摘要(Abstract):

目的建立高效液相色谱-串联三重四级杆质谱法(HPLC-MS/MS)测定毛樱桃叶中槲皮苷、金丝桃苷、槲皮素、山奈酚、阿福豆苷、山奈酚-3-O-芸香糖苷和芦丁7种主要黄酮类化合物的含量。方法以Agilent ZORBAX SB-C18柱(150 mm×4.6 mm,5.0μm)为分析柱,以乙腈(A)和体积分数为0.1%的甲酸水溶液(B)为流动相体系,梯度洗脱,流速为0.8 m L·min~(-1)。采用电喷雾电离源(electrospray ionization,ESI)负离子化方式检测,以多重反应监测(multiple reaction monitoring,MRM)方式进行扫描定量。结果槲皮苷、金丝桃苷、槲皮素、山奈酚、阿福豆苷、山奈酚-3-O-芸香糖苷和芦丁分别在质量浓度为125~4 000、35~1 120、6.75~216、1.4~44.8、65~2 080、3.75~120、65~2 080μg·L-1内线性关系良好,相关系数(r)均大于0.999,7种成分的加样回收率为96.8%~103.4%(RSD<3%,n=6)。7种黄酮类化合物的含量质量分数分别为5.234%、0.203%、0.053%、0.005%、0.605%、0.011%、1.130%。结论该方法可用于测定樱桃叶中含量差异较大的黄酮类化合物的含量,为樱桃叶的质量控制提供参考依据。
Objective To determin the content of Qercetin-3-rhamnoside,Hyperoside,Quercetin,Kaempferol Kaempferol 3-O-rhamnoside,Kaempferol 3-rutinoside and Rutinum in the leaves of Cerasus tomentosa(Thunb.) Wall,by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).Methods The chromatographic separation was performed on an Agilent ZORBAX SB-C_(18) analytical column(150 mm×4.6 mm,5.0μm) using the mobile phases of acetonitrile(A) and 0.1%(V:V) formic acid aqueous solution(B) with gradient elution.The separated compounds were detected in multiple reaction monitoring(MRM) mode via negative electrospray ionization(ESI-).Results The linear ranges of Qercetin-3-rhamnoside,Hyperoside,Quercetin,Kaempferol,Kaempferol 3-O-rhamnoside,Kaempferol 3-rutinoside and Rutinum were 125-4 000,35-1 120,6.75-216,1.4-44.8,65-2 080μg·L~(-1),3.75-120,65-2 080μg·L~(-1),respectively.The extraction recoveries varied from 96.8%-103.4%(RSD <3%,n =6).The contents of these seven flavonoids in the leaves of Cerasus tomentosa(Thunb.) Wall,are 5.234%,0.203%,0.053%,0.005%,0.605%,0.011%,1.130%,respectively.Conclusions The developed method is simple,rapid good accurate and high sensitive,and is successfully utilized as a quality control method for leaves of Cerasus tomentosa(Thunb.) Wall..
