Leucanthoside A, a new allose‐containing triterpenoid saponin (1), was isolated from the aerial parts of Cephalaria leucantha L. Its structure was determined by electrospray ionization mass spectrometry and NMR spectroscopy. Complete assignments of the 1 H and 13 C NMR chemical shifts were achieved by two‐dimensional NMR experiments: DQF‐COSY, NOESY, TOCSY, HSQC, DINE‐HSQC, HMBC, 13 C‐ 1 H 2D‐ J ‐resolved spectroscopy, and 1,1‐ADEQUATE.
