中文摘要：

目的研究薜荔茎的化学成分。方法采用硅胶、Sehadex LH-20、ODS、HPLC等色谱技术进行分离纯化,然后通过理化性质和波谱数据鉴定所得化合物的结构。结果从薜荔茎乙酸乙酯部位中分离得到9个化合物,经鉴定分别为佛手柑内酯（1）、β-谷甾醇（2）、6α-羟基豆甾-4-烯-3-酮（3）、6β-羟基豆甾-4-烯-3-酮（4）、3β-羟基豆甾-5-烯-7-酮（5）、4-acetonyl-3,5-dimerhoxy-p-quinol（6）、胡萝卜苷（7）、柚皮素（8）、金圣草黄素（9）。结论化合物3、4、5和9均为首次从该植物中分离得到,化合物1和6为首次从该属植物中分离得到,并首次对化合物6的碳谱数据进行了归属。

英文摘要：

AIM To investigate the chemical constituents from the stems of Ficus pumila. METHODS The compounds were isolated by silica gel,Sephadex LH-20,ODS and HPLC column chromatography. Then their structures were elucidated by physicochemical properties and spectral data. RESULTS Nine compounds were isolated and elucidated as bergaten（ 1）,β-sitosterol（ 2）,6α-hydroxystimast-4-ene-3-one（ 3）,6β-hydroxystimast-4-ene-3-one（ 4）,3β-Hydroxysitost-5-en-7-one（ 5）,4-acetonyl-3,5-dimerhoxy-p-quinol（ 6）,daucosterol（ 7）,（ S）-naringenin（ 8） and chrysoeriol（ 9）. CONCLUSION Compounds 3,4,5 and 9 are firstly isolated from this plant. Compounds 1 and 6 are obtained from this genus for the first time,and it is the first time that the13 C spectroscopic data of compounds 6 are identified.
