目的:对草豆蔻(Alpinia katsumadai Hayata)正丁醇部位化学成分进行研究。方法:采用不同柱色谱技术进行分离,通过光谱和波谱分析鉴定化合物结构。结果:分离鉴定了10个化合物,其中5个为黄酮类化合物,5个为含氮化合物,分别为quercetin3-O-(2,6-di-O-rhamnopyranosylgalactopyranoside)(1),isorhamnetin3-O-(2,6-di-O-rhamnopyranosylga-lactopyranoside)(2),pinocembrin-3,7-di-β-D-glucoside(3),quercetin 3-O-robinobioside(4),儿茶素(5),腺苷(6),尿嘧啶(7),烟酸(8),次黄嘌呤(9),腺嘌呤(10)。结论:10个化合物均为首次从该植物中分离得到,其中化合物1-4,6-10为首次从山姜属植物中分离得到。 Objective: To study the chemical constituents of n-butanol in Alpinia katsumadai Hayata. Methods: Different column chromatographic techniques were used for the separation of compounds. The structures of the compounds were identified by spectroscopic and spectral analysis. Results: Ten compounds were isolated and identified. Among them, five were flavonoids and five were nitrogenous compounds, which were quercetin3-O- (2,6-di-O-rhamnopyranosylgalactopyranoside), isorhamnetin3-O- 2,6-di-O-rhamnopyranosylga-lactopyranoside (2), pinocembrin-3,7-di-β-D-glucoside (3), quercetin 3-O-robinobioside Adenosine (6), uracil (7), nicotinic acid (8), hypoxanthine (9), adenine (10). CONCLUSION: All the 10 compounds were isolated from this plant for the first time. Compounds 1-4,6-10 were isolated from the genus Ginger for the first time.
