Abstract

From the bark of Juniperus chinensis Linn., a new labdane-type diterpene, methyl 14,15-dihydroxy-8(17),12E-labdadien-19-oate (1a), together with nine known compounds, trans-communic acid, cis-communic acid, 15,16-bisnor-13-oxo-8(17),11E-labdadien-19-oic acid, sandaracopimaric acid, 7-oxosandaracopimaric acid, sugiol, 7-oxototarol, alpha-cedrol and beta-sitosteryl-1-O-beta-glucopyranoside were isolated. The structures of those compounds were elucidated based on spectral analysis and chemical evidences.
