From the stem of Derris ovalifolia, a new chromanone alkaloid characterised as 7-methoxy-3-[1-(3-pyridyl)methylidene]-4-chromanone (1) was isolated along with four known compounds, dehydrotoxicarol (2), dehydrodeguelin (3), toxicarol isoflavone (4) and indole-3-carbaldehyde (5). Their structures were determined on the basis of spectral data interpretation. The structure of compound 1 has also been confirmed by synthesis.
从黄桐属植物椭圆叶黄檀的茎中，分离得到一个新的色酮生物碱，被鉴定为 7-甲氧基-3-[1-(3-吡啶基)亚甲基]-4-色酮（1），此外还分离得到四个已知化合物，去氢毒豆醇（2）、去氢去钩藤碱（3）、毒豆异黄酮（4）和吲哚-3-甲醛（5）。根据光谱数据解析，确定了它们的结构。化合物 1 的结构也通过合成得到了证实。
