Studies on the constituents of Calliandra anomala (Kunth) Macbr. IV. Structure analysis by HPLC retention time and FAB-MS spectrum.
Kampo Division, Teikoku Seiyaku Co., Ltd., Tokushima, Japan.
Three new triterpenoidal saponins were isolated from the branches of Calliandra anomala (KUNTH) MACBR. On elucidation of their structures, we noticed correlations between a series of structures and their HPLC retention time. By this behavior and the FAB-MS spectrum, the structures of three saponins (calliandra saponin M, N and O) were established.
