Chenoalbuside: an antioxidant phenolic glycoside from the seeds of Chenopodium album L. (Chenopodiaceae)

In addition to three known phytoecdysteroids, a new phenolic glycoside (named, chenoalbuside) was isolated from the methanol extract of the seeds of Chenopodium album. While the structures of all phytoecdysteroids were elucidated by direct comparison of their spectroscopic data with published data, the structure of chenoalbuside was determined unequivocally by a combination of UV, MS and 1D and...

Morphophysiological traits and atrazine sensitivity in Chenopodium album L.

BACKGROUND A Chenopodium album L. biotype surviving in atrazine-treated Serbian corn fields (VC) was compared against atrazine-susceptible (S) and atrazine-resistant (R) standards. RESULTS Atrazine (2 kg ha(-1)) killed S and VC shoot biomass 15 days after treatment (DAT), but R was only suppressed by 42% and survived 8 kg ha(-1). Atrazine at 2 kg ha(-1) only inhibited VC height by 60% as agai...

Phenotypic plasticity to light competition and herbivory in Chenopodium album (Chenopodiaceae).

Competition and herbivory are ubiquitous environmental challenges that affect most plants. We examined the influence of phenotypic responses to either competition or herbivory on the subsequent response of the plants to the other factor. The stem-elongation response of Chenopodium album to light competition attenuated its resistance to caterpillar herbivory in terms of herbivore mortality, but ...

Expansion of Chenopodium Album Leaf Disks as Affected by Coumarin.

Although leaf expansion is obviously a fundamental process in the development of plants, its physiological mechanism is little understood, and has been but sparingly investigated. It is known that auxins affect the elongation of the leaf veins (1) but do not seem to influence the expansion of the laminar leaf tissues. BONNER et al. (3) observed an increase in expansion of radish leaf disks floa...

Allopolyploid Origin of Chenopodium album s. str. (Chenopodiaceae): A Molecular and Cytogenetic Insight

Reticulate evolution is characterized by occasional hybridization between two species, creating a network of closely related taxa below and at the species level. In the present research, we aimed to verify the hypothesis of the allopolyploid origin of hexaploid C. album s. str., identify its putative parents and estimate the frequency of allopolyploidization events. We sampled 122 individuals o...
