作者通过测定红花注射液的紫外吸收曲线,发现在波长267±1nm处有一最大吸收峰,其吸收度的大小与注射液对抗ADP诱导家兔血小板聚集的能力是相平行的。因此,认为测定吸收度的大小即可作为控制红花注射液内在质量的指标,从而为制订质量标准提供依据。在波长267±1nm处最大吸收的成分即为注射液在纸层析谱上的黄色部分(斑点2),因而,该黄色部分即为注射液的有效成分,也是注射液的主要成分。鉴于该黄色部分的紫外吸收特征及理化性质,认为该黄色部分不符合查耳酮结构,而与黄酮或黄酮醇结构较为吻合。
By measuring the UV absorption curve of safflower injection, the authors found that there is a maximum absorption peak at the wavelength of 267±1 nm, and the degree of absorption is parallel to the injection’s ability to fight ADP-induced platelet aggregation in rabbits. Therefore, it is considered that the determination of the degree of absorption can be used as an indicator to control the intrinsic quality of safflower injection, thus providing a basis for formulating quality standards. The component that absorbs at the wavelength of 267±1 nm is the yellow part (spot 2) of the injection in the paper chromatogram. Therefore, the yellow part is the active component of the injection and is also the main component of the injection. In view of the ultraviolet absorption characteristics and physicochemical properties of the yellow part, it is considered that the yellow part does not conform to the chalcones structure, but is more consistent with the structure of flavonoids or flavonols.
