Abstract
The study investigates the relationship between soils
that vary for different basic physicochemical parameters (pH,
phosphorus and potassium content, granulometric composition
and soil organic matter content) and the free amino acids con-
tent of Stellaria media. According to some research, plant amino
acid profile is a good indicator of the condition of the soils on
which plants are grown. In this experiment, a rapid and sensitive
liquid chromatography coupled with tandem mass spectrometry
(LC-MS/MS) method was used for the identification and quanti-
fication of nineteen proteinogenic amino acids in Stellaria media
samples, which is a very common weed found worldwide. Signif-
icant linkage was found between the soil parameters and Stellaria
media amino acid content. Garden soil is the most favourable soil
for amino acid content. Glutamine, glutamic and aspartic acid are
the most abundant amino acids in Stellaria media grown on all
three tested soils.
