Seeds of six species of genus Litsea Lam. (FamilyLauraceae), viz. L. angustifolia Hook. f., L. cubeba (Lour.) Pers. syn. L. citrata Blume, L. confertiflora (Meissn.) Kost., L. glutinosa (Lour.) C.B. Robins., L. laeta Benth. & Hook. f. and L. lanuginosa Nees were collected from 7-10 years old trees and investigated for their oil content and physicochemical properties. Fatty oil content of these ...

The biogeographic distribution of plant species is inherently associated with the plasticity of physiological adaptations to environmental variation. For semi-arid shrublands with a legacy of saline soils, characterization of soil water-tolerant shrub species is necessary for habitat restoration given future projection of increased drought magnitude and persistence in these ecosystems. Five dom...

There is an expanding interest in medicinal and aromatic plants as a natural alternative to synthetic drugs, especially antimicrobial agents due the growing problem of antibiotic resistance. In recent years, lot reports have been published on activity plant extracts. This study was used Lavandula angustifolia L., Mentha piperita Ribes nigrum L. materials. aims test extracts against oral bacteri...

Echinacea (Asteraceae), a North American genus of 11 recognized taxa (McGregor 1968), is of great economic and scientific interest. Three species, E. angustifolia DC. var. angustifolia, E. pallida (Nutt.) and E. purpurea (L.) Moench, show potential pharmacological activity (Bauer et al. 1988a; Bauer and Wagner 1991). Hydroalcoholic extracts of the roots of these three taxa stimulate phagocytosi...

OBJECTIVE To investigate the safety and efficacy of 2 extracts of echinacea for preventing upper respiratory tract infections. DESIGN Three-armed, randomized, double-blind, placebo-controlled trial. SETTING Four military institutions and 1 industrial plant. PARTICIPANTS Three hundred two volunteers without acute illness at time of enrollment. INTERVENTIONS Ethanolic extract from Echinac...

Somatic embryogenesis has been shown to be an efficient tool for studying processes based on cell growth and development. The fine regulation of the cell cycle is essential for proper embryo formation during the process of somatic embryogenesis. The aims of the present work were to identify and perform a structural and functional characterization of Mps1 and to analyze the effects of the inhibi...

INTRODUCTION Dysbiosis is associated with a number of gastrointestinal and systemic disorders. There is a need for selectively acting antimicrobial agents capable of inhibiting the growth of potentially pathogenic microorganisms, or those found to be out of balance, while not negatively impacting the bulk gastrointestinal tract microflora. OBJECTIVE The purpose of this in vitro study is to ex...
