Studies on the Constituents of Calliandra anomala (KUNTH) MACBR. I. Structure Elucidation of Two Acylated Triterpenoidal Saponins.

Six new triterpenoidal saponins, called calliandra saponins G(1), H(2), I(3), J(4), K(5) and L(6), 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 chemical evidence. These saponins, interestingly, have an N-acetyl glucosamine at the 3 position of the genin, and one or two monoterpene glycosides at the position of the sugar chain.
