T. Nakamura et al., STUDIES ON THE CONSTITUENTS OF CALLIANDRA-ANOMALA (KUNTH) MACBR .2. STRUCTURE ELUCIDATION OF 4 ACYLATED TRITERPENOIDAL SAPONINS, Chemical and Pharmaceutical Bulletin, 42(5), 1994, pp. 1111-1115
Four new triterpenoidal saponins, called calliandra saponins B (8), C
(9), D (10), and F (12), were isolated from the branches of Callinndra
anomala (KUNTH) MACBR. The structures of these compounds were establi
shed on the basis of NMR spectra, FAB-MS, and the chemical evidence. T
hese saponins, interestingly, have a N-acetyl glucosamine at the 3 pos
ition of the genin, and one or two monoterpene glycosides at the posit
ion of the sugar chain.
