Various species of common box (Buxus) are cultivated in the Arboretum of the Slovak Academy of Sciences in Mlyňany under the same soil and climatic conditions; consequently, the examination of alkaloids produced by those plants is of chemotaxonomical importance. From this locality we investigated so far alkaloids from Buxus sempervirens L.[l,2], B. microphylla SIEB, et ZUCC. var. sinica REHD. e...

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...

To identify plants with bioactive potential for skin care, methanol extracts of 56 plant parts from 47 medical and edible plants cultivated in Okinawa were tested for their proliferative effects on NB1RGB skin fibroblast cells. Extracts from six plants, Bischofia javanica, Colocasia esculenta, Melaleuca alternifolia, Piper angustifolia, Jasminum sambac, and Curcuma longa, showed higher NB1RGB c...

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...

(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...
