The raw material of paeoniflorin was examined for the preparation of the "Paeoniflorin Reference Standard". The analytical data obtained were: UV spectrum, lambda max, 231.9 nm; and specific absorbance (E(1 cm)1%) in methanol at 230 nm = 263.4 IR spectrum, specific absorptions of the raw material were consistent with those of the Paeoniflorin Reference Standard Standard (Control 012); High-performance liquid chromatography(HPLC), several impurities were detected. The total amount of impurities was 0.86%. Based on the above results, the candidate material was authorized as the Paeoniflorin Reference Standard (Control 021) of the National Institute of Health Sciences.
