Understanding the distribution of hundreds thousands plant metabolites across kingdom presents a challenge. To address this, we curated publicly available LC-MS/MS data from 19,075 extracts and developed plantMASST reference database encompassing 246 botanical families, 1,469 genera, 2,793 species. This taxonomically focused facilitates exploration plant-derived molecules using tandem mass spectrometry (MS/MS) spectra. tool will aid in drug discovery, biosynthesis, (chemo)taxonomy,...
O presente estudo tem como objetivo revisar a literatura respeito dos impactos do uso de simuladores ferramenta para aprimoramento técnico residentes cirurgia geral. Este trata-se uma revisão integrativa da literatura, cuja principal característica é possibilidade reunir e sintetizar achados pesquisas anteriores sobre o tema interesse, proporcionando visão abrangente aprofundada. Os estudos foram identificados através estratégia busca abrangente. A foi realizada nas seguintes bases dados:...
Peperomia pellucida is a species known in the Amazon as "erva-de-jabuti" that has been used several therapeutic applications based on folk medicine. Herein, we describe classes, subclasses, and main compounds of leaves, stems, roots from P. by ultra-high performance liquid chromatography coupled to high-resolution mass spectrometry associated with molecular networks, mirror plot GNPS library, machine learning. These data show were annotated for first time genus, such...
L. (Cucurbitaceae) is a plant known in Brazil as "melão de São Caetano", which has been related to many therapeutic applications folk medicine. Herein, we describe antibacterial activities and metabolites for an extract fractions obtained from the leaves of that species. An ethanolic its three were used perform vitro assays. In addition, liquid chromatography coupled mass spectrometry molecular networking approach metabolite annotation process. Overall, 25 compounds annotated
Chamaecrista diphylla (L.) Greene (Fabaceae/Caesalpiniaceae) is a herbaceous plant that widely distributed throughout the Americas. Plants from this genus have been used in traditional medicine as laxative, to heal wounds, and treat ulcers, snake scorpion bites. In present study, we investigated chemical composition of leaves through mass spectrometry molecular network approach. The oxygen radical absorbance capacity (ORAC) for ethanolic extract, enriched fractions isolated compounds was...
Stryphnodendron pulcherrimum is a plant found in the Brazilian Amazon and contains high content of catechin/(epi)catechin (flavan-3-ol) derivatives. The polymerization this kind flavan-3-ol generates condensed tannins, often associated to plant-based diets gut microbiota. Thus, discovery tannins from plants valuable approach once it enhances their availability natural sources. Herein, we described tetrameric tannin (Molecular Mass 1,170 a.m.u.) tentatively identified for first time barks S....
Swietenia macrophylla King is a plant commonly known as Brazilian mahogany. The wood from its stem highly prized for exceptional quality, while leaves are valued their high content of phragmalin-type limonoids, subclass compounds significant biological activities, including antimalarial, antitumor, antiviral, and anti-inflammatory properties. In this context, twelve isolated limonoids S. were employed standards in mass spectrometry-based molecular networking to unveil new potential...
Abstract Introduction This study describes the molecular profile and potential antiviral activity of extracts from Phyllanthus brasiliensis , a plant widely found in Brazilian Amazon. The research aims to shed light on use this species as natural agent. Methods were analysed using liquid chromatography–mass spectrometry (LC–MS) system, potent analytical technique discover drug candidates. In meantime, vitro assays performed against Mayaro, Oropouche, Chikungunya, Zika viruses. addition,...
Deguelia nitidula (Benth.) A.M.G.Azevedo & R.A.Camargo (Fabaceae) is an herbaceous plant distributed in the Brazilian Amazon, and it called “raiz do sol” (sun roots). On Marajó Island, quilombola communities use its prepared roots to treat skin diseases commonly caused by fungi, viruses, bacteria. Thus, this study, extract, fractions from D. were used perform vitro cytotoxic antibacterial assays against Staphylococcus aureus strains. Thereafter, liquid chromatography–mass spectrometry...
O mel é rico em monossacarídeos de glicose e frutose vem sendo cada vez mais utilizado como alimento, medicamento conservantes; tornando-se necessário definir padrões qualidade para este produto. presente trabalho investigou o perfil microbiológico físico-químico méis dos municípios Cachoeira do Ararí, Salvaterra - PA, afim padronizar os dados através testes componentes principais agrupamentos. Foram analisadas dez amostras, obtendo-se valores médios cinzas (0,38%), acidez livre (28,77...
Based on chemotaxonomy, the specie Chamaecrista diphylla (L.) Greene became object of study this work, since it is part same genus C. nictitans, where there are proanthocyanidins, which act against Herpes Simplex Virus. Thus, work aimed to determine compounds phenol content and antioxidant potential extracts fractions leaves diphylla. Quantitative analysis showed ethyl acetate fraction (F-AcOEt) ethanolic extract (EE) highest levels phenolic compounds, flavonoids condensed tannins. Referent...
Neste trabalho foi realizado um estudo a respeito das contribuições que o Estágio Curricular Supervisionado (ECS) oferece à formação inicial docente, com ênfase no professor de Química, acordo experiências adquiridas por graduandos do curso Ciências Naturais Habilitação em Química da Universidade Estado Pará (UEPA). A pesquisa desenvolvida durante as disciplinas - Vivências Ensino Médio I e II, 16 campus Salvaterra-PA. interpretação dos dados coletados realizada aporte na “Análise Contéudo”....
Abstract Introduction : Plants of the genus Phyllanthus ( Euphorbiaceae ), “stone breaker” has long been used in folk medicine to treat hepatitis B, an important viral disease. In this regard some species were tested against viruses as Herpes simplex virus type 1 (HSV-1), COVID and Hepatitis C (HCV), showing expressive inhibition them, attracting attention its chemical constituents. Although P. brasiliensis no traditional use antiviral plant, these findings urge us consider whether , plant...
