摘 要:目的:对抗炎中药猴耳环的化学成分进行研究。方法:采用体外抗病毒活性追踪的方法,应用大孔吸附树脂吸附,聚酰胺、硅胶和凝胶柱色谱技术进行分离,根据理化性质和波谱数据鉴定其结构。结果:分离并鉴定了6个化合物:tricetiflavan(5,7,3′,4′,5′-pentahydroxylflavan)(1),myricitrin(myricetin-3-O-α-L-rhamnopyranoside)(2),quercitrin(quercetin-3-O-α-L-rhamnopyranoside)(3),quercetin(4),methyl gallate(5)和gallic acid(6)。结论:化合物1-5为首次从陔植物中分离得到,其中化合物4被发现有较好的体外抗呼吸道合胞病毒(RSV)活性。Objective: To study the antiviral constituents in the stems and leaves of Pithecellibium clypearia. Method: The constituents of P. clypearia were systematically separated with various chromatographic techniques in combination with antiviral activity monitoring. Their structures were elucidated by physical and chemical properties and spectral data. Result: Six compounds were isolated from P. clypearia and were identified as: tricetiflavan (5, 7, 3', 4', 5'-pentahydroxylflavan) (1), myricitrin (myricetin-3- O-α- L-rhamnopyranoside) (2), quercitrin (quercetin-3- O-α- L-rhamnopyranoside ) (3), quercetin (4), methyl gallate (5) and gallic acid (6).Conclusion: Compound 1 - 5 were obtained from this plant for the first time. Compound 4 was found to show an obvious anti-respiratory syncyfial virus (RSV) activity.
