Phytochemical study of Glycyrrhiza pallidiflora Maxim.

Abstract

This article presents the results of the primary phytochemical study of Glycyrrhiza pallidiflora Maxim. introduced in the southeast of Western Siberia. The qualitative and quantitative composition of several primary and secondary metabolites in underground and aboveground organs of the plant were studied in different years of introduction and vegetation period. The presence of triterpene saponins, coumarins, chromones, chalcones, aurones, 5-oxy-flavones, 5-oxy-flavonols, flavan-3-ols, and proanthocyanidins was determined. The total content of phenolic compounds in the grass reached 2.83±0.22% and in the roots up to 0.77±0.27%. Eighteen proteinogenic amino acids were identified, including 8 essential and 10 nonessential amino acids. The seeds were found to accumulate 4.27±0.25% of fatty oils with a predominance of triglycerides of polyunsaturated acids.
