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...
Toxicity of the essential oil of basil cultivars and hybrids and its repellent ...
Costa, Andréa Santos da; Arrigoni-BlanK, Maria Fátima de; Bacci, Leandro; Blank, Arie Fitzgerald; Alves, Péricles Barreto; Peixoto, Magna GalvãoEssential oils have emerged as an alternative to synthetic insecticides in the control of stored grain pests. The toxicity and repellency of the essential oils of four basil cultivars and three basil hybrids and the monoterpenes linalool, citral, and (E)-methyl cinnamate were evaluated in the stored grain pests Callosobruchus maculatus and Sitophillus zeamais. The essential oils of the cultivar Genovese and the...
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...
Content and chemical composition of the essential oil of Lippia gracilis Schaue...
Melo, Juliana Oliveira de; Blank, Arie Fitzgerald; Souza de Oliveira, Alisson Marcel; Andrade, Thiago Matos; Arrigoni-Blank, Maria de FátimaLippia gracilis, popularly known in Brazil as ‘alecrim-de-tabuleiro’, is used for many purposes, especially as antimicrobial and antiseptic. The drying process of aromatic and medicinal plants aims to minimize the loss of active principles and slow their deterioration, which may greatly influence the yield and chemical composition of some species. The objective of this study was to evaluate the effect of drying...
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...
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' ...
Acaricidal properties of vetiver essential oil from Chrysopogon zizanioides (Po...
Campos, Roseane Nunes de Santana; Lima, Cecília Beatriz Nascimento; Oliveira, Alexandre Passos; Araújo, Ana Paula Albano; Blank, Arie FitzgeraldTicks are arthropods widely distributed in tropical and subtropical regions, which can transmit infectious agents also responsible for zoonoses. Excessive use of conventional acaricides has resulted in the onset of drug resistance by these parasites, thus the need to use alternative methods for their control. This study evaluated the acaricidal activities of Chrysopogon zizanioides (vetiver) essential oils cont...
Influence of storage time and temperature on the chemical composition of the es...
Jesus, Alex Souza de; Blank, Arie Fitzgerald; Alves, Mercia Freitas; Arrigoni-Blank, Maria de Fátima; Lima, Rafaely Nascimento; Alves, Péricles BarretoHyptis pectinata, conhecida popularmente como Sambacaitá é uma erva medicinal nativa utilizada pela população local para o tratamento de enfermidades, cujas propriedades farmacológicas, antimicrobianas e medicinais foram relatadas em diversos estudos. O óleo essencial das folhas é rico em compostos terpênicos responsáveis pelas suas propriedades. Devido à existência de fatores que podem influenciar a composição...
Essential oils of Hyptis pectinata chemotypes: isolation, binary mixtures and a...
Feitosa-Alcantara, Rosana Barroso; Bacci, Leandro; Blank, Arie Fitzgerald; Alves, Péricles Barreto; Silva, Indira Morgana de AraújoLeaf-cutting ants are pests of great economic importance due to the damage they cause to agricultural and forest crops. The use of organosynthetic insecticides is the main form of control of these insects. In order to develop safer technology, the objective of this work was to evaluate the formicidal activity of the essential oils of two Hyptis pectinata genotypes (chemotypes) and their major compounds on the l...
Molecular and chemical characterization of vetiver, Chrysopogon zizanioides (L....
Celestino, Ricardo da Silva; Zucchi, Maria Imaculada; Pinheiro, José Baldin; Campos, Jaqueline Bueno de; Pereira, Alessandro AlvesDue to the economic interests in vetiver, Chrysopogon zizanioides (L.) Roberty, molecular and chemical studies are essential to generate information for its sustainable exploitation. The aim of this study was to undertake a molecular and chemical characterization of vetiver accessions of the active germplasm bank of the Universidade Federal de Sergipe. The molecular characteristics of the accessions were studie...
