Abstract
Two novel triterpenoidal saponins, called calliandra saponins A and E, were isolated from the branches of Calliandra anomala[a (KUNTH) MACBR . On the basis of the chemical and physicochemical evidence, their str uctures were defined as -(1-->6)-2-acetamido-2-deoxy-beta-D-glucopyran osyl echinocystic acid yl-2,7-octadienoyl-(1-->6)]-beta-D-glucopyranos yl} ester (4) and -(1-->6)-2-acetamido-2-deoxy-beta-D-glucopyranosyl e chinocystic acid -xylopyranosyl-(1-->4)]-alpha-L-rhamnopyranosyl-(1 -2 ',7'-octadienoyl-(1-->6)]-beta-D-glucopyranosyl} ester (5), respective ly.
