title: Chemical constituents of Gentiana macrophylla Pall.
abstract: A novel dimeric secoiridoid glucoside, gentimacroside (1), and six known compounds (2-7) were isolated from the roots of Gentiana macrophylla Pall. Their structures were established on the basis of spectroscopic analysis, especially by means of 1D-, 2D-NMR and HRESIMS analyses.
