    Hong Wang is an associate professor of Department of Natural Medicine, School of Pharmacy, Peking University, Beijing. Her research interests include active components in medicinal plants and quality evaluation system of traditional Chinese medicine. She has undertaken many scientific research projects of Ministry of Education of the People's Republic of China, National Major Scientific and Technological Special Project for "Significant New Drugs Development" during the Twelfth Five-year Plan Period, National Administration of Traditional Chinese Medicine and Chinese Pharmacopoeia Commission. She also won the Second Prize of the State Scientific and Technological Progress Award and the third prize of Beijing Science and technology Progress Award. She made a systematic study on the resources and quality standards of many kinds of TCMs, including Rubiae Radix Et Rhizoma, Magnoliae Officinalis Cortex, Pyrrosiae Folium, Mume Flos, Polyporus and Apocyni veneti Folium. The results of her researches were presented in the Chinese Pharmacopoeia or in the industry standard and applied in practice.

Abstract:

To evaluate the quality of Polyporus umbellatus, we established a simple, repeatable and reliable method based on high performance liquid chromatography (HPLC) for specific chromatogram and fingerprint analysis, which was applied to analyze samples of medicinal materials and decoction pieces collected from different regions. Finally, ten characteristic peaks were designated in the specific chromatograms and applied to the authenticate identification of P. umbellatus samples. Nine common peaks were designated in the fingerprints, and then the similarities between 32 batches of samples were calculated. Among them, eight compounds were identified by HPLC-APCI-IT-TOF-MSn, four of which were identified in specific chromatograms and four in fingerprints. In the present study, we, for the first time, combined HPLC specific chromatograms and fingerprints for the species identification and quality evaluation of P. umbellatus. Collectively, our findings provided a new method for establishing a comprehensive quality standard of P. umbellatus.
