Studies on the constituents of Calliandra anomala (KUNTH) MACBR. IV. Structure analysis by HPLC retention time and FAB-MS spectrum

Abstract

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.
