  • Abstract Purified samples of two steroidal saponins produced by the starfish Asterias amurensis Lutken have been studied with respect to potency in irreversible blockade of contractural responses from the rat phrenic nerve-diaphragm preparation. The first, Asterosaponin A, is relatively more potent in blockade of indirectly elicited contraction (N-twitches) than against responses provoked by direct muscle stimulation (M-twitches); the second, Asterosaponin B, displays an inverted activity… CONTINUE READING
