中文摘要: |
目的:对在保健食品中发现的一种非法添加的西地那非衍生物进行确证。方法:采用高效液相色谱-二极管阵列检测器(HPLC-DAD)技术在日常检测保健食品非法添加时发现一种新型西地那非衍生物。经制备液相法分离纯化得到该化合物,采用高效液相色谱-二级质谱联用(LC-MS/MS)技术获得该化合物准分子离子和碎片离子,并进一步通过核磁共振氢谱确认,结合文献分析,最终确证该化合物。结果:该化合物分子式C23H30N6O3,分子量438,结构为去甲基卡波地那非。结论:去甲基卡波地那非在国内未被报道,是一种新型PDE-5抑制剂。 |

Objective: To confirm one kind of sildenafil derivatives illegally added in health foods. Methods: A novel sildenafil derivative was observed in a routine screening for compounds illegally added in heath foods by HPLC-DAD. The compound was purified by preparative HPLC. Its quasi-molecular ion and MS2 fragmentation spectrum were obtained by UPLC-MS/MS and was further confirmed by 1H-NMR. The structure of the compound was elucidated by analysis of these data and literature review. Results: The formula of this compound was C23H30N6O3 with molecular weight of 438, and the structure was Desmethyl Carbodenafil. Conclusion: Desmethyl Carbodenafil has not been reported in China yet and is a novel PDE-5 inhibitor. |
