Evaluation of anti-oxidant and acetylcholinesterase activity and identification of polyphenolics of the invasive weed Dittrichia viscosa.

Introduction: The bioactive metabolites derived from weeds have attracted the interest of the food and pharmaceutical industries due to their health benefits.

Objective: To evaluate the anti-oxidant and acetylcholinesterase activity of Dittrichia viscosa extracts and characterise the polyphenolic metabolites using the LC coupled with diode-array detection (DAD) and positive mode electrospray ionisation (ESI) MS method with a view to evaluating the exploitation potential of this invasive weed.

Materials And Methods: Roots and aerial parts of D.
