摘要
Two new steroidal saponins, named anemarnoside A (1) and anemarnoside B (2), along with three known compounds, timosaponin J (3), timosaponin B II (4), and timosaponin B (5), have been isolated from Anemarrhena asphodeloides. Their structures were established by spectroscopic techniques (IR, MS, 1D NMR, and 2D NMR) and by comparison with published data.
