【摘要】 <正>丹参酮Ⅱ_A 是丹参有效成分之一,经体外抑菌实验,对人体结核杆菌 H₃₇R_V 菌株有较强的活性。我们通过加入稀土金属离子 Eu³⁺、Tb³⁺,研究稀土金属离子和丹参酮Ⅱ_A 形成配合物的结构, 探讨稀土金属离子和丹参酮Ⅱ_A 形成配合物的结构,探讨稀土金属离子和丹参酮Ⅱ_A 配合物的配合位点及配位机理。更多还原

【Abstract】 The nuclear magnetic resonance relaxation phenoenon is asnoiated with molecular motion.In recent years,we have studied the molecular structure by means of measuring the relaxation times.In this paper the interaction of tansinone Ⅱ_A with rare earth metalions Eu³⁺, Tb³⁺has been studied by several analytical techniques,including ¹H NMR T₁ ¹H NMR ¹³C NMR,ultraviolet spectra,and fluorescence spctra.The coordination mechanism,of tansinone Ⅱ_A with rare earth metal ions has been discussed.The experimental results showed that taninone Ⅱ_A with Eu³⁺、Th³⁺ions formed stable pentaatomic chelate ring.更多还原
