目的对枳实的化学成分进行研究。方法采用色谱技术进行分离,应用波谱技术和化学手段,对分离得到的化合物进行结构鉴定。结果自枳实乙醇提取物中分离得到4个化合物,分别为3,5-二羟基苯基1-O-(6′-O-阿魏酰基)-β-D-吡喃葡萄糖苷[3,5-dihydroxyphenyl1-O-(6′-O-trans-feruloyl)-β-D-glucopyranoside,]、橙皮素(hesperetin,)、4′,5,7,8-四甲氧基黄酮(4′,5,7,8-tetramethoxyflavone,)及柠檬苦素(limonin,)。结论化合物为新化合物。

Objective To study the bioactive constituents of the immature fruits of Citrus aurantium. Methods Silica gel and Sephadex LH-20 were used to isolate the constituents of this plant. The spectroscopic Methods were applied for their structural elucidation. Results Four compounds were isolated from the ethanol extract of the immature fruits of C. aurantium. These compounds were elucidated as 3, 5-dihydroxyphenyl 1-O-(6′-O-trans-feruloyl)-β-D-glucopyranoside (Ⅰ), hesperetin (Ⅱ), 4′, 5, 7, 8-tetra- methoxyflavone (Ⅲ), and limonin (Ⅳ). Conclusion Compound Ⅰ is a new phenolic glycoside.
