RESUMO
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 2D NMR spectroscopic analyses. The antioxidant potential of the new compound was assessed by the DPPH assay, and the RC50 value was found to be 1.4 x 10-4 mg/mL.
