中文摘要: 建立超高效液相色谱法(ultra performance liquid chromatography,UPLC)同时测定橘核中7 种成分(柚皮素、橙皮素、柚皮苷、橙皮苷、柠檬苦素、诺米林和黄柏酮)含量。采用UHPLC Polar-AQ-C18 色谱柱(2.1 nm×100 mm,1.8 μm),以乙腈(A)- 水(B)为流动相,流速 0.21 mL/min 进行梯度洗脱,柱温 30 ℃,检测波长为 283 nm(0~20 min)、210 nm(20 min~35 min)。结果显示,7 种成分均达到基线分离,各成分均有较宽的线性范围和良好的线性关系(r≥0.999 9),方法精密度、重复性、稳定性良好,平均加样回收率在102.62%~109.18%,相对标准偏差(relative standard deviation,RSD)均<2%。16 批橘核样品中7 种成分含量差异较大,其中柠檬苦素和诺米林的含量最高。
Abstract:To establish an ultra performance liquid chromatography(UPLC) method for the simultaneous determination of seven constituents(naringenin,hesperetin,naringin,hesperidin,limonin,nomilin,obakunone.)in Citri reticulatae semen.The separation was performed on a UHPLC Polar-AQ-C18(2.1 nm×100 mm,1.8 μm)was used as the stationary phase and the mobile phase consisted of acetonitrile(A)- water(B)with gradient elution at flow rate of 0.21 mL/min,the detection wavalength at 283 nm(0-20 min)and 210 nm(20 min-35 min),and the column temperature at 30 ℃.The results showed that the seven components reached baseline separation all the compounds had a wide linear range and good linearity(r≥0.999 9),with good precision,repeatability and stability.The average recoveries were between 102.62%-109.18%and the relative standard de-viation(RSD) were all less than 2%.The contents of seven components in 16 batches of Citri reticulatae semen were different and the contents of limonin and nomilin were the highest.
