摘要
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）- 1 α,2β,3α, 15α-tetrahydroxy-5fl-jervanin- 12-en- 11 -one （1） and N-（methoxycarbonyl）-1α,2β,3α,15α-tetrahydroxy-5/3-jervanin-12-en-1 l-one （2） by spectroscopic analysis.
