“…Amounts of polyunsaturated fatty acids similar to ours were obtained in the study of Silva et al (2009). Their methods of determination based on mass spectrometry (MS) also confirm that oleic (71%) and palmitic acids (20%) are the major fatty acids in Buriti oil, and stearic acid, as well as in our study, was also detected (Bataglion et al, 2015). This small variation in results is predictable and may be influenced by many factors, such as season, extraction and refining processes (Aquino et al, 2012).…”

“…Although, as with the DPPH analysis, comparison of the results of this study with other studies it is inaccurate, and serves only as a reference. No other study assessing the antioxidant activity of Buriti oil without its fractionation was found, but a study that evaluated the ORAC value of the lipophilic and hydrophilic fractions of this oil indicated that the hydrophilic fraction (8.3 μmol TE·g −1 oil), due to synergistic effects of the pool of antioxidants, presents a value almost 5 times higher than the lipophilic fraction (1.8 μmol TE·g −1 oil) (Bataglion et al, 2015). When comparing these results with those obtained in our study, the big difference in the total ORAC (95.3 and 10.1 μmol TE·g −1 oil, respectively) is, as mentioned above, due to the synergistic effect of the different antioxidants present in both non-polar and polar fractions, type of solvent used or even oil characteristics.…”

“…Studies on the antioxidant activity with this oil are also scarce, with results restricted to a single radical (Ferreira et al, 2011;Bataglion et al, 2015). Furthermore, these studies generally evaluate the antioxidant activity of the oil after fractionation by difference in polarity and not the intact oil, which may adversely affect the results obtained (Espín et al, 2000).…”

SUMMARY:Buriti oil is an example of an Amazonian palm oil of economic importance. The local population uses this oil for the prevention and treatment of different diseases; however, there are few studies in the literature that evaluate its properties. In this study, detailed chemical and antioxidant properties of Buriti oil were determined. The predominant fatty acid was oleic acid (65.6%) and the main triacylglycerol classes were tri-unsaturated (50.0%) and di-unsaturated-mono-saturated (39.3%) triacylglycerols. The positional distribution of the classes of fatty acids on the triacylglycerol backbone indicated a saturated and unsaturated fatty acid relationship similar in the three-triacylglycerol positions. All tocopherol isomers were present, with a total content of 2364.1 mg·kg −1 . α-tocopherol constitutes 48% of the total tocopherol content, followed by γ-tocopherol (45%). Total phenolic (107.0 mg gallic acid equivalent·g −1 oil) and β-carotene (781.6 mg·kg −1 ) were particularly high in this oil. The highest antioxidant activity against the free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH) was obtained at an oil concentration of 50 mg·mL −1 (73.15%). The antioxidant activity evaluated by the Oxygen Radical Absorbance Capacity (ORAC) was 95.3 μmol Trolox equivalent·g −1 oil. These results serve to present Buriti oil as an Amazonian resource for cosmetic, food and pharmaceuticals purposes.

El aceite de Buriti es un ejemplo de aceite de palma amazónica de gran importancia económica. La población local utiliza este aceite para la prevención y el tratamiento de diferentes enfermedades; sin embargo, hay pocos estudios científicos que evalúen sus propiedades. En este estudio, se determinaron las propiedades antioxidantes del aceite de Buriti. El ácido graso predominante fue el oleico (65,6 %) y las principales clases de triglicéridos fueron tri-insaturadas (50,0 %) y Di-insaturados-mono-saturada (39,3 %). La distribución posicional de las clases de ácidos grasos en el esqueleto de triacilglicerol indicó una relación de ácidos grasos saturados e insaturados similar en las tres posiciones del triacilglicerol. Todas las isoformas de tocoferol estaban presentes, con un contenido total de 2364.1 mg·kg ) fueron particularmente altos en este aceite. La mayor actividad antioxidante contra el radical 1,1-difenil-2-picrilhidrazil libre (DPPH) se obtuvo a una concentración de aceite de 50 mg·mL −1 (73,15 %). La actividad antioxidante evaluadas por la capacidad de absorción de radicales de oxígeno (ORAC) fue 95,3 mmol Trolox equivalente·g −1 de aceite. Estos resultados presentan al aceite de Buriti amazónico como buen recurso con fines cosmético, alimenticio y farmacéutico.

