Plantago major is a common plant that grows worldwide in temperate zones and is found in fields, lawns, and on the roadsides. Its leaves and seeds have been used in almost all parts of the world for centuries as a wound healer, analgesic, antioxidant, and antibiotic, as well as an immune system modulator, antiviral, antifungal, and anti-inflammatory agent. Baicalein and aucubin are the two most...
The seed of Plantago asiatica L. is one of the most popular folk herbal medicines used in China and other Asian countries. In this study, phenylethanoid glycosides and polysaccharides were isolated from the seed of P.asiatica L. by using phytochemical investigation methods. A screening model of immunological activity by using dendritic cells as target cells was established to investigate the ef...
A Mojave Desert shrub community was experimentally burned to understand changes in seed bank of desert annual plant species in response to wildfire. Seed mortality ranged from 55 to 80%, and fire caused significant losses of native and alien annual seeds. Schismus arabicus, Schismus barbatus, Bromus madritensis, Bromus tectorum, Erodium cicutarium and Plantago spp. made up >95% of the seed bank...
Genetic differentiation among plant populations and adaptation to local environmental conditions are well documented. However, few studies have examined the potential contribution of plant antagonists, such as insect herbivores and pathogens, to the pattern of local adaptation. Here, a reciprocal transplant experiment was set up at three sites across Europe using two common plant species, Holcu...
1. A glycoside of the aucubin type has been isolated in crystalline form from Plantago and Buddleia species, and has been shown to be identical with catalpol (Lunn, Edward & Edward, 1962). Catalpol has not been found in the free state before, but occurs as its p-hydroxybenzoyl ester, catalposide, in the genus Catalpa. 2. A second glycoside of this type has been obtained in crystalline form from...
