Background: Weedy non-native species have long been predicted to be more phenotypically plastic than native species. Question: Are weedy non-native species more plastic than natives? Organisms: Fourteen perennial plant species: Acer platanoides, Acer saccharum, Bromus inermis, Bromus latiglumis, Celastrus orbiculatus, Celastrus scandens, Elymus repens, Elymus trachycaulus, Plantago major, Plant...
background & aim: psyllium (plantago psyllium l.) is a native plant that grows widely in india and iran. different cases of using psyllium gum for its suitable rheological properties in a wide range of food products exist in nature. experimental: in this study, different fractions of psyllium gum were extracted by water and alkali treatments. rheological properties of these fractions were ...
We know very little about aging (senescence) in natural populations, and even less about plant aging. Demographic aging is identified by an increasing rate of mortality following reproductive maturity. In natural populations, quantifying aging is often confounded because changes in mortality may be influenced by both short- and long-term environmental fluctuations as well as age-dependent chang...
From the water-soluble part of an extract of Aragoa cundinamarcensis were isolated seven iridoid glucosides, namely aucubin, catalpol, rehmannioside D, globularin, gardoside methyl ester, epiloganin and mussaenoside. The main glycoside isolated, however, was a new caffeoyl phenylethanoid triglycoside, named aragoside, containing two beta-gluco- and one alpha-arabinopyranosyl moieties which cons...
The aim of my research was to screen secondary metabolites and antimicrobial activities of methanolic extracts of the leaves Vernonia amygdalina and Plantago lanceolata, and acetone extracts of the leaves Rosmarinus officinalis and Thymus schimperi against two bacteria (Staphylococcus aureus and Escherichia coli) and two fungi (Aspergillus niger and Fusarium oxysporum) using paper disc diffusio...
Antimicrobial Effects of Aqueous and Hydro-Alcoholic Plantago psyllium leaf extracts on the Experimental Infection Helicobacter pylori in a Rat Model
Plasiatine (1), isolated from the seeds of Plantago asiatica, is an unprecedented indole analogue linked to a phenylpropanoid moiety via a carbon bond that builds up a novel heteromeric construction with a C19N2 scaffold. Its structure was determined by spectroscopic data and computational evidence. Notably, experimental assay demonstrated that 1 significantly enhanced the activity of the nonre...
