Flavonoids of willow herb (Chamerion angustifolium (L.) Holub) and their radical scavenging activity during vegetation.

Purpose: Willow herb has been traditionally used in folk medicine and currently it is a potential raw material for production of phytopharmaceuticals. The aim of this work was to determine the highest amount of flavonoids and the highest radical scavenging activity of willow herb, which was collected in different vegetation phases (intensive growing, bud, massive blooming, ripening of fruits (seeds) and the end of vegetation) and in different parts of the plant (blooms, leaves and stems).

Material/methods: Raw material was collected at Kaunas Botanical garden of Vytautas Magnus University.
