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...

The aim of the study was comparing the chemical composition of the essential oils from five varieties of lavender (Lavandula angustifolia L.), and its biological activity against two pathogenic bacteria, Staphylococcus aureus and Pseudomonas aeruginosa. In the comparison we included the following varieties: 'Munstead', 'Munstead Strain', 'Lavender Lady', 'Ellegance Purple' and 'Blue River'. Sel...

(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...

Echinacea angustifolia and E. purpurea are commonly used in North America for their anti-bacterial effects. Flos Lonicerae, Radix Scutellaria and Fructus Forsythiae are traditional Chinese medicinal herbs commonly used for the treatment of complaints such as pneumonia, acute upper respiratory tract infection, and acute bronchitis. A reproducible, simple, and reliable rapid resolution liquid chr...

(Typhaceae): The effect of within and between year variations in salinity. Bull. Torrey Bot. Club 116: 364-370. 1989.-In a brackish wetland dominated by Typha angustifolia, we found similar aboveground and belowground produ...

A Croatian indigenous cultivar of lavandin, Lavandula x intermedia 'Budrovka' (Lamiaceae) was studied for the phenolic acids, flavonoids, anthocyanins, procyanidins and total tannins, as well as total polyphenols content, in the flower, inflorescence stalk and leaf ethanolic extracts. Antioxidant potentials on these plant part extracts were assessed by the DPPH free radical scavenging activity,...
