摘要
目的建立同时测定金花葵药材中7种核苷类成分(尿嘧啶、胞苷、尿苷、腺嘌呤、鸟苷、腺苷、2’-脱氧腺苷)含量的高效液相色谱法(HPLC),并对金花葵药材进行质量关联分析与评价。方法采用HPLC-光电二级管阵列(PDA)法测定金花葵药材中7种核苷类成分,基于7个指标性成分含量及指标性成分加和含量对11批金花葵进行质量表征,并对表征结果进行关联性分析。结果7种核苷类成分线性关系良好,精密度、稳定性、重复性、加样回收率均符合方法学测定要求,并应用所建立的方法测定了11批金花葵药材中7种核苷类成分的含量;以批号1为基准药材,批号2、6、9、10、4各指标成分总体含量高于基准药材,批号6、9、8、4、3、11与基准药材关联性最高,综合评价得出批号1、2、6、9、4优良度居前。结论所建立的金花葵药材中核苷类成分的含量测定方法及质量表征关联分析模式能分析金花葵质量整体关联性与应用有效性,为金花葵药材的质量控制及评价提供了可靠依据。
Objective To establish a method of high performance liquid chromatography（ HPLC） for simultaneously determining of 7 nucleoside（ uracil,cytidine,uridine,adenine,guanosine,adenosine and 2＇-deoxyadenosine） in Aurea helianthus,and conduct the relevant analysis and review on quality of Aurea helianthus. Methods HPLC-PDA was applied for determining 7 nucleosides in Aurea helianthus.The quality representation of 11 batches of Aurea helianthus was carried out and representation results were given relevant analysis based on the content of index components and index component adducts from7 nucleosides. Results The linear relations of 7 nucleosides were good,and precision,stability,repeatability and sample recoveries were all accorded with the requirements of methodology determination.The content of 7 nucleosides in 11 batches of Aurea helianthus was determined by using the established method. Taking batch lot 1 of Aurea helianthus as criterion material,the content of index components was higher in batch lot 2,6,9,10 and 4,and relevancy was the highest among criterion Aurea helianthus and batch lot 6,9,8,4,3 and 11. The comprehensive review showed that excellent degrees of batch lot1,2,6,9 and 4 were in the lead. Conclusion The established method for determining content of nucleosides in Aurea helianthus and correlation analysis mode of quality representation can analyze overall quality relevancy and application validity,which provides the reliable evidence for quality control and review of Aurea helianthus.
