13. Potential of mangaba (Hancornia speciosa), mango (Mangifera indica L.), and papaya (Carica papaya L.) seeds as sources of bioactive compounds
ABSTRACT The bioactive compounds and the antioxidant capacities of mangaba, mango and papaya oils were investigated. Determinations of fatty acid composition, tocopherol, phytosterols, phenolic compounds profile, total carotenoids, and antioxidant activity were carried out in the oils of mangaba, mango and papaya seeds. The analysis of antioxidant activity w

15. Phytochemical profile, anti-inflammatory, antimutagenic and antioxidant properties of Acrocomia aculeata (Jacq.) Lodd. pulp oil
Abstract Acrocomia aculeata, known as macauba, is extensively distributed in the Southeast and Midwest of Brazil. Macauba fruit is used as food; however, its therapeutic properties are still poorly understood. The goal of the study was to investigate the chemical composition of macauba pulp oil (MPO) and anti-inflammatory, antimutagenic and antioxidant prope

16. Synthesis of 1,2,3-Triazole Derivatives of Hydnocarpic Acid Isolated from Carpotroche brasiliensis Seed Oil and Evaluation of Antiproliferative Activity
Carpotroche brasiliensis is a tree native to Brazil, belonging to the family Flacurtiaceae, whose seeds contain a group of cyclopentenyl fatty acids: gorlic (12%), chaulmugric (27%), and hydnocarpic (48.7%). These compounds are considered the main therapeutic agents in the treatment of leprosy. In the present study, a series of novel triazole compounds were

17. Effect of pumpkin seed oil on cholesterol fractions and systolic/diastolic blood pressure
Abstract Pumpkin seed oil (PSO) is high in unsaturated fatty acids and plant sterols, which have numerous cardiovascular benefits. The study explores the hypothesis by investigating effects of consumption of 1000 mg of PSO on total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), systolic (SBP) and diastolic (DBP) blood pressu

18. CHEMICAL COMPOSITION OF BIOLOGICAL ACTIVE EXTRACTS OF Tapirira guianensis (ANACARDIACEAE)
This work describes the chemical composition of MeOH seeds and flowers extracts of Tapirira guianensis, a known tree that occurs in the Brazilian Atlantic forest. The CH2Cl2 soluble fraction of seeds extract was submitted to chromatographic procedures to obtain a mixture of new alkenyl dihydrobenzofuranoids which were identified as 2-[(10’Z)-dodec-10’-en

19. Profiling the Cymbopogon nardus Ethanol Extract and Its Antifungal Potential against Candida Species with Different Patterns of Resistance
The essential oil of Cymbopogon nardus, citronella, has been extensively studied. However, the chemical and biological properties of the ethanolic extract (EE) of C. nardus have not been evaluated. The aim of this study was to characterize the chemical composition of the EE of C. nardus and its active fraction (FrD). Moreover, the cytotoxic and antifungal pr

20. Chemoenzymatic Synthesis and Anti-Inflammatory Activity of Fatty Acid Amides Prepared from Bertholletia excelsa (Brazil Nut) Triglycerides
This study reports the synthesis of fatty acid amides (FAA), analogous to anandamide, prepared from Brazil nut oil (BNO), using Amano lipase from Pseudomonas fluorescens as a catalyst of direct aminolysis, with a good yield (95-68%). The anti-inflammatory effects of BNO and FAA were evaluated by the carrageenan-induced paw edema method. Analysis of the forma

21. Avocado oil as an inducer of the extracellular lipase activity of Kluyveromyces marxianus L-2029
Abstract Avocado represents one of the most nutritious and consumed foods in Mexico, and its export generates significant profits; because of its fatty acids content, the avocado oil was used as an inducer for the synthesis of extracellular lipases from the non-conventional yeast Kluyveromyces marxianus L-2029. Lipases are able to catalyze acyl glycerides, h

22. Optimization of the extraction of phenolic compounds from olive pomace using response surface methodology
ABSTRACT Extraction of olive oil gives rise to large quantities of pomace and liquid effluents, since on average only 21% of the weight of the olive corresponds to oil, the remaining 79% consists of water, bark, pulp and stone. With the intention to make available new forms of use of this residue, this research was proposed, with aimed to optimize the extrac

23. Impact of whey protein isolate coatings containing different antimicrobial agents on sliced bologna-type sausage during refrigerated storage
Abstract In this study, we aimed to determine the possibility of using the edible whey protein isolates coatings containing different antimicrobial agents on the bologna-type sausage slices and the inactivation effects of these coatings against Listeria innocua. For this purpose, edible whey protein isolates (WPI) coatings were prepared to contain essential

24. Bioactive compounds and value-added applications of cupuassu (Theobroma grandiflorum Schum.) agroindustrial by-product
Abstract Cupuassu is a fruitful species from the Amazon basin with great economical potential, due to the multiple uses of its pulp and seeds in the food and cosmetic industries. This fruit generates large amounts of solid waste, which, despite of its high content of bioactive compounds, is discarded in the environment. Therefore, with the aim of reusing the
