Sesuiterpene Lactones of Artemisia sylvatica

The phytochemical study of the aerial parts of Artemisia slyvatica(Asteraceae) led to the isolation of nine sesquiterpene lactones, 1-alpha-hydroperoxy-rupicolin A acetate(1), rupicolin B acetate(2), rupicolin A acetate(3), 1-alpha-hydroxy-4-alpha-hydroperoxy-bishopsolicepolide(4), 1-alpha-hydroperoxy-4-beta-hydroxy-8-alpha-acetoxy-guaia-2,9,11(13)-triene-6-alpha,12-olide(5), 1-alpha-hydroperoxy-4-alpha-bishoplicepolide(6), 1-alpha-4-beta-dihydroxy-8-alpha-acetoxy-guaia-2,9,11(13)-triene-6-alpha-12-olide(7), rupicolin A(8) and 1-alpha-4-alpha-dihydroxybisphopsolicedpolide(9). Their structures were established by chemical and spectroscopic methods.
