Eleven compounds were purified from the anti-inflammatory extract of Picris davurica by column chromatograph on HP20 macroporous resin, MCI, sephadex LH-20 and ODS.Their structures were determined by the spectra data of NMR and MS as isoestin 7-O-β-D-glucopyranosyl-2'-O-α-L-arabinopyranoside(1), isoetin-7-O-β-D-glucopyranosyl-2'-O-β-D-xyloypyranoside(2), isoetin-7-O-β-D-glucopyranosyl-2'-O-α-D-glucopy- ranoside(3), isoetin 5'-O-β-D-glucopyranoside(4), isoetin-2'-O-β-D-xyloypyranoside(5), isoetin-4'-O-β-D-O-β-D-glucopyranoside(6), isoetin-7-O-β-D-glucopyranoside(7), isoestin-2'-O-α-L-arabinopyranoside(8), luteolin-7-O-β-D-glucopyranosie(9), isoetin(10) and luteolin (11). All compounds were isolated from this plantfor the first time.Among them, compounds 1-8 were isolated from the genus Picris for the first time.
通过HP20大孔树脂、MCI、葡聚糖凝胶LH - 20和ODS柱色谱法从兴安漏芦的抗炎提取物中纯化出11种化合物。通过核磁共振（NMR）和质谱（MS）光谱数据确定它们的结构分别为异黄酮7 - O-β - D - 吡喃葡萄糖基 - 2'- O-α - L - 吡喃阿拉伯糖苷（1）、异黄酮7 - O-β - D - 吡喃葡萄糖基 - 2'- O-β - D - 吡喃木糖苷（2）、异黄酮7 - O-β - D - 吡喃葡萄糖基 - 2'- O-α - D - 吡喃葡萄糖苷（3）、异黄酮5'- O-β - D - 吡喃葡萄糖苷（4）、异黄酮2'- O-β - D - 吡喃木糖苷（5）、异黄酮4'- O-β - D - O-β - D - 吡喃葡萄糖苷（6）、异黄酮7 - O-β - D - 吡喃葡萄糖苷（7）、异黄酮2'- O-α - L - 吡喃阿拉伯糖苷（8）、木犀草素7 - O-β - D - 吡喃葡萄糖苷（9）、异黄酮（10）和木犀草素（11）。所有化合物均为首次从该植物中分离得到。其中，化合物1 - 8为首次从漏芦属植物中分离得到。
