Abstract

Six totarol derivatives were isolated from the extract of the root of Juniperus chinensis LINN. Three known components were identified as totarol, totarolone, and 7-oxototarol. The structures of three new totarol derivatives, 1, 3-dioxototarol, isototarolenone, and 1-oxo-3β-hydroxytotarol, were elucidated on the basis of spectral data and chemical transformation.
