Chromatographic Study of Phenolic Compounds in Medicinal Plants Alchemilla subcrenata Buser and Veronica chamaedrys L.

Abstract

The objects of investigation were leaves and inflorescences of Alchemilla subcrenata and Veronica chamaedry, growing on the left bank at 700 m from the edge of Lake Baikal. Some small differences in the quantity and quality of phenolic compounds in the leaves of one species even selected at one time were found. At the same time, differences in the quantity and quality of phenolic compounds in the different times of the day were even more pronounced. In the inflorescences of Alchemilla subcrenata the dynamics of flavonoids has been characterized by more stable composition than in its leaves. For Veronica's tissues and organs more variety of seasonal cocktail of phenolic compounds than in the Alchemilla subcrenata was detected. Expect a variety of phenolic compounds in inflorescences of Veronica seasonal cocktail was higher than in the leaves.
