斜方复叶耳蕨的化学成分研究

目的:对斜方复叶耳蕨Arachniodes rhomboidea地上部分进行化学成分分离鉴定。方法:采用不同色谱技术进行分离,用波谱和化学方法确定化合物结构。结果:分离鉴定6个黄酮醇类化合物,分别为山柰酚(1)、山柰素-3-O-α-L-鼠李糖苷(2)、山柰素-3-O-β-D-葡萄糖苷(3)、山柰素-3,7-O-α-L-鼠李糖苷(4)、槲皮素-3-O-β-D-葡萄糖苷(5)、山柰素-3-O-β-D-芸香糖苷(6)。结论:所有化合物均为首次从该植物中得到。

Studies on chemical constituents of Arachniodes rhomboidea

OBJECTIVE: To study chemical constituents of Arachniodes rhomboidea. METHOD: Silica gel column chromatography and Sephadex LH -20 gel column chromatography were employed for the isolation and purification. The structures were identified on the basis of spectral data and chemical methods. RESULT: Six compounds were isolated and identified as follows: kaempferol (1), kaempferol-3-O-alpha-L-rhamnoside (2), kaempferol-3-O-beta-D-glucoside (3), kaempferol-3, 7-O-alpha-L-dirhamnoside (4), quercetin-3-O-beta-D-glucoside (5), kaempferol-3-O-beta-D-rutinoside (6). CONCLUSION: Compouds 1-6 were isolated from this plant for the first time.
