An echinocystic acid saponin derivative from Kalimeris shimadae

A new triterpene saponin, shimadoside A, has been isolated from Kalimeris shimadae and its structure deduced as 3-O-β-D- glucopyranosiduronic acid-3β-16α-dihydroxyolean-12-en-28-oic acid 28-O-β- D-xylopyranosyl-(1 → 3)-β-D-xylopyranosyl (1 → 4)-α-L-rhamnopyranosyl-(1 → 2)-β-D-xylopyranoside by means of spectral data, especially NMR, including COSY, HMQC, HOHAHA and ROESY techniques, and chemical degradation.

Study of Saponins from Albizzis lebbek Benth Flowers

Albizzia lebbek Benth flowers yield a number of saponins named as lebbekanin-D, F, G, and H.They are all glycosides of echinocystic acid with varying sugars.On the basis of enzymatic, partial alkaline hydrolysis, methylation and periodate oxidation studies, partial structures have been assigned to these saponins.

STRUCTURES OF 3,28-O-BISGLYCOSIDIC TRITERPENOID SAPONINS OF FATSIA JAPONICA

Four novel 3,28-O-bisglycosidic triterpenoid saponins were isolated from the mature fruits of F. japonica.They were characterized as the 28-O-α-L-rhamnopyranosyl-(1->4)-β-D-glucopyranosyl-(1->4)-β-D-glucopyranosides of 3-O-α-L-arabinopyranosyl echinocystic acid, 3-O-α-L-arabinopyranosyl hederagenin, 3-O-β-D-glucopyranosyl-(1->2)-α-L-arabinopyranosyl oleanolic acid and 3-O-β-D-glucopyranosyl-(1->2)-α-L-arabinopyranosyl hederagenin respectively. - Keywords: Fatsia japonica; Araliaceae; mature fruits; 3,28-O-bisglycidic triterpenoid saponins.
