LC-MS/MS Analysis and Biological Activities of Different Parts of Ziziphora Capitate L.

Abstract

The Ziziphora species, classified under the Lamiaceae family, have a strong aromatic property. Ziziphora species have been used in folk medicine as sedative, gastric, aphrodisiac, bloating, and degassing. In the current study, the phenolic and flavanoid content of ethanol extracts of Ziziphora capitata L. species of flower, leaf, branch, mixed, and root parts was determined by the LC-MS/MS device. In addition, the antioxidant and cytotoxic activities of the extracts, as well as their inhibitory effects on enzymes (antihypertensive, AchE (acetylcholinesterase), BchE ( butyrylcholinesterase), elastase, tyrosinase, collagenase and urease), were determined. The LC-MS/MS results showed that quinic acid (25578, 5842, 25171, 14055, 10597 mu g g-1, respectively) was found in higher amounts in flower, leaf, branch, mixed, and root extracts of Z. capitata species compared to other components. Additionally, rosmarinic acid (17097 mu g g-1), cynaroside (8432), and hesperidin (8067) were found to be major components. It was observed that the flower extract of the species exhibited strong antioxidant activity (IC50: 37.18 +/- 1.36 mu g mL-1, 9.89 +/- 0.45, A0.5:16.27 +/- 0.02, respectively) in DPPH, ABTS and CUPRAC methods. It was concluded that the leaf extract of Z. capitata species had a strong cytotoxic effect on HT-29 (colon cancer cell line) (viability %: 9.26 +/- 0.69). It was observed that the root part of the species exhibited higher activity in butyrylcholinesterase (BChE) enzyme inhibition activity (inhibition %: 40.56 +/- 0.88) than other parts. It was determined that Z. capitata extracts did not show acetylcholinesterase, urease, tyrosinase, elastase, collagenase, and antihypertensive enzyme activity or showed low activity. As a result, it is thought that the flower extract of the Z. capitata species has better results in terms of the examined parameters, whereas the leaf extract needs to be subjected to more detailed in vitro and in vivo research conducted to be used in the pharmaceutical industry as a result of its cytotoxic effect against colon cancer cell lines.
