Abstract
Phytochemical screening of the stem bark of Zingiber officiale revealed the presence of tannins,flavonoids and alkaloids.
The bark of this species was macerated with 95% ethanol. A silica gel column developed with chloroform:methanol(3:2;v:v) gave apure flavonoid compound I. The structure of this isolate was elucidated using UV and IR data and The following partial structure was proposed:
