Establishment of methodology for drying leaves and storage of essential oil of ...
Alves, Mercia Freitas; Blank, Arie Fitzgerald; Arrigoni-Blank, Maria de Fátima; Fontes, Saymo Santos; Jesus, Hugo César Ramos deO objetivo deste estudo foi avaliar a influência da secagem de folhas e de armazenamento de óleo na composição de conteúdo e química do óleo essencial de manjericão (Ocimum basilicum L.) cultivar Maria Bonita. No primeiro ensaio, o efeito do tempo de secagem de folhas a uma temperatura de 40 °C. No segundo ensaio, o efeito do tempo de armazenamento avaliado (0, 15, 30, 60, 90, 120, 150, 210, 240 e 270 dias) em ...
Composição química do óleo essencial de sete genótipos de Lippia gracilis e rea...
Jesus, Hugo César Ramos deCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; This work attempts to make a study of the chemical composition of the essential oil from leaves of seven Lippia gracilis genotypes. In addition, we investigated the effect of water stress on the chemical composition of the essential oil (EO) of the species. A total of 32 volatile compounds were identified with predominance of phenolic monoterpenes: ca...
Cytotoxic effects of essential oils from three Lippia gracilis Schauer genotype...
Melo, Juliana Oliveira de; Saltoratto, Ana Lucia Fachin; Rizo, Walace Fraga; Jesus, Hugo César Ramos de; Arrigoni-Blank, Maria de FátimaThis study aimed to evaluate the chemical composition of the essential oils from three genotypes of Lippia gracilis Schauer (Verbenaceae) and investigate the cytotoxic activities of these oils. Essential oils were extracted from the leaves using a Clevenger-type apparatus, and chemical analysis was performed using a gas chromatograph coupled to a mass spectrometer and flame ionization detector. 3T3, MRC5, B16, ...
Water deficit and seasonality study on essential oil constituents of Lippia gra...
Cruz, Elizangela Mércia de Oliveira; Pinto, Jéssika Andreza Oliveira; Fontes, Saymo Santos; Arrigoni-Blank, Maria de Fátima; Bacci, LeandroThe aim of this study was to analyze the chemical composition of the essential oil from leaves of Lippia gracilis genotypes, in the dry and rainy seasons, and with and without irrigation. The extraction of essential oil was realized by hydrodistillation in a Clevenger apparatus. The chemical composition analysis was performed using a GC-MS/FID. The leaves of the L. gracilis genotypes provide essential oil with ...
Influência do armazenamento de folhas secas no óleo essencial de patchouli (Pog...
Sant'ana, Trícia Cavalcanti Pergentino de; Blank, Arie Fitzgerald; Vieira, Sylvia Dantas; Arrigoni-Blank, Maria de Fátima; Jesus, Hugo César Ramos deThe aim of this work was to evaluate the influence of five storage times of dry leaves of two patchouli genotypes on its essential oil content and chemical composition. Harvest was realized four months after planting. Storage influenced essential oil content of genotype POG-002. Patchoulol was the majority compound. Storage of dry leaves increased significatively the content of the compounds α-bulnesene and ger...
Composition and evaluation of the lethality of Lippia gracilis essential oil to...
Teles, Tatiana Vieira; Bonfim, Rangel Rodrigues; Alves, Péricles Barreto; Blank, Arie Fitzgerald; Jesus, Hugo César Ramos deLippia gracilis essential oil (LGEO) was evaluated for its molluscicidal activity against Biomphalaria glabrata and toxicity to brine shrimps (Artemia salina). L. gracilis was collected from the city Tomar do Gerú- Sergipe, Brazil. The LGEO were characterized by gas chromatography-mass spectrometry (GC/MS). The values of LC10, LC50 and LC90 were respectively 36.9, 62.2 and 82.8 ppm for B. glabrata and 19.6, 23....
