Sena, Jéssica da Silva; Rodrigues, Selma Alves; Sakumoto, Karina; Inumaro, Rodrigo Sadao; González-Maldonado, Pamela; Mendez-Scolari, EmilioThe chemical composition of extracts (CEs) and essential oils (EOs) from Tetradenia riparia leaves, flower buds, and stems was analyzed. Antiproliferative activity against tumor cell lines, NO production inhibition, and antioxidant and antiviral activities were assessed. The CEs contained flavonoids, phenolic acids, coumarins, and saturated fatty acids. The EOs included monoterpenes, oxygenated sesquiterpenes, ...
Chemical profile and bioactivities of industrial wastes from Chenopodium quinoa...
Casalvara, Rhaira Fernanda Ayoub; Santos, Everton da Silva; Mattos, Jose Vinicius; Pimentel, Tatiana Colombo; Calhelha, Ricardo C.; Pires, Tânia C.S.P.This study aimed to investigate the effect of extraction methods and solvents (Soxhlet and supercritical fluid extraction, SFE) on the chemical profile (gas chromatography [GC]/mass spectrometry and GC/flame ionization detection) and antimicrobial, antioxidant, antitumor, and anti-inflammatory activities of quinoa Piabiru (QP) husk crude extracts. Soxhlet was applied using 100% water (QPSH2O), and ethanolic sol...
Bioactives of the essential oil from the leaves of Eugenia pyriformis Cambess (...
Medeiros, Jaqueline Pavelegini de; Rodrigues, Selma Alves; Sakumoto, Karina; Ruiz, Suelen Pereira; Faria, Maria Graciela Iecher; Gonçalves, José EduardoLung cancer is the most commonly diagnosed and the main cause of cancer death, usually related to cigarette smoking. Furthermore, the microbiota of people exposed to cigarette smoke can be modified, making it difficult to eliminate opportunistic microorganisms. The leaves of Eugenia pyriformis are a by-product of fruit production and, to date, there have been no studies addressing the antiproliferative, anti-in...

Cellular antioxidant, anti-inflammatory, and antiproliferative activities from ...
Silva, Gabriela Catuzo Canonico; Machado, Mariane de Almeida; Sakumoto, Karina; Inumaro, Rodrigo Sadao; Gonçalves, José Eduardo; Mandim, FilipaGallesia integrifolia, a notable species in the Atlantic Forest, has been traditionally employed in folk medicine for treating rheumatism, asthma, and worms. This study investigated the cellular antioxidant, antiproliferative, and anti-inflammatory activities of the essential oils (EOs) and crude extracts (CEs) from G. integrifolia flowers, fruits, and leaves. The chemical identification of EOs was performed by...
Supercritical fluid-assisted extraction of hop cone residue from craft breweries
Inumaro, Rodrigo Sadao; Casalvara, Rhaira Fernanda Ayoub; Corrêa, Rúbia C.G.; Barros, Lillian; Pereira, Carla; Calhelha, Ricardo C.; Heleno, Sandrina A.This study aimed to use supercritical fluid-assisted extraction in hop cone residue from craft breweries and define the best extraction parameters. Yield, compounds extracted, in vitro chemical and cell-based antioxidant ac-tivities, and antimicrobial and cytotoxic potentials were evaluated. The variables studied were temperature (40-60 degrees C), pressure (10-20 MPa), and ethanol percentage as co-solvent (5-1...
Ora-pro-nobis - chemical characterization and sourcing of crude extract through...
Carnevalli, Denise Bertin; Ramos, Cintia Neves; Mardigan, Laura Paulino; Meurer, Eduardo Cesar; Cardozo Filho, Lucio; Gomes, Rúbia Correa CarvalhoOra-pro-nobis has its center of origin in tropical America. It is found in Brazil, from the Northeast to Rio Grande do Sul. The plant belongs to the Cactaceae family, Pereskia genus. Its leaves and fruits contain bioactive compounds that may have expectorant properties and can be used to alleviate inflammatory processes in traditional medicine. Despite its richness, the plant is still little used by the general...

An analytical method for the quantitative determination of iron ion chelating c...
Santos, Éverton da Silva; Teixeira, Leticia de Melo; Castro, Juliana Cristina; Mardigan, Laura Paulino; Santos, José Rivaldo dosIron is a fundamental microelement for human life; however, deficiencies or excesses of these metal ions can cause severe complications and mortality. Chelators are compounds that bind and inhibit iron. Ultraviolet-visible (UV-vis) spectrophotometric methods are key analytical tools in the identification of chemical entities, with the benefits of having good precision and accuracy, and the equipment being easil...
Effect of sucrose on the fatty acid metabolism of adventitious root cultures in...
Follador, Bruna Gabrieli; Santos, Éverton da Silva; Gonçalves, José Eduardo; Gonçalves, Regina Aparecida Correia; Oliveira, Arildo José Braz deIn this study, the effect of sucrose on the neutral lipid profile of adventitious root cultures of Stevia rebaudiana was evaluated. The cultures were obtained employing a roller bottle system. In this system, Schott-type flasks were used, which contained Murashige and Skoog liquid medium at 33.3% strength (MS/3) supplemented with 30, 60, and 80 g L-1 of sucrose, respectively, and 10.7 mM 1-naphthaleneacetic aci...
