The 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...
This study investigates the variations in the chemical profiles and biological activities (antioxidant and cytotoxic) of Eplingiella fruticosa from the state of Sergipe, an endemic species from the Northeast region of Brazil. The essential oils were extracted from six populations by hydrodistillation and analyzed by GC/MS-FID. Cluster analysis was performed with the data of the constituents of the essential oil...
This 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...
The 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...
Lippia 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...
Myrcia 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...
Tapirira guianensis Aubl. is a tree species important for wood, phytoterapy and restoration of degraded areas. The objective of this work was to characterize the structure of flowers, fruits and seeds. This study was carried out in the Agronomy Department of the Federal University of Sergipe (UFS), São Cristóvão, SE, Brazil. In the floral structure analysis, individuals were identified having male and female st...
The objective of this work was to evaluate the performance of basil cultivars and hybrids in two cropping seasons. The experiments were conducted in a randomized block design, with three replications. Twenty-four basil genotypes were tested (20 commercial cultivars and four hybrids), in the dry season (oct.-dec./2015) and in the rainy season (apr.-jun./2016). The evaluated variables were: plant height (cm plant...
Bromeliads are known worldwide for their ornamental potential. In Brazil, species of the genus Tillandsia occur in the Atlantic rainforest, Amazon rainforest, and rocky fields. This work aimed to evaluate the influence of nitrogen, phosphorus, and potassium fertilization on micropropagated seedlings of Tillandsia bulbosa, at the acclimatization stage, and their leaf anatomy. The experiment was carried out in a ...
The essential oils are secondary metabolites formed by several chemical compounds that confer to these substances great social and economic importance. This diversity of compounds is generally determined by the genetic constitution of the plant, although environmental factors may also influence the type, amount, and concentrations of the compounds present in the essential oil. The aim of this work was to analyz...
