摘　　要：目的　进一步研究枫香槲寄生的化学成分,寻找抗心血管病的活性成分。方法　应用柱色谱法进行分离、纯化,根据理化性质和光谱数据鉴定结构。结果　得到 5个化合物:反式桂皮酸(trans cinnamicacid) (I),齐墩果酸(oleanolicacid) (II),白杨素(chrysin) (III),圣草酚 (eriodictyol) (IV),枫香槲寄生苷 (V)。结论　V为新化合物,I-IV均为首次从枫香槲寄生中分离得到,其中I,III,IV为首次从桑寄生科植物中分离得到。Aim To study the chemical constituents of Viscum liquidambaricolum Hayata. Methods Various chromatographic techniques were used to separate and purify the compounds.Their spectral data (MS,IR,NMR) were measured for structure identification. Results Five compounds were isolated from Viscum liquidambaricolum and their structures were identified as trans-cinnamic acid (I), oleanolic acid (II), chrysin (III), eriodictyol (IV) and liquidamboside (V). Conclusion Liquidamboside (V) is a new compound, the known compounds I-IV were isolated from this plant for the first time, I, III, IV were isolated from Loranthaceae for the first time.
