Antimicrobial activity of Viola tricolor herb

Violets of the section Melanium, their colonization by arbuscular mycorrhizal fungi and their occurrence on heavy metal heaps

“…Moreover, this species is indigenous to or naturalized in large parts of Europe, the Middle East, Central Asia, the U.S.A. (Rimkienė et al, 2003) and even Korea (Choi et al, 1996). V. tricolor has been used in folk medicine against respiratory problems such as bronchitis, asthma and cold symptoms (Rimkienė et al, 2003), exhibits antioxidative activities (Vukics et al, 2008), has cytotoxic effects on human cancer cell lines (Svangård et al, 2004) and antimicrobial activity (Witkowska-Banaszczak et al, 2005).…”

Use of natural products in anticytokine therapy

“…The antiinflammatory effect of pansy herb is probably related to the presence of triterpenoid saponins [8]. Moreover, extracts of pansy herb exhibit direct antimicrobial activity [12], but the mechanism of this effect remains unknown. The antiinflammatory effect of calendula preparations is also associated with high content of triterpenoid alcohols [1].…”

Dereplication of natural products from complex extracts by regression analysis and molecular networking: case study of redox-active compounds from Viola alba subsp. dehnhardtii

“…Violets contain various natural products with diverse biological activities (Muhammad et al 2012). These include anti-inflammatory, antimicrobial (Witkowska-Banaszczak et al 2005) and, predominantly, antioxidant activity . Previous work describes over 200 compounds in this genus, mainly flavonoids, terpenoids and phenylpropanoids (Zhu et al 2015).…”
