TL;DR: Two lignan sulfates, a stilbene derivative and a phenol sulfate, together with 10 known compounds, were isolated from an aqueous extract of the root of Polygonum cuspidatum showing no inhibition of lipid peroxidation and no cytotoxic and DNA cleavage activities.

TL;DR: In this article, 10 naturally occurring stilbene glycoside sulfates (1-10) were isolated from an aqueous extract of the root of Polygonum cuspidatum.

TL;DR: The 70 % EtOH extract of Polygonum cuspidatum showed inhibitory action against HIV-1-induced syncytium formation at non-cytotoxic concentrations in vitro with a 50 % effective concentration (EC(50)) of 13.94 +/- 3.41 microg/mL.

TL;DR: Two dimeric stilbene glycosides were isolated from an aqueous extract of the root of Polygonum cuspidatum and show strong inhibition of lipid peroxidation, but show no cytotoxic, DNA-cleavage activities and no inhibition of protein tyrosine phosphatase 1B.

TL;DR: In this paper, a lead compound for doing R&D of novel anti-HIV and hepatitis B virus medicines and also a novel medicine source for clinic application, thus having a significant value to develop and utilize the medical plant resources of our country.
