C. Tani et al., STUDIES ON THE CONSTITUENTS OF CALLIANDRA-ANOMALA (KUNTH) MACER - IV - STRUCTURE-ANALYSIS BY HPLC RETENTION TIME AND FAB-MS SPECTRUM, Chemical and Pharmaceutical Bulletin, 46(4), 1998, pp. 723-725
Three new triterpenoidal saponins were isolated from the branches of C
alliandra anomala (KUNTH) MACBR. On elucidation of their structures, w
e noticed correlations between a series of structures and their HPLC r
etention time. By this behavior and the FAB-MS spectrum, the structure
s of three saponins (calliandra saponin M, N and O) were established.
