【摘要】:目的建立L-02細胞中3-羥基-3-甲基戊二酰輔酶A(HMG-Co A)還原酶活性的檢測方法。方法色譜柱:C18色譜柱,流動相:甲醇-水(20μmol·L-1磷酸二氫鉀,p H 7.2)=6∶94,檢測波長:340 nm,柱溫:25℃,流速:1m L·min-1。考察該方法的專屬性、標(biāo)準(zhǔn)曲線和定量下限、精密度與回收率、穩(wěn)定性。結(jié)果還原型輔酶Ⅱ線性范圍為2.5~1000μmol·L-1,定量下限為0.5μmol·L-1,日內(nèi)、日間RSD分別在(5~6)%和(4~8)%內(nèi),相對回收率在(96.97~99.57)%內(nèi)。結(jié)論建立的L-02細胞中HMG-Co A還原酶活性檢測方法符合實驗要求,且可用于測定氟伐他汀對L-02細胞HMG-Co A還原酶活性的抑制作用。
