摘要
目的:研究凤尾草的化学成分。方法:通过硅胶柱色谱、硅胶薄层制备以及凝胶柱色谱的方法分离纯化化合物,利用质谱、核磁共振等现代波谱技术解析化合物结构。结果:从凤尾草(Pteris multifidaPolir.)甲醇提取物中分离得到7种化合物:经波谱鉴定为1个倍半萜苷:pterosin C 3-O-β-D-glucoside(1)和6个黄酮类化合物:芹菜素(2)、木犀草素(3)、芹菜素-7-O-β-D-葡萄糖苷(4)、芹菜素-7-O-β-D-葡萄糖-4′-O-α-L-鼠李糖苷(5)、芹菜素-4′-O-α-L-鼠李糖苷(6)、木犀草素-7-O-β-D-葡萄糖苷(7)。结论:化合物(2)、(3)和(5)、(6)为首次从该植物中分离得到。
Objective : To investigate the chemical constituents of Pteris multifida. Methods : All compounds were isolated and purified by normal column chromatography, paper thin layer chromatography and sephadex chromatography. The chemical structures were mainly elucidated by ESI mass and NMR spectra. Results:Seven compounds were isolated from the methanol extracts of Pteris multifida. In addition to a glycoside of sesquiterpene pterosin C-3-O-β-D-glucoside (1), six flavonoids were isolated from S. barbata asfouows : apigenin ( 2 ), luteolin ( 3 ), apigenin-7-O-β-D-glucoside ( 4 ), apigenin-7-O-β-D-glucosyl-4 ' -O-α-L-rhanrnoside ( 5 ), apigenin- 4' -O-α-L-rhanrnoside ( 6 ) and luteolin-7-O-β-D-glucoside (7). Conclusion : Compound ( 2 ), ( 3 ) and ( 5 ), ( 6 ) are isolated from Pteris multifida for the first time.
