The plasma extract of “Banaba capsules” were
injected into the LC-MS/MS system and the quantity of
asiatic acid and corosolic acid were determined in
terms of the percentage. The assay values were found
to be 0.88 % and 0.31% for Corosolic acid and Asiatic
acid respectively in the dietary supplement. The
method is specific because it resolved both the
standards well in the presence of other phytochemicals
in the formulation. The method was found to be
suitable for qualitative and simultaneous quantitative
analysis of Corosolic acid and Asiatic acid from the
formulation spiked in human plasma.