“…Buriti oil contains β-carotene in higher concentrations than foods widely consumed by Brazilians, such as guava, pitanga, papaya, passion fruit, carrots and other fruits from the Amazon region, including palm nuts, peach palm and tucumã (RodriguezAmaya, 1996;De Rosso and Mercadante, 2007). In addition, buriti oil presents high levels of tocopherols, making it a reliable source of antioxidant compounds (Bataglion et al, 2015).…”

SUMMARY:This work reports a complete characterization of buriti oil. Physicochemical properties were determined according to AOCS methodologies and thermophysical properties were measured using a controlled stress rheometer and a digital electronic density meter. β-carotene and tocopherol contents were obtained using HPLC systems. Fatty acids and acylglycerol classes were determined using GC and HPSEC systems, respectively, while triacylglycerol composition was estimated using the software PrOleos. Thermal behavior (crystallization and melting) was analyzed using a DSC. The results attested high levels of total carotenoids with β-carotene as the major one; total tocopherols contained α-and β-tocopherols which accounted for 91% of the total; and monounsaturated fatty acids were mainly represented by oleic acid. The results showed close agreement between density and viscosity of buriti and olive oils. The crystallization and melting peaks occurred at -43.06 °C and -2.73 °C, respectively. These properties enable Buriti oil to be recommended as an excellent alternative for enriching foods with bioactive compounds. KEYWORDS: β-carotene; Carotenoids; Monounsaturated fatty acid; Oleic acid; Tocopherols; Triunsaturated triacylglycerolsRESUMEN: Parámetros de calidad y comportamiento térmico del aceite de buriti (Mauritia flexuosa L.). En este trabajo realiza una completa caracterización del aceite de buriti. Las propiedades fisicoquímicas se llevaron a cabo de acuerdo con las metodologías AOCS y se midieron las propiedades termo-físicas usando un reómetro de esfuerzo controlado y un medidor de densidad electrónico digital. Se obtuvieron los contenidos de β-caroteno y tocoferol utilizando HPLC. Los ácidos grasos y las diferentes clases de acilgliceroles se determinaron utilizando GC y HPSEC, respectivamente, mientras que la composición de triacilglicéridos se estimó utilizando el software PrOleos. El comportamiento térmico (cristalización y fusión) se analizó utilizando un DSC. Los resultados ponen de manifiesto altos niveles de carotenoides totales con β-caroteno como mayoritario, tocoferoles totales, con α-y β-tocoferoles que representan el 91% del total, y ácidos grasos monoinsaturados representados principalmente por ácido oleico. Hay una estrecha relación entre la densidad y la viscosidad del aceite de buriti y las de los aceites de oliva. Los picos de cristalización y de fusión se dan a -43,06 °C y -2,73 °C, respectivamente. Estas propiedades permiten que el aceite de Buriti sea recomendado como una excelente alternativa para enriquecer alimentos con compuestos bioactivos.

Peripheral nerve lesions are a common cause of disability and may result in loss of motor and / or sensory functions, representing a significant clinical problem with unsatisfactory treatment options. A widely studied alternative in the context of tissue regeneration are the essential oils. The objective of this study was to evaluate the efficacy of Buriti oil associated with therapeutic ultrasound in the functional recovery of rats. There were 18 male Wistar rats (250 and 300g), divided into three groups: control, submitted to ultrasound and another subjected to ultrasound associated with Buriti oil. Subsequently, the right sciatic nerve of rats suffered a controlled injury by strangling a portable device with a dead weight of 5,000g / 10 minutes. Samples were collected before treatment (control) and 24 h, 7, 14 and 21 days after sciatic nerve compression. These tests consisted of filming the gait of each animal on the bottom of the glass walkway and analyzed the IMAGE-J® program. Measurements were the lengths of the legs (left back), and the distance between the toes. It has been shown that the combination of Buriti oil with ultrasound was more effective in neuromotor regeneration of rats after axonomy compared to single ultrasound therapy.
