摘要 目的:建立HPLC波长切换法同时测定小儿鼻敏口服液中绿原酸、马钱苷、甘草苷、黄芩苷、哈巴俄苷、黄芩素、甘草酸、汉黄芩素、甘草次酸共9个成分的含量。方法:采用Insertsustain C_(18)色谱柱(250 mm×4.6 mm,5μm),以乙腈-甲醇-0.3%磷酸为流动相,进行梯度洗脱;流速为1.0 mL·min^(-1),柱温25℃,检测波长327 nm(0~15.5 min,检测绿原酸)、250 nm(15.5~23 min,检测马钱苷)、280 nm(23~41.5 min,检测甘草苷和黄芩苷)、245 nm(41.5~46 min,检测哈巴俄苷)、215 nm(46~50.5 min,检测黄芩素)、250 nm(50.5~53 min,检测甘草酸)、276 nm(53~72 min,检测汉黄芩素)、250 nm(72~80 min,检测甘草次酸)。结果:各待测组分分离度良好;绿原酸、马钱苷、甘草苷、黄芩苷、哈巴俄苷、黄芩素、甘草酸、汉黄芩素、甘草次酸9个成分的线性范围分别为1.408~140.8μg·mL^(-1)(r=0.999 9)、3.060~306.0μg·mL^(-1)(r=0.999 9)、1.984~198.4μg·mL^(-1)(r=0.999 9)、8.187~818.7μg·mL^(-1)(r=1.000 0)、5.146~514.6μg·mL^(-1)(r=0.999 9)、1.172~117.2μg·mL^(-1)(r=0.999 9)、3.318~331.8μg·mL^(-1)(r=0.999 9)、1.072~107.2μg·mL^(-1)(r=0.999 9)和2.121~212.1μg·mL^(-1)(r=0.999 8);加样回收率(n=6)分别为99.1%(RSD=1.7%)、98.7%(RSD=1.8%)、98.1%(RSD=2.5%)、100.2%(RSD=1.2%)、97.0%(RSD=2.2%)、99.2%(RSD=2.5%)、98.6%(RSD=1.9%)、99.1%(RSD=2.2%)、99.6%(RSD=2.6%)。3批中试样品中绿原酸、马钱苷、甘草苷、黄芩苷、哈巴俄苷、黄芩素、甘草酸、汉黄芩素、甘草次酸9个成分的含量范围依次为0.813~0.827、298~0.312、2.014~2.174、4.125~4.339、0.706~0.712、0.417~0.421、1.025~1.098、0.412~0.425和0.173~0.182 mg·mL^(-1)。结论:本试验建立的含量测定方法符合方法学验证要求,可用于小儿鼻敏口服液的9个指标性成分的同时测定。 Objective: To establish an HPLC with switching wavelength method for simultaneous determination of nine constituents ( chlorogenic acid, loganin, liquiritin, baicalin, harpagoside, baicalein, glycyrrhizic acid,wogonin, and carbenoxolone ) in Xiaoer Bimin oral liquid. Methods: The separation was performed on a Shimadzu Insertsustain-C18 (250 mm × 4.6 mm, 5 μm )column with the gradient elution of acetonitrile-methanol-0. 3% phosphoric acid solution in a gradient mode at the flow rate of 1.0 mL. min-1 . The column temperature was set at 25 ℃. The UV detection wavelength was set at 327 nm for chlorogenic acid in 0-15.5 min, 250 nm for loganin in 15.5-23 min, 280 nm for liquiritin and baicalin in 23-41.5 min, 245 nm for harpagoside in 41.5-46 min, 215 nm for baicalein in 46-50. 5 min, 250 nm for glycyrrhizic acid in 50.5-53 min, 276 nm for wogonin in 53-72 min, and 250 nm for carbenoxolone in 72-80 min, respectively. Results: Excellent chromatographic separation was achieved and the ranges for linear correlation of chlorogenicacid, loganin, liquiritin, baicalin, harpagoside, baicalein, glycyrrhizic acid, wogonin and carbenoxolone were 1.408-140.8 μg. mL-1 ( r=0.999 9 ), 3.060-306. 0 μg. mL-1 ( r=0.999 9 ), 1.984-198.4 μg. mL-1 ( r=0.999 9 ), 8.187-818.7 μg. mL-1 ( r=1.000 0 ), 5.146-514.6 μg. mL-1 ( r=0. 999 9 ), 1.172-117.2 μg. mL-1 ( r=0. 999 9 ),3. 318-331.8 μg. mL-1 ( r=0. 999 9 ), 1. 072-107.2 μg. mL-1 ( r=0. 999 9 ), and 2.121-212.1 μg. mL-1 ( r=0. 999 8 ), respectively. The average recoveries ( n=6 ) of the nine components were 99.1% ( RSD=1.7% ) , 98.7% ( RSD=1. 8% ) , 98.1% ( RSD=2.5% ) , 100.2% ( RSD=1.2% ), 97.0% ( RSD=2.2% ), 99.2% (RSD=2.5%) , 98.6%(RSD=1.9%) , 99.1%(RSD=2.2%) , and 99.6% ( RSD=2.6% ), respectively. The content ranges for three batches of samples of ehlorogenicacid, loganin, liquiritin, baicalin, harpagoside, baicalein, glycyrrhizic acid, wogonin and carbenoxolone were 0.813-0.827 mg. mL
