title: Application of microscopy in authentication of Chinese patent medicine--Bo Ying compound.
abstract: To establish a quality control method for the Chinese Patent Medicine (CPM)-Bo Ying Compound (BYC), a comparison study was carried out on it with microscopy. The micro-morphological characteristics of its 22 components in the CPM and in the crude constituents have been documented and compared with each other. Their corresponding features were described and documented with color digital micrographs, so as to authenticate the presence of genuine crude constituents in BYC. The results showed that almost all constituents of BYC are found within their representative fragments in the CPM except one (Borax) that could dissolve or merge with the other components. Also the study indicated that light microscopy, an easy and economical method, could be used for the identification of this kind of CPM that contains plant and animal materials without the specific characteristic chemical marker compounds.
