Solasodine and diosgenin have been widely used as starting materials for the partial synthesis of cortisone, progresterone and C21 steroidal derivatives (oral contraceptives). This study involved the total 1 H and 13 C spectral assignments of these two important compounds by using two‐dimensional NMR techniques (COSY, CSCM and HMBC), and resulted in unambiguous spectral assignments, especially in the convoluted regions of the spectra ( 1 H, 0.7–2.0 ppm; 13 C, 28–35 ppm).
