| 摘 要： | 本文报道从小叶黑柴胡(Bupleurum Smithii Wolff Var. Parvitolium Shanet Y. Li)分离出的一种新皂苷, 应用COSY, CH-COSY, TOCSY, HMQC-COSY, HMBC等NMR方法对其结构进行了研究, 确定该化合物为3β, 16β, 23, 28-四羟基齐墩果烷-11,13(18)-二烯-3-O-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖基-(1→6)-[β-D-吡喃葡萄糖基-(1→2)]-β-D-吡喃葡萄糖苷(1), 命名为柴胡皂苷O(Saikosaponin O)。

| Abstract: | Saikosaponin O was isolated from Bupleutum smithii Wolff var. parvifolium Shan et Y. Li. Its structure was determinated by NMR methods. From TOCSY and DQF-COSY spectra, the residues of monosaccharides and all their assignments were acquired. The anomeric configurations were obtained by ^3J~H~1~H~2. The HMQC-COSY spectrum was used successfully for ^1^3C assignment since it was difficult to do it only by CH-COSY spectrum. All the glucosidic linkages were obtained from HMBC spectrum based on the ^1H and ^1^3C assignments, NOESY spectrum also gave the concordant result about the configurations and the linkage positions. |
