滑桃树种壳化学成分的鉴定

摘要

Aim To study the chemical constituents of the seed crusts from Trewia nudiflora L.Method Five compounds were confirmed by the physical and chemical properties and the data of spectra.Result and conclusion The structures of the five compounds were isolated from the seed crusts of Trewia nudiflora and determined to be 2,3-dihydro-3,6,7-trihydroxy-1-H-benzo[b]pyran-4-one(1),α,2′,4,4′-tetrahydroxydidrochalaone(2),isoliquiritigenin(3),3-(3,4-dihydroxyphenyl)-prop-2-en-1-ol(4),β-sitosterol(5).Among those,compound 1 was determined to be a new compound,named nudiflone.Compound 3 showed antibacterial activity.%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(Trewia nudiflora L.)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.
