复叶耳蕨地上部分黄酮类化合物

 目的研究复叶耳蕨(Arachniodes exilis)地上部分的化学成分。方法利用硅胶、C₁₈反相硅胶、Sephadex LH-20凝胶等色谱技术对其提取物进行分离纯化,根据化合物的理化性质和光谱数据进行结构鉴定。结果分离得到6个黄酮类化合物,分别为:柚皮芸香苷(1),芒花苷(2),圣草次苷(3),木犀草素-7-O-芸香糖苷(4),5,7-二羟基色原酮-7-O-芸香糖苷(5)和5,7-二羟基色原酮(6)。结论化合物1~6均为首次从该种植物中分离得到。

Flavonoids from Aerial Parts of Arachniodes exilis

OBJECTIVE To research the chemical constituents of the aerial parts of Arachniodes exilis. METHODS The compounds were isolated by column chromotography with silica gel, C₁₈ reverse-phase silica gel, Sephadex LH-20, and their structures were elucidated on the basis of physiochemical propertities and spectral analysis. RESULTS Six compounds were isolated and identified as narirutin (1), miscanthoside (2), eriocitrin (3), lutinolin-7-O-rutinoside (4), 5,7-dihydroxychromone-7-O-rutinoside (5) and 5,7-dihydroxychromone (6), respectively. CONCLUSION All compounds were obtained from this plant for the first time.
