摘要：

Extracts of the heartwood of Juniperus formosana HAYATA were found to contain the known constituents beta-sitosterol, chi-cedrol, 4-ketocedrol, 3-beta-hydroxycedrol, isocedrolic acid, sigma-cadinol, cadin-8-en-10-ol, clovandiol, sugiol, Delta-5-dehydrosugiol, totarol, 7-oxototarol, cryptojaponol, emodin, and methyl chi-conidendral, together with five new compounds, 7-chi-methoxydeoxocryptojaponol, suginal, detetrahydroconidendrin, formosanol, and junipediol. In addition, 7-beta-hydroxydeoxocryptojaponol was obtained (first isolation as a natural product). Junipediol has a novel sesquiterpene skeleton which was elucidated by X-ray analysis.
