To study the chemical constituents of Amomum villosum.
Compounds were isolated from the alcoholic extract using polyamide, silica gel, Sephadex LH-20, ODS open column chromatography and other means. Their structures were elucidated according to spectral data and physiochemical properties.
Five compounds were isolated from Amomum villosum. They were identified as: 3-ethoxy-hydroxy benzoic acid (1), vanillic acid-1-beta-D-glucopyranosyl ester (2), isorhamnetin-3-beta-D-glucoside (3), flavanocoumarin (4), isoflavanocoumarin (5).
Compounds 1-5 are isolated from this plant for the first time.
研究阳春砂的化学成分。
采用聚酰胺、硅胶、葡聚糖凝胶LH-20、ODS开放柱色谱等方法从乙醇提取物中分离化合物。根据光谱数据和理化性质阐明其结构。
从阳春砂中分离得到5个化合物。它们分别被鉴定为：3-乙氧基-羟基苯甲酸（1）、香草酸-1-β-D-吡喃葡萄糖苷酯（2）、异鼠李素-3-β-D-葡萄糖苷（3）、黄烷香豆素（4）、异黄烷香豆素（5）。
化合物1-5首次从该植物中分离得到。
