Abstract:
Objective: To establish the chemical fingerprint of various secondary metabolites of Thymus vulgaris L., a culinary and medicinally important plant. Methods: Preliminary screening for various secondary metabolites was carried out. HPTLC profiles of various metabolites were done and profiles were developed for authentication. Result: The HPTLC chromatogram showed the presence of 9 Alkaloids, 11 Phenolic compounds, 11 Flavonoids, 10 Essential oils, 8 Tannins, 15 Triterpenes, 12 Steroids and 14 Saponins. Conclusion: The HPTLC fingerprint obtained can be used as a biomarker which is used for differentiating the species from the adulterant.
