Abstract

The ethyl acetate and methanol extracts from aerial parts of Tanacetum balsamita yielded a new derivative of 1-acetyl-erivanin, namely 1-acetyl-3-epi-erivanin (17), some known compounds, namely seventeen sesquiterpene lactones, five flavonoids, four coumarins, and a steroid. All extracts displayed antibacterial activity against test microorganisms except for Escherichia coli. The methanol (TBM) extract with an IC50 value of 0.180 mg/mL exhibited good antioxidant activity against DPPH radical while all extracts showed significant anti-inflammatory activity against lipoxygenase enzyme. The ethyl acetate (TBEA) extract presented moderate activity against alpha-glucosidase enzyme with an IC50 of 0.808 mg/mL. The highest total phenol content with 91.050 mg GAE/g extract was found in TBM. It is the first study on the isolation of secondary metabolites as well as 5-lipoxygenase and alpha-glucosidase inhibitory activity of T. balsamita growing in Turkey.
