摘要：

Six new flavonol 3-O-robinobiosides and 3-O-(2 ''-O-alpha-L-rhamnopyranosyl)-robinobiosides, sesuviosides A F, were isolated from the aerial portion of Sesuvium portulacastrum together with ecdysterone, adenosine, 2'-O-methyladenosine, and L-tryptophan. The structure elucidations were based on analyses of chemical and spectroscopic data including 1D and 2D-NMR. Sesuviosides A-F and their aglycones exhibited radical scavenging activity using DPPH and ORAC assays. (C) 2011 Elsevier Ltd. All rights reserved.
