Phenolic compounds of Bistorta alopecuroides (Turcz. ex Meissn.) Kom. (Polygonaceae) from different populations of Siberia and the Far East
Maria, Voronkova | Galina, Vysochina
The article considers research of the phenolic compounds composition and content in leaves of Bistorta alopecuroides (Turcz. Ex Meissn.) Kom. from different populations using HPLC methods. It shows that B. alopecuroides component composition is quite variable and depends on many environmental factors, such as microclimate, altitude, technogenic pollution. Isovitixin, rutin and flavonolglycoside (tR = 9.2 min; UV 273, 355 nm) compounds are found in B. alopecuroides leaves of all studied populations. B. alopecuroides growing in high mountains and under technogenic pollution conditions have the highest content of phenolic compounds, which confirms their adaptive role in plant metabolism. The total content of phenolic compounds in leaves of B. alopecuroides plants reaches 20.82mg/g.
