A new di-C-prenylated coumarin, 7-methoxy-6,8-bis-(2,3-dihydroxy-3-methylbutyl)-coumarin (1), together with seven known compounds, isopimpinellin (2), an arylbenzofuran (3), three flavonoids (4-6), (+)-maackianin (7) and echinoisoflavanone (8), were isolated from the leaves of Sophora interrupta Bedd. The structure of the new compound 1 as well as known compounds was elucidated by extensive 1D and 2D NMR spectral studies.
从苦参(Sophora interrupta Bedd.)叶中分离得到一种新的二 - C - 异戊烯基香豆素,7 - 甲氧基 - 6,8 - 双 -(2,3 - 二羟基 - 3 - 甲基丁基)香豆素(1),以及七种已知化合物,异茴芹内酯(2)、一种芳基苯并呋喃(3)、三种黄酮类化合物(4 - 6)、(+) - 紫铆因(7)和棘豆异黄酮(8)。通过广泛的一维和二维核磁共振光谱研究阐明了新化合物1以及已知化合物的结构。
