tiliroside and astragalin

Abnormal glycosylation of cancer cells is considered a key factor of carcinogenesis related to growth, proliferation, migration and invasion of tumor cells. Many plant-based polyphenolic compounds reveal potential anti-cancer properties effecting cellular signaling systems. Herein, we assessed the effects of phenolic acid,

To investigate the flavonoid constituents of Ipomoea batatas.. The leaf was extracted with EtOH and partitioned with CHCl3, EtOAc and n-BuOH respectively. The chemical components of EtOAc fraction were isolated by silica gel and sephadex LH-20 column chromatography. The chemical structures were elucidated on the basis of physic-chemical properties and spectral data.. Five compounds were isolated and identified as: tiliroside (I), astragalin (II), rhamnocitrin (III), rhamnetin (IV) and kaempferol (V).. All of these five compounds were obtained from this plant for the first time.
