Chemical Diversity of Bastard Balm ( L.) as Affected by Plant Development.

The phytochemical diversity of was investigated in terms of seasonal changes and age of plants including plant organs diversity. The content of phenolics, namely: coumarin; 3,4-dihydroxycoumarin; -coumaric acid 2--glucoside; verbascoside; apiin; luteolin-7--glucoside; and -coumaric; -coumaric; chlorogenic; caffeic; ferulic; cichoric acids, was determined using HPLC-DAD. Among these, luteolin-7--glucoside, verbascoside, chlorogenic acid, and coumarin were the dominants.

Effect of Shading on Development, Yield and Quality of Bastard Balm Herb ( L.).

The aim of the study was to assess the effects of shading on its development and accumulation of phenolics. Their content (verbascoside, apiin, luteolin-7--glucoside, coumarin, 3,4-dihydroxycoumarin, -coumaric acid 2--glucoside as well as -coumaric, -coumaric, chlorogenic, caffeic, ferulic and cichoric acid) was determined in the herb using HPLC-DAD. The results showed that the content of abovementioned flavonoids and phenolic acids was highest in plants grown under full sunlight.

Phenolics in L. and (L.) Hill Raw Materials.

L. and (L.) Hill represent medicinal plants used for the production of herbal teas and preparations with antioxidant and expectorant activity.
