0,01ppm of metabissulfito of sodium before the dehydration process. The tea at 2,5% and 5% ad libitum showed significant reduction in blood glucose levels in diabetic animals with a bigger reduction as increase of concentration, without causing alteration in normal animals. The diabetic animals showed typical symptoms of diabetes such as weight loss, change in coat ande change in healing. In addition, the state of diabetes tea comsumption did not cause any change in weight and size of heart, right kidney and liver. The results suggest the use of the fruit as good source of antioxidant minerals, beyond provinding to greater knowlegde about their nutritional value with contribuites for its insertion in the tradiotional diet, as well as, motivates the commercialization and manufacture of products made of coco plum. The seed oil coco-plum turned out to be a pormising source of research, since the analisys further indicated the possibility of using this oil in food, can be aplied in the formulation of various products. The tea leaves coco-plum applied in concentrations shown beneficial effects in the control and prevention of hyperglycemia in diabetic animals.
