Studies on the constituents of Calliandra anomala (KUNTH) MACBR. II. Structure elucidation of four acylated triterpenoidal saponins

, p. 1111 - 1115 (2007/10/02)
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.

On the basis of chemical transformations and physicochemical characteristics of the compounds obtained it has been established that codonoside B - the main triterpene glycoside of Codonopsis lanceolata (Sieb. et Zucc.) Benth. et Hook., has the structure of echinocystic acid 3-O-β-D-glucopyranuronoside 28-O- 4)-O-α-L-rhamnopyranosyl-(1 -> 4)-O-β-D-glucopyranosyl-(1 -> 2)-α-L-arabinopyranoside>.

Activity-guided fractionation of the MeOH extract of the fruits of Tetrapleura tetraptera TAUB. (Mimosaceae) afforded 4 saponins 1-4, which exhibited strong molluscicidal properties against the schistosomiasis-transmitting snails Biomphalaria glabrata.Chemical, enzymatic, and spectral methods (DCI-MS, 1H-NMR, 13C-NMR) showed that they were N-acetylglycosides of oleanolic acid and of echinocystic acid.Apart from saponin 1 (aridanin), previously isolated from this plant, glycosides 2-4 are new naturally occuring compounds.
Constitution of scheffleroside: a spermicidal saponin from Schefflera capitata.
Jain,Sarin,Khanna
, p. 1139 - 1141 (2007/10/10)
While screening Indian plants for biological activities, it was observed that a 2% aqueous solution of the crude 70% aqueous ethanolic extract of Schefflera capitata showed significant activity against both rat and human spermatozoa. The new saponin, melting point 230-232 degrees, gives on acid hydrolysis D(+)-fucose (1 mole), D(+)-galactose (1 mole), D(+)-glucoronic acid (1 mole) and echinocystic acid (1 mole). Its structure has been tentatively assigned to scheffleroside.
