Eudesmane alcohols from jasonia glutinosa

Pascual Teresa,Barrero,San Feliciano,Medarde

, p. 2155 - 2157 (1980)

Three new sesquiterpene alcohols have been isolated from Jasonia glutinosa. Their structures were elucidated by spectroscopic methods and chemical correlations as (-)-[11R]-4α,14-epoxyeudesm-11,12-diol, (-)-[11R]-eudesm-4(14)-en-5β,11,12-triol and (+)-[11R]-eudesm-4(14)-en-5α,11,12-triol and they are called α-epoxy kudtdiol, 5-epi-kudtriol and kudtriol respectively.
