To investigate the chemical constituents of the roots of Flemingia philippinensis.
Silica gel, ODS silica gel and Sephadex LH-20 column chromatography were employed for the isolation and purification. The structures were identified on the basis of spectral data (MS, 1H-NMR and 13C-NMR) and chemical evidence.
Seven compounds were isolated from the 75% ethanolic extract of the roots of F. philippinensis and identified as follows: flemiphilippinin D (1), dorsmanins I (2), osajin (3), eriosematin (4), lupinalbin A (5), genistein (6) and 3'-O-methylorobol (7).
The compounds 2, 3 and 4 were isolated from the genus Flemingia for the first time. The compounds 2 and 4 were obtained from the Flemingia philippinensis for the first time.
研究菲律宾千斤拔根的化学成分。
采用硅胶柱色谱、ODS硅胶柱色谱和葡聚糖凝胶LH - 20柱色谱进行分离纯化。根据光谱数据（质谱、氢核磁共振谱和碳核磁共振谱）和化学证据鉴定结构。
从菲律宾千斤拔根的75%乙醇提取物中分离得到7个化合物，分别鉴定为：菲律宾千斤拔宁D（1）、多斯曼宁I（2）、奥沙金（3）、毛鱼藤素（4）、羽扇豆醇A（5）、染料木素（6）和3'-O-甲基奥洛波尔（7）。
化合物2、3和4首次从千斤拔属植物中分离得到。化合物2和4首次从菲律宾千斤拔中获得。
