From the aerial roots of the medicinal plant Geranium sanguineum L. a polyphenol-rich extract with strong anti-influenza activity has been isolated. [...] Key Method To investigate its active fractions, the extract was partitioned by solvents with increasing polarity. The n-BuOH fraction contained the majority of the in vitro antiviral activity; the EtOAc fraction was the most effective one in vivo.Expand

Polyphenols from Bulgarian medicinal plants with anti-infectious activity.
TLDR
Three Bulgarian medicinal plants--Geranium macrorrhizum, G. sanguineum, and Epilobium hirsutum were analyzed phytochemically and the effect of the extracts on the reproduction of influenza viruses in vitro, in ovo, and in vivo was established. Expand
In vitro anti-influenza virus activity of a plant preparation from Geranium sanguineum L.
TLDR
A polyphenolic complex, isolated from the Bulgarian medicinal plant Geranium sanguineum L., was shown to have selective anti-influenza activity in vitro and the selectivity of antiviral action was confirmed by the variation in sensitivity of different influenza viruses to PC and the selection of variants with reduced drug sensitivity.
