Abstract Two new steroidal alkaloids, veraussines A(1) and B(2) were isolated from the roots and rhizomes of Veratrum nigrum var. ussuriense. Their structures were determined as N-(ethoxycarbonyl)-1α, 2β, 3α, 15α-tetrahydroxy-5β-jervanin-12-en-11-one (1) and N-(methoxycarbonyl)-1α, 2β, 3α, 15α-tetrahydroxy-5β-jervanin-12-en-11-one(2)by spectroscopic analysis.
