Anticancer, Antioxidant, Antimicrobial and Enzyme Inhibitory Activities of Inula aucheriana

The Inula aucheriana, of the Asteraceae family, is widespread in Turkey. The aim of this study was to investigate different biological properties and thereby reveal the pharmacological potential of this plant, which is already known to be used in the treatment of various diseases,. Following the preparation of 80% ethanol extract from I. aucheriana, qualitative and quantitative methods were used to investigate the chemical composition (Q-TOF analysis), antioxidant (spectrophotometric analysis), inhibitory enzyme (Ellman's method), antimicrobial (MIC concentration value), and anti-cancer (XTT analysis) activities. The results showed that 80% ethanol extract from I. aucheriana was a potent antioxidant, with anti-cancer and enzyme inhibitor effects. In the chemical composition analysis, the primary compound of the extract was determined to be luteolin (32.55%). I. aucheriana extract was seen to have AChE and BChE inhibition, , and when compared with the reference drug, the extract was determined to have an inhibitory effect an enzyme called alpha-glucosidase. Besides, relatively high tyrosinase enzyme inhibition was also detected. The extract significantly showed antiproliferative activity on the MDA-MB-231 cells at 0.0625 mg/mL and higher concentrations,for 24 hours in a a dose-dependent manner.This study is the first to evaluate enzyme inhibitory effect and antioxidant activity of I. aucheriana.
