About the content of flavonols in leaves of some species of Spiraea in the North (Republic of Komi)

Abstract

For the first time the content of flavonols in the leaves of Spiraea plants introduced in the Botanical garden and in the leaves of one sample of the wild species Spiraea media in the North (Komi Republic) was determined. The total content of flavonols among the species of Spirea varies from 1.8% to 5.7%. The widespread Eurasian species of Spiraea media has high flavonols content - from 4.8 to 5.1% in the introduced sample and lower in the local sample - 3.5%. Spiraea species can be a raw source of flavonols.
