Resistência de pragas a inseticidas, danos ao ambiente em função da poluição do solo e de recursos hídricos vem sendo observados pelo uso de inseticidas químicos no controle de pragas em grãos armazenados. Com o intuito de minimizar estes problemas, estão sendo estudadas alternativas como o uso de inseticidas botânicos. Este trabalho foi realizado com o objetivo de avaliar o efeito do óleo essencial de Tagetes patula L. sobre, Sitophilus zeamais Motschulsky, 1855 em milho sob condições de laboratório. O óleo essencial de T. patula foi obtido através de arraste a vapor com aparelho clevenger. A caracterização química dos compostos encontrados no óleo essencial de T. patula foi realizada através de cromatografia gasosa acoplado a espectrometria de massas,...

ABSTRACT Understanding the genetic structure and diversity of plants is fundamental to their conservation and permits their sustainable use by local communities. The genus Maytenus (Celastraceae) is composed of plants possessing pharmacological and antioxidant properties. However, the genetic and economic properties of the species M. dasyclada, a typical species of Araucaria forests in Brazil and Uruguay, have been little studied. In this work, the genetic structure and diversity of natural populations of M. dasyclada located in unprotected and preserved forest remnants were investigated using RAPD and isozymes markers. The results demonstrated that in areas of preservation, populations of M. dasyclada possess a relatively high degree of polymorphism and...

The use of compressed carbon towards extracting semi-volatile compounds present in maté leaves (Ilex paraguariensis St. Hil.) is due to the growing interest in mate constituents to develop new products in the cosmetic, pharmaceutical and food industries. The objective of this work was to assess the chemical distribution of semi-volatile compounds in 20 native populations of maté collected all over Brazil. The extracts of bulk samples (30 plants) of each population were obtained by the high-pressure carbon dioxide extraction technique, and analyzed by GC/MSD. The quantification of compounds (caffeine, theobromine, phytol, squalene, vitamin E, eicosane, pentatriacontane, and stigmasterol) showed significant variations within the different populations and...

Evaluation of Origanum vulgare essential oil as antimicrobial agent in sausage
Provedor de dados: 58
Autores: Busatta,Cassiano; Mossi,Altemir José; Rodrigues,Maria Regina Alves; Cansian,Rogério Luis; Oliveira,José Vladimir de.
This work reports antimicrobial activity of oregano (Origanum vulgare) essential oil against several bacteria in sausage. The in vitro minimum inhibitory concentration (MIC) was determined for 9 selected aerobic heterotrofic bacteria. The antimicrobial activity of distinct concentrations of the essential oil on the basis of the highest MIC found was tested in a food system comprised of fresh sausage. Batch food samples were also inoculated with Escherichia coli with a fixed concentration and the time course of the product was evaluated with respect to the action of the different concentrations of essential oil. Sensory analysis were conducted, and results showed that the addition of oregano essential oil to sausage may be a promising route as...
