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
