Abstract

Caraganaphenol A (1), a new tetrameric stibene, was isolated from the root of Caragana chamlagu LAMARK (Leguminosae) along with (+)-α-viniferin (2) and kobophenol A (3). The stereostructure of 1 was suggested using NMR techniques (¹H-detected heteronuclear multiple quantum coherence (HMQC), ¹H-detected heteronuclear multiple bond connectivity (HMBC), and nuclear Overhauser effect (NOE) difference spectra).
