title: A new sesquiterpene from the roots of Vladimiria souliei.
abstract: A new sesquiterpene lactone, 1beta-hydroxy-4alpha-methoxy-5alphaH, 7alphaH, 6betaH-eudesm-11(13)-en-6, 12-olide 1, and three known compounds, 4alpha-hydroxy-5alphaH, 7alphaH, 6betaH-eudesm-11(13)-en-6, 12-olide 2, mokko lactone 3, beta-sitosterol 4 were isolated from the roots of Vladimiria souliei. Their structures were elucidated by spectroscopic methods.
