HPLC-MS Fingerprinting of Chinese Herbal Medicine
Scientists from Peking University Health Science Center (Beijing, China) and the University of Macau (Taipa, Macau, China) used high performance liquid chromatography (HPLC) with diode-array and mass spectrometry (MS) detection to distinguish between the crude herbs of four species of Herba Cistanche, a Chinese herbal medicine that has been recorded in the Chinese Pharmacopoeia.

In this “fingerprinting” method, 18 characteristic peaks were identified by comparing retention times with those of reference substances.
