Phytochemistry and Biological Properties of Burnet Weed (Sanguisorba spp.): A Review

Abstract

Great burnet (Sanguisorba officinalis L.) and small burnet (Sansguisorba minor Scop.) are edible, perennial weeds widely distributed in the world. These are the most widespread Sanguisorba species. The bioactive components of Sanguisorba plants include phenolics (phenolic acids, flavonoids and neolignans) and terpenoids. Large potential exists to use burnets as medicinal plants. Sanguisorba species are known to show anticancer properties, antioxidative, antimicrobial and antiviral activities. Also, Sanguisorba extracts show anti-Alzheimer and anti-inflammatory properties. Small burnet extracts could also be a useful alternative to synthetic fungicides for crop production. This review focuses on biological activities of Sanguisorba extracts and emphasizing their potential applications in pharmaceutical areas.
