中文摘要：

为了研究竹叶榕（Ficus stenophylla Hemsl．）根的化学成分，采用硅胶、Sephadex LH-20柱反复分离纯化，根据理化常数和波谱数据鉴定化合物的结构。从竹叶榕根的95％乙醇提取物中分离得到5个化合物，分别鉴定为竹叶榕素[methyl 3-（6．hydroxy-4．methoxybenzo-furan-5-yl）propanoate，1]、山柰酚（kaemferol，2）、山柰酚3-O-β-D-葡糖苷（kampferol 3-O-β-D-glucoside，3）、槲皮素（quercetin，4）和小麦黄酮（tricin，5）。其中化合物1为新化合物，化合物2～5为首次从该植物中分离得到。

英文摘要：

Chemical constituents of the roots of Ficus stenophylla were isolated and purified by repeated column chromatography on silica gel and Sephadex LH-20. Their structures were elucidated based on physicochemical and spectral data. Five compounds were identified as methyl 3-（ 6-hydroxy-4- methoxybenzofuran-5-yl） propanoate （1）, kaemferol （2）, kampferol 3-O-β-D-glucoside （3）, quercetin （4） and tricin （5） , separately. Compound 1 is a new phenylpropionic acid derivatives. All compounds were obtained from this plant for the first time.
