Scutellaria lateriflora: The Polyphenolic Segment of the Metabolome of Aerial Organs

This study is a continuation of the investigation of the phenolic segment of the metabolome of Scutellaria lateriflora. The structural-class characterization and analysis of the distribution of polyphenolic metabolites, differing in the degree of methylation and glycosylation, in the aerial part of S. lateriflora introduced in the southern region of Primorskii krai are presented. The analysis showed that S. lateriflora predominantly accumulates nonmethylated glycosides, such as baicalein, as well as methylated flavones, including wogonin and 6-O-methylwogonin. The phenylethanoid verbascoside (caffeoyl-rutinoside dihydroxytyrosol), which is abundantly present in the plant roots, was detected in the aerial part of S. lateriflora in significantly lower quantities compared to flavonoids.
