|a Swainsonine (SW, 1), a unique indolizine with poly-hydroxyl groups, was re-isolated from the plant endophytic fungus Alternaria oxytropis. The structure (including planar structure and relative configuration) was systematically elucidated by NMR spectra (including 1 H, 13 C, 1 H-1 H COSY, HMQC, HMBC, and NOESY spectra in DMSO-d6 and in CD3 OD); 1 H NMR spectra of the modified Mosher's products were first used to determine the absolute configuration of SW. More importantly, the complex coupled features of H-7α, H-7β, and H-6α in the 1 H NMR spectrum of (1) were analyzed in details, which will provide aids for the planar and relative configuration determination of analogs
