In order to control the silver content in the preparation process of platinum group anti-cancer drugs, we put two kinds of color reagent to color in the production process of the platinum anti-cancer drugs by UV spectra measurement to control drugs production of platinum anticancer, thus we could control the silver content in the drugs so that it meets the pharmacopoeia standards of US and European 相似文献

Purpose: To establish a HPLC testing method of the content of bulk picoplatin and its impurities. Method: the separation was perform on a C18 column(4.6 mm×250 mm, 5 m) with potassium dihydrogen phosphate-aceton-itrile as the mobile phase at a flow rate of 1.0 mL/min. The detecting wavelength was set at 210 nm, and the column temperature was set at 30℃. Result: in the method validation, the linear relationship modulus of picoplatin is 0.9999, the systemic precision is 0.44%, the method precision is 0.74%, the average recovery rate is 99.62%, the LOD and LOQ of picoplatin is 0.2 ng and 1.0 ng. The average resolution of picoplatin and its impurities is more than 2. Conclusion: The established method is good specificity, high sensitivity, and good repeatability which could provide scientific evidence for the quality control of picoplatin and its impurities. 相似文献

采用循环伏安法(CV)和差分脉冲伏安法(DPV),研究了卡铂在多壁碳纳米管玻碳电极(MWCNTs/GCE)上的电化学行为并建立了卡铂的测定方法。结果表明:卡铂在多壁碳纳米管玻碳电极上有一对氧化还原峰,氧化峰电位Epa与还原峰电位Epc分别为0.73 V、0.26 V,峰电位之差为ΔE=0.47 V,Ipa/Ipc=1.57。在优化条件下,卡铂的氧化峰电流与其浓度在0.22~0.67 mmol/L范围内成良好的线性关系(r=0.9942),检出限为0.2 mmol/L。方法操作简便,准确可靠、灵敏度高,可用于卡铂含量的直接测定。 相似文献
