title: [Determination of piperylpiperidine in wuwei qingzhuo powder by reversed phase HPLC].
abstract: A quantitative method has been developed for the determination of piperylpiperidine in Wuwei Qingzhuo powder by reversed phase HPLC. The average recovery is 102.0% (RSD = 0.46%) and lowest detection concentration 0.03 microgram/ml. The linear range of piperylpiperidine is 1.875-30 micrograms/ml, r = 0.9999.
