用北柴胡根制备的柴胡注射液的含量测定方法,目前均用紫外分光光度计于276nm波长处测定其光密度值,并要求光密度值不低于0.45。而我厂生产的柴胡注射液,是以柴胡全草为原料,因此能否采用紫外分光光度法测定其含量,值得研究。为此作了以下实验,现将结果报道于下。 The method for determining the content of Bupleurum chinense prepared by using the Radix Bupleuri roots is currently determined by an ultraviolet spectrophotometer at a wavelength of 276 nm, and the optical density is required to be not lower than 0.45. The Bupleurum injection produced by our factory is based on Bupleurum chinense as raw material, so it is worth investigating whether it can be determined by ultraviolet spectrophotometry. The following experiments were carried out for this purpose, and the results are reported below.
