目的:研究瘤果黑种草子的化学成分。方法:采用硅胶柱色谱进行分离纯化,根据理化性质和波谱分析鉴定化合物的结构。结果:从瘤果黑种草子中分离鉴定了9个化合物,分别为黑种草三糖(Ⅰ)、常春藤皂苷元3-O-α-L-鼠李糖基-(1→2)-α-L-吡喃阿拉伯糖苷(Ⅱ)、常春藤皂苷元3-O-β-吡喃木糖基-(1→3)-α-L-鼠李糖基-(1→2)-α-L-吡喃阿拉伯糖苷(Ⅲ)、蔗糖(Ⅳ)、硬脂酸(Ⅴ)、十六烷酸甘油酯(Ⅵ)、β-谷甾醇(Ⅶ)、胡萝卜苷(Ⅷ)、对羟基苯甲酸(Ⅸ)。结论:化合物Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅷ,Ⅸ首次从该植物中发现,其中化合物Ⅰ为新化合物。

Studies on chemical constituents in the seeds of Nigella glandulifera

OBJECTIVE: To investigate the chemical constituents in the seeds of Nigella glandulifera. METHOD: The chemical constituents were isolated and repeatedly purified on silica gel column. They were identified and structurally elucidated by means of physio-chemical constants and spectral analysis. RESULT: Nine compounds were identified as nigellamose (I), alpha-hederin (II), 3-O-beta-D-xylopyranosyl-(1-->3)-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinpyranosyl]-hederagenin (III), sucrose (IV), stearic acid (V), 1-O-hexadecanolenin (VI), beta-sitosterol (VII), daucosterol (VIII) and p-hydroxybenzoic acid (IX). CONCLUSION: I, II, III, VI, VIII and IX were obtained from the plant for the first time, and I is a new compound.
