Isolation and Structure Identification of the Novel Alkaloid Constituent from Epimedium Koreanum Naki

Abstract

Abstract: Anovel kind of alkaloid was isolated from the aerial of Epimedium koreanum Naki. The molecular weight and molecular formula were achieved by FT-ICRMS as 370.1285012 and C₂₀H₂₀O₆N. The molecular structure of the compound C₂₀H₂₀O₆N was determined on the basis of spectral analyses as 6-hydroxy-11,12-dimethoxy-2,2-dimethyl-1,8-dioxo-1,3,4,8-tetrahydro-2H-7-oxa-2-azonia-benzo phenanthene. Using electrospray ionization multi-stage mass spectrometry, the structure was confirmed further. The compound was first reported from this kind of plant.

Key words: Epimedium koreanum Naki, Alkaloid, NMR, Electrospray ionization mass spectrometry
