Myocardial infarction (MI) is a common presentation of the ischemic heart disease. Lavandula angustifolia is a herbaceous plant with antioxidative effects.This study was designed to investigate the cardioprotective effects of lavandula angustifolia essential oil against isoproterenol-induced MI in rats.The dried sample was subjected to hydrodistillation by using a Clevenger and the oils were dr...

The feeding preferences of the Formosan subterranean termite, Coptotermes formosanus Shiraki, were tested in three separate experiments on 28 different wood species. Experiment 1 was a multiple-choice test designed to test relative preferences among 24 wood species commercially available in New Orleans, LA. Experiment 2 was a similar study designed to test relative preferences among 21 wood spe...

Nine bisindole alkaloids, comprising four belonging to the macroline-sarpagine group, and five belonging to the macroline-pleiocarpamine group, were isolated from the stem-bark extracts of Alstonia angustifolia (Apocynacea). Their structures were established using NMR and MS analyses.

O estudo teve por objetivo apresentar uma composição aves diurnas e noturnas em um mosaico floresta ombrófila mista junção talhões plantios com Araucaria angustifolia Pinus elliotti na Nacional Francisco Paula, estado Sul, Brasil. Foram realizadas amostragem quatro difer...

Two major emergent macrophytes, Phragmites australis and Typha angustifolia, show a clear zonation with respect to water depth, i.e., P. occupies shallower than T. angustifolia. However, the reasons for this interspecific difference is unclear. Therefore, study focused on features that enable angustifolia survive at greater depths australis. In both outdoor greenhouse experiments, did not deepe...

Essential oil components were extracted from Lavandula angustifolia (Lavender) flowers using pressurized fluid extraction (PFE). A Box-Behnken design was used to optimize the effective extraction variables. The chemical composition of extracted samples was analyzed by gas chromatograph-flame ionization detector column. For achieving maximum % extraction yield the temperature, pressure, and dyna...

In vascular plants the shoot apical meristem consists of three tissue layers, L1, L2 and the L3, that are kept separate during organ formation and give rise to the epidermis (L1) and the subepidermal tissues (L2, L3). For proper organ development these different tissue layers must interact with each other, though their relative contributions are a matter of debate. Here we use ANGUSTIFOLIA (AN)...

The use of bioactive tanniniferous plants seems a promising alternative to control infections parasitic nematodes of the gastro intestinal tract in small ruminants. Both in vitro and in vivo studies, have confirmed the anthelmintic properties of several forage legumes, or tropical and browse plants. The aim of the present study was to evaluate the in vitro anthelmintic (AH) effect of 3 Tunisian...

(Leaf anatomy of Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae)). Immature and mature leaves of juvenile and adult plants of Araucaria angustifolia (Araucariaceae) were observed with the objective of updating the morphoanatomical data of the leaves of this species, which were restricted to basic descriptions in previous studies. The observations, made in optical allowed to establish an...
