目的研究滑桃树种壳中的化学成分。方法通过理化性质和光谱数据的分析鉴定了 5个化合物的结构。结果与结论从滑桃树 (TrewianudifloraL .)种壳中分离到 5个化合物。分别鉴定为 :2 ,3 二氢 3,6 ,7 三羟基 1 苯丙吡喃 4 酮(1)、α ,2′ ,4 ,4′ tetrahydroxydidrochalaone(2 )、isoliquiritigenin(3)、3,4 二羟基桂皮醛 (4 )和 β 谷甾醇 (5 ) ,其中化合物 1是新化合物。化合物 3具有一定的抗细菌活性 Objective To study the chemical constituents in the shell of the cherry tree. Methods The structures of five compounds were identified by physicochemical properties and spectral data analysis. RESULTS AND CONCLUSIONS Five compounds were isolated from the fruit shell of the Twig. They were identified as: 2,3 dihydro 3,6,7-trihydroxyl-phenylpyramidone(1), alpha,2’,4,4’ tetrahydroxydidrochalaone(2), isoliquiritigenin(3), 3,4 II Hydroxycinnamic aldehyde (4) and beta sitosterol (5), where compound 1 is a novel compound. Compound 3 has a certain antibacterial activity
