[Metabolomic study of flower buds of Tussilago farfara in different development stages by GC-MS].

Objective: Plant metabolomics combined with GC-MS was used to investigate metabolic fingerprinting of Tussilago farfara at different growth stages.

Method: Dried Samples were extracted by two-phase solvent system to obtain polar and nonpolar parts, which were subjected to GC-MS analysis. Metabolites were identified by NIST data base search and comparison with the authentic standards.

Metabolomic profiling of the flower bud and rachis of Tussilago farfara with antitussive and expectorant effects on mice.

Ethnopharmacological Relevance: Flower bud of Tussilago farfara L. is widely used for the treatment of cough, bronchitis and asthmatic disorders in the Traditional Chinese Medicine. However, due to the increasing demands, adulteration with rachis is frequently encountered in the marketplace.
