Antifungal activity of essential oils of Myrcia ovata chemotypes and their majo...
Sampaio, Taís Santos; Blank, Arie Fitzgerald; Gagliardi, Paulo Roberto; Wisniewski Jr, Alberto; Arrigoni-Blank, Maria de FátimaThis work evaluated the antifungal activity of essential oils of Myrcia ovata chemotypes (MYRO-175, MYRO-156, MYRO-154, MYRO-165, and MYRO-015) and their major compounds (linalool, geraniol, citral, and (E)-nerolidol) on the phytopathogenic fungi Fusarium pallidoroseum (which causes melon postharvest rot) and Colletotrichum musae (which causes anthracnose in banana). The essential oils were obtained by hydrodis...
Fertilization and cropping systems: performance and oil content of basil varieties
Silva, Adeláide Siqueira; Oliveira, Roberta Camargos; Luz, José Magno Queiroz; Silva, Sérgio Macedo; Blank, Arie Fitzgerald; Alves, Mércia FreitasSweet basil (Ocimum basilicum L.) is an aromatic and medicinal crop that produces metabolites rich in chemical constituents for various purposes. The composition of the essential oil is variable due to external factors during production, such as fertilization and the environment, and the oil concentration may vary even among the genotypes of a species. For sweet basil mores studies are needed to clarify underst...
Inheritance study of yield components and essential oil constituents in linool ...
Alves, Mércia Freitas; Blank, Arie Fitzgerald; Nizio, Daniela Aparecida de Castro; Blank, Maria de Fátima Arrigoni-; Alves, Péricles BarretoThe aim of this study was to conduct an inheritance study for the agronomic and chemical characteristics of basil (Ocimum basilicum L.) hybrid 'Genovese' x 'Maria Bonita'. F1 seeds were obtained from a cross of P1 (Genovese) x P2 (Maria Bonita). F2 seeds were obtained from selfing five F1 plants. In this experiment, a randomized block design with three replications was used. Each replication consisted of four t...
Content and chemical composition of the essential oil of Myrcia lundiana Kiaers...
Alves, Mércia Freitas; Blank, Arie Fitzgerald; Andrade, Thiago Matos; Nizio, Daniela Aparecida de Castro; Sampaio, Taís SantosThis study aimed to evaluate the effect of the leaves drying time on the content and chemical composition of the essential oil of M. lundiana. Treatments consisted of drying times of 0, 1, 2, 3, 4, 5, 6, 8, and 10 days, at 40o C, in a forced-air-circulation oven. Essential oils were obtained by hydrodistillation using the Clevenger apparatus, and chemical composition analysis was performed by GC-MS/FID. The dry...
Essential oils of Myrcia lundiana Kiaersk and their major compounds show differ...
Alves, Mércia Freitas; Blank, Arie Fitzgerald; Gagliardi, Paulo Roberto; Arrigoni-Blank, Maria de Fátima; Nizio, Daniela Aparecida de CastroThe present study evaluated the antifungal activity of the essential oils of chemotypes of Myrcia lundiana and their major compounds on the fungi Fusarium pallidoroseum, Fusarium solani, and Colletotrichum musae. The essential oils were obtained by hydrodistillation and analyzed by GCMS/FID. For the evaluation of the antifungal activity, the essential oils and the major compounds were tested at the concentratio...
Phenotypic and genotypic characterization of basil hybrids and cultivars
Santana, Alea Dayane Dantas de; Blank, Arie Fitzgerald; Arrigoni-Blank, Maria de Fátima; Andrade, Thiago Matos; Alves, Mércia FreitasThis study aimed to evaluate the phenotypic and genotypic performance of basil (Ocimum basilicum L.) hybrids and cultivars, grown in four crop years, in the municipality of São Cristóvão, state of Sergipe. The following variables were evaluated: dry weight of aerial part; essential oil content and yield; and the contents of linalool, 1,8-cineol, neral, geranial, and methyl cinnamate. Five hybrids ('Sweet Dani' ...
Secagem, armazenamento e controle genético de caracteres agronômicos e químicos...
Alves, Mércia FreitasConselho Nacional de Desenvolvimento Científico e Tecnológico; The aim of this work was to evaluate the influence of drying of leaves, the storage time of the essential oil and to study the inheritance of agronomic and chemical characters of basil (Ocimum basilicum L.). Three assays were carried out, where the effect of drying time of leaves, the influence of storage in different environments and the study of i...
Estudo fitoquímico, genético e atividade antifúngica do óleo essencial de Myrci...
Alves, Mércia FreitasFundação de Apoio a Pesquisa e à Inovação Tecnológica do Estado de Sergipe - FAPITEC/SE; The objectives of this study were to characterize chemically the essential oils, to evaluate the genetic diversity and the antifungal activity of Myrcia lundiana plants collected in Serra de Itabaiana National Park, Areia Branca Municipality / SE. The essential oils of 23 plants of M. lundiana were obtained by hydrodistilla...
The Impact of Hybridization on the Volatile and Sensorial Profile of Ocimum bas...
Costa, Andrea Santos da; Arrigoni-Blank, Maria de Fátima; Silva, Maria Aparecida Azevedo Pereira da; Alves, Mércia FreitasThe aim of the present study was to investigate the volatile and sensorial profile of basil (Ocimum basilicum L.) by quantitative descriptive analysis (QDA) of the essential oil of three hybrids (“Cinnamon” × “Maria Bonita,” “Sweet Dani” × “Cinnamon,” and “Sweet Dani” × “Maria Bonita”). Twelve descriptive terms were developed by a selected panel that also generated the definition of each term and the reference ...
Establishment of methodology for drying leaves and storage of essential oil of ...
Alves, Mércia Freitas; Blank, Arie Fitzgerald; Arrigoni-Blank, Maria Fátima; Fontes, Saymo Santos; de Jesus, Hugo César Ramos; Alves, Péricles BarretoThe aim of this study was to evaluate the influence of leaf drying and oil storage on the content and chemical composition of the essential oil of linalool type basil (Ocimum basilicum L.) cultivar Maria Bonita. In the first trial, the effect of the drying time of leaves a temperature of 40°C. In the second trial, the effect of storage time evaluated (0, 15, 30, 60, 90, 120, 150, 210, 240 and 270 days) at two t...
