摘要
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ficuscarpanoside 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Ⅰ~Ⅴ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Ⅲ 13C-NMR数据的错误归属。
Abstract
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.
