摘要: Piper nigrum L. is commonly used worldwide and its pericarp, stalks, leaves will be major wastes materials. 42 amide alkaloids were identified in black, white pepper and pericarp by UHPLC-LTQ-Orbitrap HRMS method, followed by 40 constituents in stalks and 36 constituents in leaves. 8 amide alkaloids were reported for the first time in P. nigrum. An ultra-high-performance supercritical fluid chromatography (UHPSFC)-MS method was firstly applied to simultaneously determine 9 characteristic constituents (piperine, piperlonguminine, piperanine, pipercallosine, dehydropipernonaline, pipernonatine, retrofractamide B, pellitorine and guineensine). The most abundant compound in each extract was piperine with a concentration from 0.10 to 12.37 mg/g of dry weight. The fruits, pericarp and leaves extracts could improve cell viability in 6-OHDA-induced SK-N-SH and SH-SY5Y cells. The results showed the characteristics of amide alkaloids of different parts of P. nigrum and evaluated their neuroprotective activities.
