Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 1999, Volume: 24, Issue:1 To establish a reversed phase HPLC method for separation and determination of licochalcone A, ferulic acid, isoliquiritigenin and nobiletin in Pleurospermum hookeri var. thomsonii.. Using ODS column with methanol-water(containing 1% acetic acid)(73:27, 28:72, 59:41) and methanol-water(65:35) as the mobile phase, the flow rate was 1 ml/min, the column temperature was 35 degrees C and UV detection at 345, 320, 345, 332 nm, different extraction methods for the sample were compared.. The average recoveries were 99.45%, 98.13%, 97.81% and 96.58%, the relative standard deviations were 0.83%, 0.99%, 0.73% and 1.55%, and the contents were 0.728, 0.124, 0.0830 and 0.0237 mg/g..
