目的：对新疆圆柏枝叶的化学成分进行研究。方法：采用硅胶、大孔吸附树脂和Sephadex LH-20等色谱方法进行分离,利用理化性质和波谱技术鉴定化合物结构。结果：分离纯化得到5个化合物,分别鉴定为：槲皮素-3-O-（6″-O-乙酰基）-β-D-吡喃葡萄糖苷（1）、海波拉亭-7-O-β-D-吡喃葡萄糖苷（2）、异槲皮苷（3）、4-表-松香酸（4）、β-谷甾醇（5）。结论：其中,化合物1~3为首次从该属植物中分离得到。

英文摘要：

Objective： To isolate and determine chemical constituents from twig and leaf of Juniperus sabina. Methods： Five compounds were isolated and purified by extraction and different kinds of column chromatography. The structures were determined on the basis of the physicochemical properties and spectral analysis. Results： The structures were elucidated as quercetin-3-O-（ 6″-O-acetyl）-β-D-glucopyranoside（ 1）,hypolaetin-7-O-β-D-glucopyranoside（ 2）,isoquercetin（ 3）,4-epi-abietic acid（ 4）,β-sitosterol（ 5）. Conclusion： Compounds 1 ~ 3 are obtained from Juniperus genus for the first time.
