中文摘要：

为研究樟属植物香樟树叶的化学成分,运用正相和反相硅胶柱层析、半制备型高效液相色谱法对樟树叶提取分离纯化,用波谱技术鉴定其结构.结果表明：从该植物中分离得到5个化合物,其中1个为木脂素类化合物,4个为黄酮苷类化合物,分别为（8R,8＇R）-3,3＇,4,4＇-四甲氧基-9-氧代-8-8＇,9-O-9＇-木脂素（I）,槲皮素-3-Ο-α-L-鼠李糖苷（II）,山奈酚-3-Ο-β-D-葡萄糖基（6→1）-α-L-鼠李糖苷（III）,芦丁（IV）,槲皮素-3-Ο-β-D-葡萄糖苷（V）.

英文摘要：

To study the chemical constituents of Cinamomum Camphora leaves, they were extracted isolated and purified by normal-phase and reverse-phase silica gel chromatography and semi-preparative high performance liquid chromatography and their structures were elucidated by spectral analysis. 5 compounds included 1 lignans and 4 flavonoid glycosides were obtained. They are （ 8R, 8＇R） -3,3＇,4,4＇-tetramethoxy-9-oxo-8-8＇,9-O-9＇-lignans （ I ） , Quercitin-3-O-a-L-rhamnoside （II） , Kaempferol-3-O-β-D-glueose（ 6---1 ） -a-L-rhamnoside（ III）, rutin（ IV）, Quercitin 3-O-β-D-glucoside （V） respectively.
