摘要: 目的 建立同时测定犬血浆中槲皮素、山萘酚和异鼠李素浓度的HPLC-MS/MS 方法。方法 血浆样品经酸水解后用乙醚提取, 采用选择性反应检测方法测定其血药浓度。仪器为FinniganLC-MS/MS 二级四极杆质谱检测器, 色谱柱为Luna C18 (150 mm ×2.00 mm i.d., 5 μm, Luna,USA);流动相为乙腈-0.1 %甲酸, 梯度洗脱。结果 槲皮素、山萘酚和异鼠李素的线性范围均为0.5 ~ 100.0 ng/mL, 三种黄酮的最低定量限均为0.5 ng/mL, 各自日内日间精密度分别小于7.3 %,6.2 %和6.4 %, 回收率分别大于70 %, 66 %和70 %。结论 该测定方法经验证符合血浆样品的测定要求, 可以应用于临床前药代动力学研究。

Abstract: AIM: A rapid, sensitive and highly selective liquid chromatography-tandem mass spectrometry method was developed and validated for simultaneous determination of quercetin, kaempferol and isorhamnetin in dog plasma.METHODS: Quercetin, kaempferol and isorhamnetin conjugates were hydrolysed chemically.The analytes were extracted from plasma samples by liquid-liquid extraction, separated on a Luna ODS-2 column (150 mm ×2.1 mm I.D., 5 μm particle size), and detected by tandem mass spectrometry with a Finnigan IonSpray ionization interface. The mobile phase consisted of 0.1 % aqueous formic acid (A)and gradient-grade acetonitrile (B).RESULTS: The calibration curves for quercetin, kaempferol and isorhamnetin were linear in concentration ranges of 0.5-100.0 ng/mL in dog plasma.The method has a lower limit of quantification (LLOQ)of 0.5 ng/mL for all the three flavonols.The intra-and inter-day precisions, expressed as the R.S.D., were less than 7.3 %, 6.2 % and 6.4 % for quercetin, kaempferol and isorhamnetin, respectively, and the recovery was more than 70 %, 66 %and 70 %, respectively.The application of this assay was examined in a preliminary pharmacokinetic study of quercetin, kaempferol and isorhamnetin in beagle dogs after oral administration of 6 Ginkgo biloba tablets.CONCLUSION: The present method was suitable for determining quetcetin, kaempferol and isorhamnetin in dog plasma.
