Trichomonas gallinae is a flagellated protozoan that parasitizes the upper digestive tract of various bird species and causes avian trichomonosis. The emergence of resistant strains to the standard treatment, based on nitroimidazoles, increases the need to find alternative therapies. In this study, 36 essential oils (EOs) from Lamiaceae and Asterac...
This work has demonstrated the ixodicidal and insect antifeedant effects of essential oils from 14 experimentally cultivated aromatic plants. The strong ixodicidal and antifeedant oils corresponded to Thymus zygis, Thymus vulgaris, Satureja montana, Oreganum virens, and Mentha suaveolens. The moderately active oils were from Lavandula angustifolia,...
Eight essential oils (EOs) from selected medicinal plants have been tested for their activity against Phytomonas davidi, a plant trypanosomal parasite. In the present research, the EOs have been tested on promastigote forms of P. davidi ATCC® 30287™ strain, along with their major components, both separately and in binary combinations, using the 3-(...
The aim of this study was to develop a chemically stable plant following a pre-domestication process and the valorization of its essential oil for the production of biopesticides. This study was conducted during four growing seasons to give a pre-domesticated population (SAMO-0). The resulting pre-domesticated population increased the hydrodistille...
The insecticidal and acaricidal effects of the essential oils (EO) from two populations of Geranium macrorrhizum L (ornamental variety Bevan, VB and wild population from Hungary, GH) have been studied against several insect pests of economic importance in agriculture (Spodoptera littoralis, Myzus persicae and Rhopalosiphum padi), and the hard tick...
Geranium macrorrhizum L. is a herbaceous perennial with underground stems (rhizomes) naturally found in the Balkan countries where it is known for its phytochemical properties. Despite its potential, there are no references to cultivation of this species to produce essential oil; to date only wild plants have been harvested. The purpose of this stu...
Maytenus ilicifolia Mart. ex Reissek (Celastraceae), conhecida popularmente por espinheira-santa, é nativa e cultivada, principalmente, no sul do Brasil. Suas folhas apresentam triterpenos e substâncias polifenólicas (flavonóides e taninos) relacionadas ao efeito antiulcerogênico. O objetivo do trabalho foi avaliar a produção de massa seca, altura,...
O trabalho teve o objetivo de avaliar o efeito de diferentes condições e períodos de armazenamento e diferentes períodos de embebição na germinação de sementes de erva-doce. As sementes foram armazenadas por 1, 3, 5, 7 e 9 meses em temperatura ambiente (22 ± 2ºC) e controlada (10ºC) e em seguida foram submetidas a cinco períodos de embebição (0, 12...
M. ilicifolia has antiulcerogenic and antigastric properties and a large pharmacological and cosmetic use not yet explored in a rational way. The development of plants submitted to various light and pruning managements was evaluated during a year. Two experiments were carried out, one in a shaded area under native species and another in a full sun...

Chamomile is an annual herbaceous species. Its flowers are used in popular medicine and as a vegetable flavour. It propagates for seeds. The objective of these trials was to evaluate the ideal temperature, packing time on the percentage and germination speed of chamomile. The first trial used seeds from a medicinal vegetable garden from Universidad...
In the present trial the effects of low temperatures on the surviving of chamomile seedlings originated from two different origins (local and imported seeds) was evaluated on the development, yield and concentration of quercetin. Forty to 10 cm high seedlings from the two origins were transferred to a germination chamber (BOD) during 24 hours and s...
Action of termic stress on the survival and yield of chamomile plantlets from imported and national seeds
In the present trial the effects of low temperatures on the surviving of chamomile seedlings originated from two different origins (local and imported seeds) was evaluated on the development, yield and concentration of quercetin. Forty to 10 cm...
RESUMO: Trabalhos relacionados com a qualidade de sementes de plantas medicinais ainda são incipientes, uma vez que a maioria era considerada planta daninha. Estudos básicos do desenvolvimento das culturas medicinais ainda são necessários, principalmente na área de recurso genético, devido a sua rica diversidade vegetal. Segundo autores de diversos...
