为了研究喜树碱的药理性质 ,用比导数荧光光谱和紫外吸收光谱法分析了喜树碱在不同 p H介质中的形态分布。结果表明 ,在体液介质 ( p H7.4)中 ,它主要以开环形式存在
In order to study the pharmacological properties of camptothecin, morphological distribution of camptothecin in different p H media was analyzed by using derivative fluorescence spectroscopy and ultraviolet absorption spectroscopy. The results show that it exists mainly in the open loop in the body fluid medium (p H7.4)
