[Study on flavonoids from leaf of Ipomoea batatas].
摘要
OBJECTIVE: To investigate the flavonoid constituents of Ipomoea batatas. METHOD: 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. RESULT: Five compounds were isolated and identified as: tiliroside (I), astragalin (II), rhamnocitrin (III), rhamnetin (IV) and kaempferol (V). CONCLUSION: All of these five compounds were obtained from this plant for the first time.
