Avocado (Persea americana) is a widely consumed fruit and rich source of nutrients phytochemicals. Its industrial processing generates peels seeds which represent 30% the fruit. Environmental issues related to these wastes are rapidly increasing likely double, according expected avocado production. Therefore, this work aimed evaluate potential hexane ethanolic peel (PEL-H, PEL-ET) seed (SED-H, SED-ET) extracts from as sources neuroprotective compounds. Minerals, total phenol (TPC), flavonoid...
Jabuticaba (Plinia cauliflora) and jambolan (Syzygium cumini) fruits are rich in phenolic compounds with antioxidant properties, mostly concentrated the peel, pulp, seeds. Among techniques for identifying these constituents, paper spray mass spectrometry (PS-MS) stands out as a method of ambient ionization samples direct analysis raw materials. This study aimed to determine chemical profiles seeds jabuticaba fruits, well assess efficiency using different solvents (water methanol) obtaining...
Myracrodruon urundeuva Fr. Allem. (Anacardiaceae) is a tree popularly known as the “aroeira-do-sertão”, native to caatinga and cerrado biomes, with natural dispersion ranging from Northeast, Midwest, Southeast Brazil. Its wood highly valued overexploited, due its characteristics such durability resistance decaying. The diversity of chemical constituents in aroeira seed has shown biological properties against microorganisms helminths. As such, this work aimed identify profile volatile...
Ginger is a plant whose rhizome has high therapeutic potential in combating various diseases due to the action of several its constituents. The 6-gingerol, phenolic compounds and carotenoids, act on macrophage modulation, antiplatelet aggregation immunosuppressive activity. This work aimed determine total antioxidant capacity as well evaluate use paper spray mass spectrometry obtain fingerprints ginger samples conventional organic cultivation. results demonstrated that farming showed higher...
The incorporation of Cerrado fruits in food products such as ice cream has many advantages because it represents a source nutrients and bioactive compounds. Given the demand for less laborious methods to analyze food, paper spray ionization mass spectrometry technique was applied first time rapid characterization chemical components found cagaita cream. PS-MS positive negative modes were used. profile volatile compounds determined by headspace solid-phase microextraction combined with gas...
A cagaiteira (Eugenia dysenterica) pertencente à família Myrtaceae, é uma árvore nativa do Cerrado brasileiro, o seu fruto muito frágil, apresentando casca fina e polpa suculenta, consumido na forma processada como geleia para prolongar a vida útil. O presente trabalho teve objetivo elaborar de cagaita avaliar alteração compostos bioativos voláteis em relação in natura. análise espectrometria massa por paper spray nos modos positivos negativos permitiu identificação 27 compostos, dentre...
The characterization of plant compounds with pharmacological activity is a field great relevance in research and development. As such, identification techniques the goal developing new drugs or even validating bioactive properties extracts must be explored order to further expand knowledge extract composition. Most works this employ HPLC, when exploring non-structural cell wall carbohydrates from
Pereskia aculeata Miller, is an unconventional food plant native to South America. This study aimed investigate the influence of different ultrasonic extraction times (10, 20, 30, and 40 min) on phytochemical profile, antioxidant antibacterial activities ethanolic extracts obtained from lyophilized aculeate Miller (ora-pro-nobis) leaves, under-researched plant. Morphological structure chemical group evaluations were also conducted for P. leaves. The resulted in distinct phenolic content...
The Cerrado, the world's most biodiverse tropical savanna, has had 25% of its native vegetation devastated in recent years. family Arecaceae, commonly known as palm trees, is one ethnobotanical families present this biome. They are well for their fruits with antioxidant, anti-inflammatory and hypocholesterolemic characteristics. It estimated that there about 6,000 species plants but only 30% them fully to benefits potentials. Therefore, objective study perform an integrative review on...
This study evaluated the physicochemical characteristics and production of bioactive compounds Pereskia aculeata Mill. at different harvest times. Here, we performed a qualitative evaluation chemical profile by paper spray mass spectrometry (PSMS), phenolic acid flavonoid high-performance liquid chromatography (HPLC), antioxidant activity, total carotenoids, compounds, flavonoids, anthocyanins, color characteristics, soluble solids (TSS), (TS), pH, titratable acidity (TTA). The was not...
Resumo: Os óleos essenciais do gênero Callistemon possuem diversas propriedades bioativas.Condições ambientais e as alterações às quais plantas são expostas influenciam sobre o metabolismo a fisiologia das plantas.Assim, os produzidos por C. viminalis, biossintetizados em suas folhas, estão sujeitos edafoclimáticas.Analisou-se possíveis distinções entre perfis anatômicos, histoquímicos químicos de populações localizadas regiões com diferentes regimes hídricos fim caracterizar influência...
Black pepper (Piper nigrum L.) and pink (Schinus terebinthifolius Raddi) are two plant-based spices, which despite having a common popular name, have botanical family distinct centers of origin. Its fruits known worldwide in cuisine as condiments; addition, the extraction essential oil from these species is interesting pharmacological industrial perspective. In this sense, present study aimed to analyze chemical profile volatile organic compounds (VOC's) black pepper. The solid phase...
Em busca de um melhor rendimento esportivo e também na estética corporal, consumidores têm estimulado o crescimento do mercado dos suplementos alimentares, principalmente, os fonte proteica forma intacta hidrolisada. contrapartida, estudos demonstrado não conformidades nos requisitos regulamentados pela legislação vigente em relação à rotulagem destes produtos, fazendo das análises qualidade tema extrema relevância. Desta forma, este estudo teve por objetivo analisar proteicos tipo whey...
Maize (Zea mays) is a Poaceae of great global importance, which requires technological investment, such as the Bt events, for herbivores populational control can cause low productivity. This study aims to create parallel between metabolomics behavior maize variety and its isoline under influence provoked by two-spotted spider mite damage. Differences in identified ions concentration distribution were observed coming from monosaccharides, jasmonic acid methyl jasmonate ionizations,...
In the 1990s and 2000s, several countries underwent important significant changes in their universities. Likewise, Brazil, due to implementation of government programs, there was an expansion higher education made possible a greater access graduation. At beginning 2020, world threatened by COVID-19, restrictive measures were implemented private entities contain spread disease. this way, Brazilian educational institutions forced temporarily suspend in-person activities order promote social...
