“…Recent research has analyzed other applications of the outer layers of the babassu, including the anti-inflammatory and analgesic properties [26][27][28][29] of the mesocarp, which is also capable of adsorbing various textile industry dyes. 30 Also, the structural features associated with mesocarp and epicarp permit their use as polymeric supports for the immobilization of ethylenesulfide followed by divalent cation removal from aqueous solutions.…”

Os componentes mesocarpo e epicarpo do coco babaçu foram utilizados como novos biossorventes alternativos para remoção do corante têxtil ftalocianina de cobre de soluções aquosas. Esses biopolímeros foram caracterizados por análise elementar, RMN de 13 C no estado sólido, espectroscopia de absorção na região do infravermelho, análise termogravimétrica e difratometria de raios X. Os resultados mostraram que a composição do mesocarpo e do epicarpo é similar à de outros materiais lignocelulósicos e que ambos os componentes são efetivos na remoção do corante têxtil Turqueza Remazol. O modelo cinético de pseudo-segunda ordem resultou no melhor coeficiente de correlação tanto para o epicarpo quanto para o mesocarpo (R 2 = 0,999), com constantes de velocidade de sorção, k 2 , de 0,31 e 1,43 g mg -1 min -1 , respectivamente. Os modelos de Langmuir e Freundlich foram empregados para analisar os dados experimentais em sua forma linearizada. O segundo modelo apresentou melhor adequação para a adsorção do corante Turqueza Remazol com sorção máxima de 1,44 e 2,38 mg g -1 a pH 6,0 para mesocarpo e epicarpo, respectivamente.The mesocarp and epicarp components of the babassu palm tree were applied as novel alternative biosorbents for copper phtalocyanine textile dye removal from aqueous solutions. The natural biopolymers were characterized by elemental analyses, solid state 13 C NMR, infrared spectroscopy, thermogravimetric analysis and X-ray diffractometry. Results demonstrated that the compositions of the mesocarp and epicarp are similar to those of other lignocellulosic materials, and that they were very effective for removal of the textile dye Turquoise Remazol. A pseudo second-order kinetic model resulted in the best fit with experimental data for both epicarp and mesocarp (R 2 = 0.999), providing rate constants of sorption, k 2 , of 0.31 and 1.43 g mg -1 min -1 , respectively. The Langmuir and Freundlich isotherm models were employed for adsorption analysis of the experimental data in their linearized forms. The second model resulted in the better fit for Turquoise Remazol dye, which presented maximum adsorption of 1.44 and 2.38 mg g -1 at pH 6.0 for mesocarp and epicarp, respectively.

“…Numerous factors such as increased vascular permeability, intestinal motility, vagal activity, decreased gastric blood flow and prostaglandin levels play an important role in the pathogenesis of gastric ulcers. Thus, several experimental models can be used in an attempt to elucidate the mechanism of action of plant extracts 4 , 5 , 8 .…”

Background: Peptic ulcer is considered a public health problem associated with loss of quality of life. Does not exist optimal therapeutic regimen. The search for alternative treatments using foods or plants that may assist in gastric protection may become marked in this population because of their easy access and low cost. Aim: To study the antiulcerogenic activity of extracts of Orbignya phalerata (babaçu) and Euterpe edules (juçara) in Wistar rats after induction of peptic ulcer, compared with Omeprazole. Method: Forty Wistar rats were distributed into four groups: group I, II, III, IV (10 rats each) subjected to extract of Orbignya phalerata, Euterpe edules, Omeprazole and ethanol, respectively. Each group of 10 rats was divided into subgroups of five for prophylaxis and therapeutic study. Results: The pre-treatment with juçara extract has provided a significant protection against peptic ulcer induced by ethanol. In the prophylactic subgroup, Omeprazole resulted in protection. In addition to protection against peptic ulcer, inflammation and neocapillarization were also variables with a statistical significance in the prophylaxis subgroups using omeprazole and juçara. In the therapeutic subgroup, omeprazole, juçara and babaçu were statistically different as for protection against the presence of inflammation and the healing of ulcers. Conclusion: The extracts of juçara and babaçu behaved as the omeprazole, evidencing the therapeutic activity of these extracts.

“…The authors observed a potential healing effect based on the animals treated with the extract, which had better results for the tensiometric parameter and more excellent resistance. 84 Under the same conditions, an aqueous extract of babassu mesocarp induced better healing of surgical injuries of the bladder. 85 An apparent circular incision of 2 cm in diameter with a metallic puncture was made in mice.…”
