Influence of selected soil parameters on amino acid profile in Stellaria media

The study investigates the relationship between soilsthat vary for different basic physicochemical parameters (pH,phosphorus and potassium content, granulometric compositionand soil organic matter content) and the free amino acids content of Stellaria media. According to some research, plant aminoacid profile is a good indicator of the condition of the soils onwhich plants are grown. In this experiment, a rapid and sensitiveliquid chromatography coupled with tandem mass spectrometry(LC-MS/MS) method was used for the identification and quantification of nineteen proteinogenic amino acids in Stellaria mediasamples, which is a very common weed found worldwide. Significant linkage was found between the soil parameters and Stellariamedia amino acid content. Garden soil is the most favourable soilfor amino acid content. Glutamine, glutamic and aspartic acid arethe most abundant amino acids in Stellaria media grown on allthree tested soils.
