Fingerprint of Lu’an Guapian tea based onhigh performance liquid chromatography

Using high performance liquid chromatography (HPLC) technology to study the fingerpingt of Lu’an Guapian. The result showed that:the main component could be separated well with acetonitrile and 0.03% three trifluoroacetic acid as the mobile phase, by the gradient elution method. The 12 samples of HPLC fingerprints showed that this method could identify a total of 16 chromatographic peaks as Lu’an Guapian tea fingerprint peaks. Then establish HPLC fingerprinting of Lu’an Guapian tea. Compared with two Huoshan Huangya samples, the result showed that the two HPLC maps of Huangya were much diffient from Lu’an Guanpian maps. And the different a reas of Lu’an Guapian teas HPLC chromatogram also exists some differences. The result showed the chromatogram could be used as the basis for the different origin of Guanpian tea, and also provided the experimental basis for the Lu’an Guapian quality control.
