A phytochemical study of the methanol extract of Juniperus communis berries was undertaken. The crude extract was analysed by HPLC‐UV and the isolation of the minor compounds was performed by centrifugal partition chromatography. By this means, five diterpenes were isolated, one of which was a new labdane diterpene 15,16‐epoxy‐12‐hydroxy‐8(17),13(16),14‐labdatrien‐19‐oic acid. The structures of the isolated compounds were elucidated by spectroscopic methods, including UV, NMR, MS and HR‐MS. Copyright © 2005 John Wiley & Sons, Ltd.
