ABSTRACT

Objective:

To develop an HPLC-DAD method for the simultaneous determination and comparative analysis on the contents of prim-O-glucosylcimifugin, 4′-O-β-D-glucosyl-5-O-methylvisamminol, cimifugin, sec-O-glucosylhamaudol, psoralen, imperatorin, bergapten, and xanthotoxin in the roots of Saposhnikovia divaricata from Longxi areas.

Methods:

The extracts were obtained by methanol reflux method and the contents of the eight compounds were determined by HPLC-DAD. The mobile phase, consisting of acetonitrile-water, was programmed for a gradient elution. The flow rate was 1.0 mL/min, the detection wavelength was 254 nm, and the column temperature was 25°C.

Results:

Excellent linearity with correlation coefficents (r) of 0.9992-0.9999 was obtained. The average recoveries of the eight compounds were 96.2%-104.1% and all RSD values were less than 3%. The contents of the four coumarins in the roots of S. divaricata were much less than those four chromones. The contents of the four coumarins in the roots of Carum carvi and Peucedahum ledebourielloides were more than those in S. divaricta, while no chromones were detected except sec-O-glucosylhamaudol in P. ledebourielloides.

Conclusion:

The method appears to be simple, accurate, and well reproducible, which could be used for the simultaneous determination of the above-mentioned eight compounds in S. divaricata. According to the above analysis, C. carvi and P. ledebourielloides could not be used as the succedaneum of S. divaricata on the basis of the eight compound contents.
