In a second investigation, this extract showed a promising antiproliferative effect against ovarian OVCAR-3 (total growth inhibition of 2.33 μg/mL) and glioma U251 (16.66 μg/mL) cells and acetylcholinesterase (AChE) inhibition (21% in the hippocampus) in the brain structures of rats; the total alkaloids’ content was quantified to be 25.4 μg/g [4]. Here, ACHE is linked to central nervous system cancer.
