Essential oils of Lippia gracilis and Lippia sidoides chemotypes and their majo...
Melo, Juliana Oliveira de; Blank, Arie Fitzgerald; Nunes, Rogéria de Souza; Alves, Péricles Barreto; Arrigoni-Blank, Maria de FátimaThe aim of this work was to evaluate the antifungal activity of essential oils (EOs) of Lippia gracilis and Lippia sidoides accessions, their major compounds and nanoemulsions. Nanoemulsions with 18% of EO or major compound were produced by spontaneous emulsification method. The EO of two L. gracilis accessions (LGRA-106 and LGRA-109) and two L. sidoides accessions (LSID-102 and LSID-104) were extracted by hydr...
Morpho-agronomic characterization of Varronia curassavica germplasm conservated...
Oliveira, Bruna Maria Santos de; Blank, Arie Fitzgerald; Nizio, Daniela Aparecida de Castro; Arrigoni-Blank, Maria Fátima; Bacci, LeandroVarronia curassavica Jacq. is a medicinal and aromatic plant native to Brazil. The essential oil of this species is valued by the pharmaceutical industry due to its bioactive substances containing anti-inflammatory properties. This study aimed to morpho-agronomically characterize 27 accessions of the collection of V. curassavica of the Active Germplasm Bank of Medicinal and Aromatic Plants of the Federal Univer...
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...
A comparative study of the antifungal activity of essential oils of Varronia cu...
Nizio, Daniela Aparecida de Castro; Blank, Arie Fitzgerald; Brito, Fabiany de Andrade; Gagliardi, Paulo Roberto; Alves, EduardoThis work aimed to compare the antifungal activity of the essential oil of Varronia curassavica obtained by hydrodistillation and microwave against the fungus Colletotrichum musae and verify the alterations caused by these extraction methods on the leaf surface. This study used four essential oil samples obtained by different methods, two by hydrodistillation [HD1 (1.0 L of water and 100 min.) and HD2 (2.0 L of...
Influence of storage temperatures and storage time of dry leaves on patchouli [...
Arrigoni-Blank, Maria de Fatima; Santos, Priscilla Santana; Blank, Arie Fitzgerald; Brito, Fabiany de Andrade; Andrade, Thiago MatosPatchouli [Pogostemon cablin (Blanco) Benth.] is a plant of the family Lamiaceae, widely used as an essential oil in the cosmetics and perfumery industry. This study aimed to evaluate the influence of storage time and temperature of dry leaves on the patchouli essential oil content and chemical composition. The experiment was performed in a completely randomized design in a 6x2x2 factorial scheme, testing stora...
Morphoagronomic characterization of Lantana camara L. germplasm
Nascimento, Luís Fernando de Andrade; Blank, Arie Fitzgerald; Sá Filho, José Carlos Freitas de; Pereira, Katily Luize GarciaThe medicinal and aromatic species Lantana camara is a bush that receives a lot of interest regarding ornamental use. However, due to its condition of invasive plant in natural environments, it suffers constant eradication attempts, which causes genetic erosion of the species. To work around this problem, a sample of the genetic variability of L. camara was saved in the Active Germplasm Bank of medicinal and ar...
In vitro antifungal activity of Myrcia ovata essential oils and their major com...
White, Larissa Alves Secundo; Blank, Arie Fitzgerald; Gagliardi, Paulo Roberto; Arrigoni-Blank, Maria de Fátima; Nizio, Daniela Aparecida de CastroMyrcia ovata, an endemic species to the Brazilian Atlantic Forest, presents antifungal properties. The phytopathogens Colletotrichum acutatum, Plenodomus destruens, and Thielaviopsis paradoxa are responsible for the diseases citrus postbloom fruit drop, sweet potato foot rot, and coconut stem bleeding, respectively. The antifungal activity of the essential oils of five M. ovata chemotypes (MYRO-159, nerolic aci...
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...
Distillation methods affect the chemical composition of Varronia curassavica Ja...
Nizio, Daniela Aparecida de Castro; Blank, Arie Fitzgerald; Sampaio, Taís Santos; Brito, Fabiany de Andrade; Andrade, Thiago MatosThe objective of this work was to evaluate the chemical composition of essential oil from Varronia curassavica Jacq. obtained by microwave (MI) and hydrodistillation (HD) extraction methods. The MI method tested three powers (500, 600, and 700W), three distillation times (20, 30, and 40 min.), and three water volumes (0, 25, and 50 mL per sample). The HD method tested three distillation times (100, 120, and 140...
