Résumé

AIM To establish the HPLC fingerprints of Kangfuxin Liquid (extract of Periplaneta americana L.) and to determine the contents of six constituents.METHODS The analysis of this drug was performed on a TOSOH TSK-GEL ODS column (250 mm × 4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-water (containing 0.07% acetic acid) flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 280 nm.RESULTS There were twenty-four common peaks in the fingerprints of ten batches of samples (Ⅰ-Ⅹ) with the similarities of 0.932-0.993 (except for sample Ⅰ).Uracil,hypoxanthine,xanthine,inosine,protocatechuic acid and Cyclo (Gly-Tyr) showed good linear relationships within the ranges of 3.460-173.0,3.960-198.0,3.596-179.8,1.338-66.9,3.672-183.6 and 3.552-177.6 μg/mL,whose average recoveries (RSDS) were99.8% (2.65%),98.0% (2.55%),99.7% (1.59%),100.7% (2.80%),102.0% (2.09%) and 99.6% (1.88%),respectively.CONCLUSION This accurate,stable and simple method can be used for the quality control of Kangfuxin Liquid.

Résumé

In order to find the cardiotonic constituents of lateral roots of Aconitum carmichaelii Debx., the investigation was carried out. Silica gel column chromatography, Sephadex LH-20, medium-pressure MCI and reverse phase ODS column chromatography were used to separate the 90% EtOH extract of the lateral roots of Aconitum carmichaelii Debx. The structures of the isolated compounds have been identified by chemical properties and spectroscopic analyses. Ten compounds were isolated and their structures were elucidated as benzoic acid-5-hydroxy-2-benzoyl-amino methyl ester (1), honokiol (2), pinoresinol (3), salicylic acid (4), p-hydroxy-cinnamic acid (5), songorine (6), karakoline (7), mesaconitine (8), hypaconitine (9) and 14-benzoylhypaconitine (10), separetely. Compound 1 is a new compound and its structure has been established by NMR, HR-ESI-MS, UV, IR and X-Ray. Compound 2-5 are isolated from the lateral roots of Aconitum carmichaelii Debx. for the first time.
