Abstract:
OBJECTIVE: To establish methods for the identification of Rhizoma Chuanxiong and determination of Ferulic acid( FA) in Ganning granula. METHODS: The identification of Rhizoma Chuanxiong was carried out by TLC and the determination of FA was by performed by HPLC. FA was separated on Kromasil ODS-1 C18 column with water-methanol-acetic acid ( 30∶ 69. 5∶ 0. 5) as mobile phase. The detection wavelength was 322nm, the column temperature was set at room temperature and the flow rate was 1. 0mL? min-1. RESULTS: The TLC spots of the sample presented the same color as its counterparts of Rhizoma Chuanxiong standard and FA reference substance at the corresponding sites. The linear range of FA was 0. 010 12 ～ 0. 151 80? g( r=0. 999 9, n=8) . The average recovery was 97. 39% ( RSD=1. 97% ) . CONCLUSION: The methods of identification and content determination were rapid, accurate, specific and reproducible, and which are suitable for the quality control of Ganning granula.
