“…This study demonstrated that S. coronata seed oil is a rich source of medium-chain fatty acids, which could be suitable for biomedical applications (cosmetic and pharmaceutical industries), as showed by Leal et al (2013). Our data are in agreement with the work of Bauer et al (2013), which showed that saturated fats with high levels of medium-chain fatty acids (such as lauric and myristic fatty acids) are prevalent in kernel and fruit oil of S. coronata collected in Bahia, Brazil. These authors commented that this composition is very similar to coconut oil.…”

Syagrus coronata (Mart.) Becc. (Arecaceae) is a native Brazilian palm (ouricuri) and despite the use of its derived products by traditional communities, few scientific reports have been published regarding its biomedical activity. This study investigates the chemical composition and anti-Staphylococcus aureus effects of both manufactured oil (SCO) and essential oil (SCEO) from S. coronata seeds. SCO was provided by rural inhabitants, while SCEO was obtained by hydrodistillation. Chemical characterization was performed by gas chromatography-mass spectrometry (GC/MS). In vitro antimicrobial activity was determined against 17 S. aureus strains, including multidrug-resistant strains. Eleven compounds were detected in the SCEO, octanoic (28.61%) and dodecanoic acids (22.97%) were the major constituents. On the other hand, nineteen fatty acids (FA) were identified in the SCO, the major ones were dodecanoic acid (41.58%) and 9-octadecenoic acid (23.81%). Both oils showed strong activity against all tested strains. Most strains (68.75%) were sensitive to SCEO at minimum inhibitory concentrations (MIC) between 0.002 and 0.01 μL/mL; and minimum bactericidal concentrations (MBC) ranging from 0.002 to 0.312 μL/mL. SCO inhibited the growth of 52.94% of strains with MIC between 0.16 and 0.625 μL/mL. MBC values for SCO were between 0.16 and 5 μL/mL; however, 47.05% of isolates were killed by 2.5 μL/mL of SCO. These results encourage further research into the toxicological and pharmacological aspects of SCO and SCEO. Such work would likely support their use in the development of new antimicrobial agents for the pharmaceutical, food and cosmetic industries.

“…that may have played a role in the lower intake associated with dietary licuri. High concentrations of MCFAs has been reported for licuri [4]. The MCFA have physical properties (lower melting point) similar to unsaturated fatty acids, which increase cellular membrane fluidity.…”

“…On the other hand, a 17% inclusion of licuri has been reported to improve feed conversion and to increase ADG [3], and no changes in the dry matter intake (DMI) of lambs was observed with 16% inclusion of licuri cake [1]. In addition, the fatty acid profile of licuri oil is different from traditional oil sources; it is highly saturated, with high percentages of medium chain fatty acids (MCFA), mainly lauric and myristic acids [4]. Fat is commonly used to increase the energy density in animal diets; thus, licuri may be used for this purpose.…”

The aim of this study was to determine the effect of dietary ground licuri on lamb performance. Methods: Forty male lambs were used in a completely randomized design to test the effects of 0, 5, 10, and 15 g/kg of ground licuri added to diets. The trial lasted for 75 days. Intake, digestibility, physically effective neutral detergent fiber (peNDF), and chewing activity were estimated. Blood samples were taken on day 45 to determine the concentrations of glucose, urea, non-esterified fatty acids (NEFA), and triglycerides (TG). Average daily gain (ADG) were determined on the last day of the experimental trial. Results: Licuri inclusion markedly increased dietary neutral detergent fiber (NDF) and ether extract (EE) content, but it decreased dry matter (DM) intake. However, the intake and digestibility of EE linearly increased. The ADG decreased linearly (p<0.05) with licuri inclusion. Licuri had no effect (p>0.05) on the concentrations of blood metabolites; however, blood urea increased (p<0.05), while serum glucose decreased (p<0.05). Conclusion: The physically effective fiber of ground licuri is similar to Tyfton hay and licuri inclusion decreases lamb performance due to a decreased in DM intake.

“…Vegetable oils are those obtained from parts of plants, such as seeds, nuts, flowers and fruit pulp, and vegetables and legumes mainly formed by lipids. They are the most produced have a high amount of antioxidant compounds [7 -9] and palm kernel oil has a large amount of saturated fatty acids [10,11]. These different compositions allow vegetable oils to be applied to various products.…”

Background:The investigation of new sources of raw materials and the knowledge of the composition of the food is fundamental for the evaluation of their potential and the availability of nutrients for the consumer population.Objective:This work aimed to deepen the knowledge about the crude oil of babassu fruit obtained by two different methods of extraction, cold pressing and extraction by cooking the fruit almond.Method:Total phenolic compounds contents and antioxidant activity were determined by ferric reducing antioxidant potential assay and 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity assay. By liquid chromatography, the content of different bioactive compounds was determined. Data was submitted to Analysis of Variance (ANOVA) and compared by f test (p <0.05).Results:The results showed that for most of the bioactive compounds there was no difference between the two types of babassu oil. For those compounds where the oils differed, the virgin oil had about three times the content of the extra-virgin oil. In addition, the antioxidant activity was higher for the oil extracted by cooking of the babassu mass, ranging from approximately 2.5 times higher up to 19.2 times higher than the antioxidant activity of the babassu oil extracted by pressing.Conclusion:The process of extraction by cooking the almond mass can incorporate a larger number of bioactive components and improve the antioxidant activity of the virgin babassu oil. However, the extraction method does not influence the content of tocopherols of distinct types of babassu oil.
