In order to assess the quality of the Chinese medicinal concentration preparations (CMCP), a continuous investigation plan has been initiated since 2007. In 2010, 52 samples including Sheau- Qing-Long-Tang, Buu-Jong-Yih-Chih-Tang and Ger-Gen-tang were collected from CMCP stores and pharmaceutical manufacturers by local health authorities. Based on the registered specifications, HPLC method was applied to determine the contents of marker constituents in these preparations. The results revealed that 8 (15.4%) samples were out of specifications. The report will be provided to the local health governments and the central authority for administrative reference.
