Abstract:
The flavonoids of the bark of Khaya senegalensis was
investigated. Extraction of the barks with 95% ethanol gave a
crude product, which was fractionated over silica gel developed
with benzene: methanol (4:1). Only a single flavonoid was
detected under UV light.
The structure of the flavonoid was elucidated on the
basis of its spectral data and the following structure was
proposed:
