Pteryxin is a dihydropyranocoumarin derivative found in Apiaceae family. In this study, pteryxin, which was previously isolated from the fruits of Mutellina purpurea, was investigated for its inhibitory potential against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), which are the key
For the first time, the separation of coumarin derivatives from the petroleum ether extract of the fruits of Mutellina purpurea through high-performance countercurrent chromatography (HPCCC) is described. Four compounds, pteryxin (1; 2.72 mg), hyuganin C (2; 7.94 mg), osthol (3; 4.30 mg), and
