Geranium robertianum L. introduction, biologically active compounds in overground

Abstract

The introduction of the medicinal (aromatic) plants, their diversity are increased and the genetic medicinal plant resources are accumulated. It is important to determine the regularity of the accumulation of biologically active compounds in different stages of vegetation, introduced in medicinal, spice (aromatic) plants. The dynamics of their qualitative and quantitative indicators of their biologically active compounds determines the shelf life of the medicinal plant raw material and its quality [4]. The aim of these chemical analyses is to determinate total content of phenolic compounds, total content of flavonoid compounds and radical scavenging activity of Geranium robertianum L. methanolic extracts in the different vegetation periods: intense growth, flower buds, start blossoming, massive blossoming, end of blossoming. The object of these analyses is G. robertianum L. It is a annual, sometimes biennial herbaceous plant of Geraniaceae family can be found widely in Europe, with the exception of the far north, in temperate parts of Asia, North Africa, Atlantic area of North America, and temperate parts of South America [1]. In Lithuania G. robertianum L. grows in humid deciduous or mixed forests, bushes, ash, roadsides. The metanolic extracts studied come from Sector of Medicinal Plants, Kaunas Botanical Garden of Vytautas Magnus University were harvested during the year 2016.[...]
