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...
متن کاملGermination behaviour of seeds from herbicide treated plants of Chenopodium album L.
The carry-over effect of sub-lethal herbicides was investigated on the germination of seeds collected from surviving Chenopodium album plants, which had received 1/8, 1/8 twice, 1/8 three times, 1/4, 1/2, 1/1 doses of either pre-emergence ioxynil or post-emergence bentazone in a previous onion (Allium cepa) crop. Seeds were also collected from surviving C. album plants, which had received 1/4, ...
متن کاملChanges in phenolic composition and antioxidant activity during germination of quinoa seeds (Chenopodium quinoa Willd.)
Quinoa seed (Chenopodium quinoa Willd.) has obtained great interest in recent years due to its high nutritional value and its content of natural antioxidants and other phytochemicals with positive biological activity in humans. Their ability as health promoters depends strictly on the processing conditions to which the seeds are submitted. In this work, quinoa seeds were subjected to germinatio...
متن کاملAllopolyploid 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...
متن کاملPhenotypic 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 ...
