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 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 ...
متن کاملNEW TAXA AND OTHER CONTRIBUTIONS TO THE TAXONOMY OF ALLIUM L. (ALLIACEAE) IN IRAN
The type plant of Allium akaka S.G. Gmelin ex Roem. & Schult. was probably collected in the mountains west of Bandar Anzali. Here plants fitting the original description are extant, and one was selected as epitype. This taxon in the strict sense is not conspecific with A. latifolium Jaub. & Spach, and is morphologically well separable from topo-typical plants of A. haemanthoides Boiss. & Reut. ...
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 کاملIntroduction to Botany of the Marquesas Islands: new taxa, combinations, and revisions
The Marquesas Islands (French Polynesia) are an isolated group of volcanic hot spot islands in the SE Pacific Ocean. These 12 islands range from 61.3 to 330 km2 in size, from 360 to 1250 m in elevation, and from 1.3 to 6.3 Ma in age. Steep and rugged, the Marquesas were, until recently, comparatively unexplored and under-collected botanically. The only existing flora for the region was that of ...
