Quality Evaluation of Rhodiola crenulata: Quantitative and Qualitative Analysis of Ten Main Components by HPLC

Abstract
A high performance liquid chromatographic method has been performed for the simultaneous identification and quantification of ten bioactive components in three botanical materials of Rhodiola genus (R. crenulata, R. sachliensis and R. dumulos). Eight samples of Rhodiola genus prepared from three different botanical materials were investigated by the proposed method, and the variance was revealed by the calculated results of these contents and similarity values for ten main flavonoids. The proposed method is simple, effective, and suitable for the evaluation of this traditional Chinese medicine.
