New Anti-HBV C-Boivinopyranosyl Flavones from Alternanthera philoxeroides.
C-boivinopyranosyl flavones have rarely been isolated from nature. In the search for anti-HBV (hepatitis b virus) constituents of Alternanthera philoxeroides, two new compounds, luteolin-6-C-β-D-boivinopyranosyl-3'-O-β-D-glucopyranoside (1) and chrysoeriol-6-C-β-D-boivinopyranosyl-4'-O-β-D-glucopyranoside (2), along with three known C-boivinopyranosyl flavones (compounds 3-5) were isolated. The...
متن کاملSalinity Effects on Water Potential Components and Bulk Elastic Modulus of Alternanthera philoxeroides (Mart.) Griseb.
Pressure volume curves for Alternanthera philoxeroides (Mart.) Griseb. (alligator weed) grown in 0 to 400 millimolar NaCl were used to determine water potential (Psi), osmotic potential (psi(s)), turgor potential (psi(p)) and the bulk elastic modulus (epsilon) of shoots at different tissue water contents. Values of psi(s) decreased with increasing salinity and tissue Psi was always lower than r...
متن کاملMolecular phenotypes associated with anomalous stamen development in Alternanthera philoxeroides
Alternanthera philoxeroides is a perennial amphibious weed native to South America but has now spread to diverse parts of the world. A. philoxeroides reproduces both sexually and asexually in its native range, but propagates solely through vegetative means in its introduced range. Traits associated with sexual reproduction become degraded for sexual dysfunction, with flowers possessing either p...
متن کاملAn innovative method for the biological control of Alternanthera philoxeroides
Biological invasion has become a serious global environmental problems and been considered as an important component of global change. Invasions by alien species can have an impact at several levels of ecological complexity from genes to ecosystems. Invasive alien species had seriously threated the biodiversity and natural ecosystems in China, and caused economic losses by more than US$7 billio...
متن کاملThe Invasive Wetland Plant Alternanthera philoxeroides Shows a Higher Tolerance to Waterlogging than Its Native Congener Alternanthera sessilis
Plant invasion is one of the major threats to natural ecosystems. Phenotypic plasticity is considered to be important for promoting plant invasiveness. High tolerance of stress can also increase survival of invasive plants in adverse habitats. Limited growth and conservation of carbohydrate are considered to increase tolerance of flooding in plants. However, few studies have examined whether in...
