摘要
从板栗树皮的乙酸乙酯萃取物中分离得到1个类柠檬素(板栗素A)、1个类黄酮(槲皮素)和1个香豆素(东莨菪素)。通过光谱数据(ESI-MS, 1H-NMR, 13C-NMR, DEPT, HMBC, HSQC v COSY)分析和与文献报道的比较证实了它们的结构。
Isolation and structure determination of compounds from ethyl acetate extract of Chukrasia tabularis
From an ethyl acetate extract of the barks of Chukrasia tabularis, three compounds including one limonoid (tabularisin A), one flavonoid (quercetin), and one coumarin (scopoletin) were isolated by chromatographic methods. Their structures were comfirmed by analysis of spectroscopic data (ESI-MS, 1H-NMR, 13C-NMR, DEPT, HMBC, HSQC và COSY) and by comparison with the literature reports.
