Plant-derived products can play an important role in pest management programs. Essential oils from Lavandula angustifolia (lavender) and Thymus vulgaris (thyme) and their main constituents, linalool and thymol, respectively, were evaluated for insecticidal activity and synergistic action in combination with insecticides against green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae). ...

Background: Osteoarthritis (OA) is the most common joint disorder without any curative treatment so, pharmacologic and nonpharmacologic modalities are used to improve pain and disability. Objectives: This is a study for evaluation of the efficacy and safety of Elaeagnus angustifolia and ginger extracts in patients with osteoarthritis of the knee. Patients and Methods: This randomized double-bli...

Although it is understood that the composition of riparian trees can affect stream function through leaf litter fall, the potential effects of genetic variation within species are less understood. Using a naturally hybridizing cottonwood system, we examined the hypothesis that genetic differences among two parental species (Populus fremontii and P. angustifolia) and two groups of their hybrids ...

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.

A Floresta Ombrófila Mista apresenta distribuição no sul do Brasil, desde o de São Paulo até a região central Rio Grande Sul. 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...
