Determination of Pentachloronitrobenzene in Panax Ginseng by HPLC
The separation and determination of pentachloronitrobenzene powder within 10 min by HPLC with HP hypersil C18 column (4.6 mm × 250 mm), isocratic mobile phase of 0.05 mL/L disodium hydrogen phosphate and acetonitrile (35:65, v/v) containing 0.3 mL/L triethylamine at pH 6.2 and UV detector at 254 nm are described. The method is simple, rapid, sensitive and accurate. The intra-day and inter-day precision and accuracy, quantification limits and extraction yields are calculated for pentachloronitrobenzene at the sametime.
