从香椿(Toona sinensis)根中分得两个新的柠檬苦素类化合物,TooninA(1)和B(2),以及一个新的二氢苯并呋喃去甲木脂素,TooninC(3)。(2′,4 ′-二羟基-6 ′-甲基苯基)-吡喃-2-酮(4),布曲替诺龙A(5),普鲁卡因酮(6),matairesinol(7),4-羟基-3-甲氧基苯-乙醇(8),胡萝卜酸(9)、异东莨菪内酯(10)、Lyoniresinol(11)、芦荟大黄素(12)和β-谷甾醇(13)。它们的结构进行了鉴定的基础上的一个和两个维度的光谱分析。化合物4、6-13为首次从该植物中分离得到。
Two new limonoids, toonins A (1) and B (2), and one new dihydrobenzofuran norlignan, toonin C (3), were isolated from the roots of Toona sinensis together with the ten known compounds 4-methoxy-6-(2′,4′-dihydroxy-6′-methylphenyl)-pyran-2-one (4), bourjotinolone A (5), proceranone (6), matairesinol (7), 4-hydroxy-3-methoxybenzene-ethanol (8), syringic acid (9), isoscopoletin (10), lyoniresinol (11), aloeemodin (12), and β-sitosterol (13). Their structures were elucidated on the basis of one- and two-dimensional spectroscopic analysis. Isolation of compounds 4, 6–13 from this plant is reported here for the first time.
