title: A new guaianolide from Artemisia roxburghiana.
abstract: A new member of 5αH,6βH,7αH,11αH-guaian-12,6α-olides, 11-epi-8α-hydroxyarborescin, together with a mixture of (24R)- and (24S)-cycloart-25-en-3b,24-diols, palmitic acid and 1-octacosanol were isolated from the leaves of Artemisia roxburghiana Bess. (Asteraceae) of Vietnam. Their structures were determined on the basis of spectroscopic methods.
