Studies on the constituents of Calliandra anomala (Kunth) Macbr. II. Structure elucidation of four acylated triterpenoidal saponins.
Four new triterpenoidal saponins, called calliandra saponins B (8), C (9), D (10), and F (12), were isolated from the branches of Calliandra anomala (Kunth) Macbr. The structures of these compounds were established on the basis of NMR spectra, FAB-MS, and the chemical evidence. These saponins, interestingly, have a N-acetyl glucosamine at the 3 position of the genin, and one or two monoterpene glycosides at the position of the sugar chain.
