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.
对杜松子甲醇提取物进行了植物化学研究。通过高效液相色谱 - 紫外检测法对粗提取物进行分析，并采用离心分配色谱法分离次要化合物。通过这种方法，分离出了五种二萜类化合物，其中一种是新的半日花烷型二萜15,16 - 环氧 - 12 - 羟基 - 8(17),13(16),14 - 拉布达三烯 - 19 - 酸。通过光谱方法，包括紫外光谱、核磁共振光谱、质谱和高分辨质谱，阐明了分离出的化合物的结构。
