Comparative yield and characterization of flavonoids from the stem back and root of Blighia sapida

Abstract

Flavonoids represent a wide spread group of water soluble phenolic derivatives, known for their medicinal effect. This paper is focused on identifying the functional groups present in flavonoids of Blighia sapida stem bark and root sample. The percentage yield was higher with methanol extract of the stem bark compared to the root. The GC-MS of methanol extract shows carboxylic acid which might be attributed to presence of lipids. The isolation of flavonoids by TLC and the FITR revealed the functional group –OH, C=O,CH which are majorly responsible for the medicinal effect.
