This research aimed to develop statistical models predict basal area increment (BAI) for Araucaria angustifolia using Artificial Neural Networks (ANNs). Tree species were measured their biometric variables and identified at the level. The data subdivided into three groups: (1) intraspecific competition with A. angustifolia; (2) first group of that causes interspecific (3) second angustifolia. W...

Three zygotic developmental stages and two somatic Araucaria angustifolia cell lines with contrasting embryogenic potential were analyzed to identify the carbohydrate-mediated responses associated with embryo formation. Using a comparison between zygotic and somatic embryogenesis systems, the non-structural carbohydrate content, cell wall sugar composition and expression of genes involved in su...

The clinical efficacy of standardized essential oils (such as Lavender officinalis), in treating anxiety disorders strongly suggests that these natural products are an important candidate source for new anxiolytic drugs. A systematic review of essential oils, their bioactive constituents, and anxiolytic-like activity is conducted. The essential oil with the best profile is Lavendula angustifoli...

abstract the cowpea weevil, callosobruchus maculatus is the one of the most destructive pests of the dried seeds including cowpea, chickpea, lentil, mung bean and broad bean. in the last few decades, the use of environmental friendly insecticides, particularly plant-based compounds, has attracted attention of many researchers. the objective of the present work was to evaluate the fumigant toxic...

(Changes in polyamines associated with zygotic embryogenesis in the Brazilian pine, Araucaria angustifolia (Bert.) O. Ktze.). Changes in the polyamine content were analyzed in different embryo developmental stages and tissues during seed development in the conifer Araucaria angustifolia (Bert.) O. Ktze. Free polyamine contents varied according to the tissue and stage of embryo development, the ...

Alkamides are one of the most important constituents of lipophilic extracts of Echinacea angustifolia roots. These compounds play an important role in the versatile pharmacological actions of this plant. The present study aimed to compare the concentrations of isomeric dodeca-2E,4E,8Z,10E/Z-tetraenoic acid isobutylamides (DTAI) in brain and periepididymal fat tissues and blood plasma of rats. T...

In this paper we aimed to establish the content in polyphenolic compounds (flavones and polyphenolcarboxylic acids) in the soft extract of Elaeagnus angustifolia L. (oleaster) young branches, using high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS). The comparative analysis of the chromatograms obtained before and after hydrolysis showed a complex composition. We id...

objectives: leaves and flowers ofelaeagnus angustifolia contain phenolic and flavonoid compounds. these compounds have antioxidant properties that protect cells from oxidative damage. the aim of this study was to determine and analyze total phenolic and flavonoid content of leaves and flowers in two e. angustifolia variants using different solvents (ethanol and methanol). materials and methods:...
