title: [Quantitative determination of three active ingredients for quality evaluation of Angelica dahurica].
abstract: A HPLC method has been developed in the current investigation for simultaneous determination of three chemical markers of by akangelicin, imperatorin and isoimperatorin in Radix Angelicae Dahuricae. Separation was performed at 30 degrees C. on achromatographic column of Platisil ODS C18 (4.6 mm x 250 mm, 5 μm). The mobile phase was acetonitrile-water. The flow rate was 1.0 mL x min(-1) and the detection wavelength was 254 nm. The results showed that the three chemical markers could be well resolved and that in the selected linear range, all calibration curves of the three chemical markers showed good linearity (R2 ≥ 0.999 8). The recoveries of byakangelicin, imperatorin and isoimperatorin were 100.83%, 100.10% and 103.52%, respectively, and RSD were 1.7%, 0.77% and 0.41% (n = 6), respectively. The data suggested that the developed HPLC method had good reproducibility, robustness, and accuracy, which was suitable for the quality control of Radix Angelicae Dahuricae. Applications of this method showed that the three chemical markers had higher contents in the Bozhou Anhui and Changge Henan than others.
