|
|
To develop fundamental data of herbal materials with heat treatment, we studied analytical and extraction methods of benzopyrene in black ginseng and validated by HPLC analysis. Benzopyrene was successfully separated in mobile phase of acetonitrile:water (80 : 20) and detection of excitation 294 nm, emission 404 nm. The calibration curve of benzopyrene was linear over the concentration range of 1.17~37.50 ng/ml with correlation coefficient of above 0.999. The limit of detection (LOD) and quantitation (LOQ) of benzopyrene was 0.25 and 0.75 ng/ml, respectively. Hexane extraction method was used as a new extraction method for benzopyren and the efficient of extraction was over 95%. In conclusion, analytical method and extraction method were suitable for the determination of benzopyrene in the black ginseng and could be applied to fundamental study and guideline of herbal materials with heat treatment.
