compositions and acetylcholinesterase (AChE) inhibitory activitiy of the volatile oil from the bark of Peltophorum dasyrachis Kurz ex Bakar (yellow batai) were evaluated. As a result, 68 compounds, accounting for 88.0% of the total oil, were identified. The main characteristic constituent in P. dasyrachis was isolated by silica gel column chromatography and found to be a sesquiterpenoid, (+)-(S)-ar-turmerone
在这项研究中,评估了来自Peltophorum dasyrachis Kurz ex Bakar(黄色batai)皮中的挥发油的化学成分和乙酰胆碱酯酶(AChE)抑制活性。结果,鉴定出68种化合物,占总油量的88.0%。在主特征性的构成P. dasyrachis物通过硅胶柱色谱法分离并发现是倍半萜,(+) - (小号) -芳-turmerone(1)。在AChE抑制试验中,挥发油显示出有效的抑制活性,IC 50值为83.2±2.8μg/ mL。在挥发油成分和特征倍半萜中,(+)-(S)-ar-turmerone(1)和(+) - (小号)二氢AR -turmerone(2)是有效的化合物,以剂量依赖的方式抑制乙酰胆碱酯酶,用IC 50倍分别为191.1±0.3和81.5±0.2的值μM, 。(+) - (小号)二氢AR -turmerone(2),特别是,被认为是最有效的乙酰胆碱酯酶抑制剂
