This study reports a comprehensive metabolomic profiling of an antidiabetic (evaluated in vivo in rats) polyherbal formulation using NMR, FTIR and LIBS (Laser Induced Breakdown Spectroscopy). The proton spectrum showed primary and secondary metabolites, many of which were further validated using FTIR spectroscopy. LIBS spectrum revealed the presence of elements such as Na, K, H, Mg and Ca. The presence of primary and secondary metabolites in NMR and FTIR spectra, and that of Mg and Ca in LIBS spectrum indicate their possible roles in the antidiabetic activity of the formulation. Mg and Ca are known to regulate blood glucose level.
