目的:研究藏药脉花党参 Codonopsis nervosa ( Chipp.) Nannf.地上部分的化学成分。方法:采用 D101 大孔树脂柱、硅胶柱、ODS 柱、凝胶柱等色谱手段进行化学分离和纯化, 并利用各种波谱技术进行结构鉴定。结果:分离并鉴定了 15 个化合物, 分别为柯伊利素(1), 苜蓿素(2), 芹菜素(3), 琥珀酸(4), β-胡萝卜苷(5), 木犀草素(6), 木犀草素-7-O-β-D-葡萄糖苷(7),ethylsyringin (8), 芹菜素-7-O-β-D-葡萄糖苷(9), 木犀草素-7-O-β-D-葡萄糖基-(1→6)-[(6’’’-O-咖啡酸)-β-D-葡萄糖苷](10), 木犀草素-7-O-β-D-龙胆二糖苷(11), 丁香苷(12), 绿原酸(13), 新绿原酸(14), 对羟基苯甲酸葡萄糖苷(15)。结论:化合物 1 5, 8, 9, 12, 14,15 均首次从该植物中分离得到。
Objective: To study the chemical constituents in the aerial part of Codonopsis nervosa (Chipp.) Nannf. Methods: D101 macroporous resin column, silica gel column, ODS column, gel column and other chromatographic methods for chemical separation and purification, and the use of various spectroscopic techniques for structural identification. RESULTS: Fifteen compounds were isolated and identified as krelin (1), alfalfa (2), apigenin (3), succinic acid (4), β-daucosterol ), Luteolin-7-O-β-D-glucoside (7), ethylsyringin (8), apigenin-7-O- β -D- glucoside (9) β-D-glucosyl- (1 → 6) - [(6’’-O- caffeic acid) -β-D-glucoside] (10), luteolin-7-O-β-D- (11), syringin (12), chlorogenic acid (13), neogenic chlorogenic acid (14), glucoside p-hydroxybenzoate (15). Conclusion: Compounds 1 5, 8, 9, 12, 14 and 15 were isolated from this plant for the first time.
