improved method for the evaluation of Adhatoda vasica
extract by quantitation of major
metabolite vasicine. The plant powder was extracted with methanol and
evaporated in vaccuo to obtain an
oily residue.
The residue was diluted with aqueous solution of citric acid (1%) and was
further extracted with chloroform.
The preliminary screening for alkaloid was done with alkaloidal reagents and
the presence of vasicine was assessed by thin layer chromatography (TLC). The extractive was then subjected to
column chromatography using a mixture of ethyl acetate and methanol adjusted to
pH 9.5 with liquid ammonia as mobile phase. The TLC chromatograms of the
collected column fractions were developed and the fractions indicated the
presences of vasicine were combined together. The residue obtained from
evaporation of solvent was subjected to preparative TLC along with reference
standard to get pure crystalline vasicine. The compound vasicine was
ascertained by UV-Vis, FT-IR and LCMS/MS analyses. The quantitative estimation
of vasicine was carried out by reversed phase HPLC method. About 99.50% of pure
vasicine (647 mg) compared to reference standard was obtained from 250 gm of
leaf powder (0.2588% w/w).</span
