on NMR results, the compound's structure is identical to that of vanicoside A, comprising four
phenylpropanoid ester units and a sucrose unit. The structure differences were located at C-
3 ″″′. The cytotoxic activity of polygonumins A was evaluated on several cancer cell lines
by a cell viability assay using tetrazolium dye 3-(4, 5-dimethylthiazol-2-yl)-2, 5-
diphenyltetrazolium bromide (MTT). The compound showed the highest antiproliferative (p< …
