[Study on flavonoids from leaf of Ipomoea batatas].
Zhongguo Zhong Yao Za Zhi. 2005 Apr; 30(7):516-8.ZZ

Abstract

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.
