To investigate the chemical constituents of Pteris multifida.
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.
Seven compounds were isolated from the methanol extracts of Pteris multifida. In addition to a glycoside of sesquiterpene pterosin C-3-O-beta-D-glucoside(1), six flavonoids were isolated from S. barbata as fouows: apigenin(2), luteolin(3), apigenin-7-O-beta-D-glucoside(4), apigenin-7-O-beta-D-glucosyl-4'-O-alpha-L-rhanrnoside(5), apigenin-4'-O-alpha-L-rhanrnoside(6) and luteolin-7-O-beta-D-glucoside(7).
Compound(2), (3) and (5), (6) are isolated from Pteris multifida for the first time.
研究多裂凤尾蕨的化学成分。
所有化合物通过正相柱色谱、纸薄层色谱和葡聚糖凝胶色谱进行分离和纯化。化学结构主要通过电喷雾质谱和核磁共振光谱进行阐明。
从多裂凤尾蕨的甲醇提取物中分离出7种化合物。除了一种倍半萜类化合物蕨素C-3-O-β-D-葡萄糖苷（1）外，还从多裂凤尾蕨中分离出6种黄酮类化合物，如下所示：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-葡萄糖基-4'-O-α-L-鼠李糖苷（5）、芹菜素-4'-O-α-L-鼠李糖苷（6）和木犀草素-7-O-β-D-葡萄糖苷（7）。
化合物（2）、（3）以及（5）、（6）首次从多裂凤尾蕨中分离得到。
