This method is based on chemical markers, constituents, or compounds present in the substance, resulting in a distinct chemical “fingerprint” or profile that distinguishes it from others. By comparing the chemical fingerprint/MSFP of a sample against established references or standards, it becomes possible to ascertain the authenticity of the sample or detect potential adulteration.

It is a web-based digital library of Indian medicinal plants and their metabolites (a bioinformatics tool) or a reference library of MSFPs.

A unique, characteristic profile of peaks representing the mass-to-charge ratios and signal intensities of molecules or a unique mass spectrum pattern derived from a sample. It is widely used in analytical chemistry, proteomics, and botanical authentication by matching experimental spectra against reference libraries.
