L. Sindhu and R. Neelamegam*

ABSTRACT

Methanol extracts of Malachra capitata root, stem and leaf samples were analyzed for the quantification flavonoid profile using HPLC. The results of HPLC analysis indicate the presence of flavonoid compounds -gallic acid, caffeic acid, rutin, quercetin and ferulic acid in the root sample methanol extracts of Malachra capitata while the methanol extract of leaf sample shows only two compounds (rutin and ferulic acid) and one compound (gallic acid) in the stem sample methanol extract. Maximum amount of flavonoid compound (gallic acid -30mg/g) noted in the stem sample as compared to other compounds among the plant samples tested.
