}Two complex saponins, amole F and G, were characterized and their spectra were assigned using only 1D and 2D 1H and NMR methods. Amole F and G have seven and six monosaccharides, respectively, linked to the triterpene aglycone bayogenin. In addition to standard 2D methods, a series of TOCSY spectra with different mixing times and a high‐resolution coupled HSQC spectrum were particularly useful for assigning the monosaccharide units. It is concluded that saponins of this complexity are… CONTINUE READING
