摘要
本文利用快速等浓度洗脱高效液相色谱技术,测定心肌组织中肌酸(Cr)、磷酸肌酸(PCr)、次黄嘌呤(Hypo)、尼克酰胺腺嘌呤二核营酸(NAD),腺苷一磷酸(AMP)、腺苷二磷酸(ADP)、腺苷三磷酸(ATP)和环一磷酸腺苷(cAMP),同时检测与能量代谢有关的标准物质色谱。检测结果表明,等浓度洗脱高效液相色谱技术,可测定与能量代谢有关的18种物质,其中八种物质可同时测定,此八种标准物质的重复性(CV%在0.97-3.78%)和回收率(88.1-117.6%),均符合方法学要求。因此,该技术是测定心肌等生物组织中能量物质的较理想方法。
To determine energy compounds in myocardial tissue simultaneously, we determined standard Creatine(Cr), Creatine phosphate(PCr), Hypoxanthine(Hypo), Nicotinamide adenine dinucleotide (NAD), Adenosine monophosphate (AMP), Adenosine diphosphate (ADP), Adenosine triphosphate (ATP), Cyclic-adenosine monophosphate(cAMP), and other compounds related to energy metabolism by a rapid isocratic method.The result showed that standard curves of the eight compounds were linear and passed through the origo for all examined concentrations (r=0.999).A recovery (88.1～117.6%) and replication (CV%=0.97～3.78%) for the present method was found to be accord with methology request.
