The anti-Alzheimer's disease properties of CSO were determined by inhibition of acetylcholinesterase enzyme and its IC₅₀ value (17.60 µg/mL) was found to be close to the IC₅₀ value of tacrine (8.82 µg/mL), the standard inhibitor of the enzyme. Inhibition properties of α-glycosidase enzyme and human carbonic anhydrase II isoenzymes were also studied. It was understood that CSO inhibited both enzymes at a lower rate than standard inhibitors.

In addition, LC-HRMS chromatography application was performed to understand the phenolic content of CSO.
