目的研究紫薇Lagerstroemia indica茎叶的化学成分。方法通过硅胶、凝胶等柱色谱及高效液相色谱分离,根据理化性质和核磁共振波谱对化合物进行结构鉴定。结果从紫薇茎叶乙醇提取物中分离得到5个化合物,分别鉴定为1,2-二(3-羟基-4-甲氧基苯基)-3-氧代丙醇乙酸酯(1)、morusinol(2)、neocyclomorusin(3)、(+)-表丁香树脂醇-4-O-β-D-吡喃葡萄糖苷(4)、yunnanensin A(5)。结论化合物为1个新化合物,命名为紫薇乙酸酯A,化合物~为首次从该植物中分离得到。
Objective To study the chemical composition of stems and leaves of Lagerstroemia indica. Methods The compounds were identified by silica gel, gel column chromatography and high performance liquid chromatography (HPLC). The structures of the compounds were identified by physicochemical and nuclear magnetic resonance spectroscopy. Results Five compounds were isolated from the ethanol extracts of Lagerstroemia japonica Thunbergii and identified as 1,2-bis (3-hydroxy-4-methoxyphenyl) -3-oxopropanol acetate morusinol (2), neocyclomorusin (3), (+) - syringaresinol-4-O-β-D-glucopyranoside (4), yunnanensin A (5). Conclusion The compound is a new compound, named Crape Myrtle Acetate A, which is isolated from this plant for the first time.
