Veramadines A and B, New Steroidal Alkaloids from Veratrum maackii var. japonicum

Two new steroidal alkaloids possessing a cevanine-type skeleton, veramadines A (1) and B (2), were isolated from the aerial parts of Veratrum maackii var. japonicum. The structures of 1 and 2 were elucidated on the basis of their spectroscopic data.
