Bioguided fractionation of hypoglycaemic component in methanol extract of an study.

Nine components (C1-C9) were isolated from chloroform fraction of fractionated methanol extracts of leaves (FMEVA) by column chromatography. All the components C1 to C9 were purified and screened for hypoglycaemic activities in type-2 diabetic rats. The most potent hypoglycaemic component was elucidated on the basis of extensive spectroscopic (1D-, 2D-NMR, GC-MS, FTIR) data analysis.
