| 摘 要： | 从无柄新乌檀乙醇浸膏的正丁醇部位分离得到7个已知配糖体化合物，经波谱分析为：喹诺酸-3-O-β-D-葡萄吡喃糖基(28→1)-β-D-葡萄吡喃糖酯(1)，齐墩果酸-(28→1)-β-D-葡萄吡喃糖酯(2)，熊果酸-(28→1)-β-D-葡萄吡喃糖酯(3)，喹诺酸-3-O-β-D-葡萄吡喃糖基-(1→3)-6-去氧-β-葡萄吡喃糖苷(4)，齐墩果酸-3-O-β-D-吡喃木糖基-(1→2)-β-D-葡萄吡喃糖基-28-O-β-D-葡萄吡喃糖酯(5)，番木鳖甙(6)，7-甲氧基-龙胆苦甙(7)。这些化合物均为首次从该属中分离得到。 |

| Abstract: | Seven known conpoundls were isolated from the n-BuOH fraction of the stems of Neonauclea sessilifolia(Roxb.) Merr, and their structures were elucidated by means of spectroscopic method as quinovic acid-3-O-β-D-glucopyranosyl- (28--→1)-β-D-glucopyranosyl ester( 1 ), oleanolic acid- ( 28 → 1 )-β-D-glucopyranosyl ester(2), ursolicacid-(28→1)-β-D-glucopyranosyl ester(3), quinovic acid-3-O-β-D-glucopyranosyl( 1→3)-6-deoxy-β-glucopyranoside(4), oleanic acid-3-O-β-D-xylopyranosyl-( 1 → 2 )-β-D-glucopyranoside-28-O-β-D-glucopyranosyl ester ( 5 ), iridoidloganin(6), 7-methoxy-gentiopicroside(7). All of them were isolated from the genus for the first time. |
