Abstract

目的:研究毛萼紫薇(Lagerstroemia balansae Koehne)的化学成分。方法:采用各种色谱技术分离纯化化合物,并通过理化性质和波谱学方法鉴定化合物的结构。结果:从毛萼紫薇茎的95%乙醇提取物中分离得到7个化合物,分别鉴定为ficus-carpanoside A(Ⅰ)、反式-阿魏酸二十八烷酯(trans-ferulic acid octacosyl ester,Ⅱ)、lyoniside(Ⅲ)、gomisin N(Ⅳ)、正-三十烷醇(n-triacontanol,Ⅴ)、β-谷甾醇(β-sitosterol,Ⅵ)和胡萝卜苷(daucosterol,Ⅶ)。结论:以上化合物均为首次从该植物中获得,其中化合物ⅠⅤ为首次从紫薇属植物中分离得到。同时本实验还在2D-NMR的基础上对化合物Ⅰ在DMSO-d6中的1H-NMR和13C-NMR数据以及化合物Ⅰ在DMSO-d6中的1H-NMR数据进行了全归属,并纠正了文献中化合物Ⅲ13C-NMR数据的错误归属。 

OBJECTIVE: To study the chemical constituents of Lagerstroemia balansae Koehne. METHODS: The crude herb of the stems of L. balansae was extracted with 95% EtOH and isolated by repeated chromatographic methods. The structures of the isolated compounds were elucidated by physicochemical and spectral analysis. RESULTS: Seven compounds were yielded and identified as: ficuscarpanoside A(I), trans-ferulic acid octacosyl ester (II), lyoniside (III), gomisin N (IV), n-triacontanol (V), β-sitosterol (VI) and daucosterol (VII). CONCLUSION: All compounds were isolated from this plant for the first time, and compound (I-V) were obtained from the genus Lagerstroemia for the first time. On the basis of 2D-NMR spectra the 1H and 13C-NMR signals of I, the 1H-NMR signals of III in DMSO-d6 were assigned totally and the uncorrected assignment of 13C-NMR signals of III in the literature were revised.
