This study was aimed to evaluate the quality ofYuan-Hu Zhi-Tong (YHZT) tablet from different manufacturers by high performance liquid chromatography (HPLC) fingerprint. An HPLC method was developed to establish the fingerprint of 12 batches of YHZT from 10 manufacturers. The common peaks were confirmed by mass spectrometric analysis. Similarity analysis (SA), hierarchical cluster analysis (HCA) and principal component analysis (PCA) were applied to analyze the fingerprint chromatography. The results showed that there were 15 common peaks in which 12 components were from Corydalis Rhizoma and 3 from Radix Angelicae Dahuricae. The similar degrees of 12 batches of YHZT tablet were between 0.498 and 0.999. Based on the values, they could fall into three groups. The result of HCA showed that 12 batches of samples could be divided into 3 classes. The results of PCA indicated that the first three principal components (PCs) could represent the 15 common peaks. According to the scores of 3 PCs, 12 batches of samples could be divided into three categories. The classification result was mainly affected by the components of Corydalis Rhizoma. The classification results of three methods were basically the same. Based on the combination of three methods, 12 samples can be divided into three grades in the aspect of quality. It was concluded that the quality differences of YHZT tablet from different manufacturers were obvious. The combining application of three methods can be used in the evaluation on fingerprint of samples from different sources and influence factor analysis. It can be used as an effective method for quality evaluation.

This article was aimed to study pretreatment method of styrene type macroporous resin and its application in the industrial production. The organic residues and heavy metals of styrene type macroporous resin were detected respectively by gas chromatography and atomic absorption spectrophotometry before and after pretreatment to optimize the pretreatment process. The results showed that contents of organic residues and heavy metals of styrene type macroporous resin with the preferred method of pretreatment are in line with relevant regulations. It was concluded that this pretreatment method was simple and feasible, which is suitable to be applied in the industrial production.

This paper was aimed to study the genetic diversity and genetic relationship of germplasm resource of Lonicerae Japonicae Flos in order to provide references for its breeding. A total of 36 samples from 18 farm varieties and wild species, as well as related species of Lonicera japonica Thunb. from the main production areas were studied by ISSR-PCR markers. The Jaccard coefficient was worked out by NTSYS-pc software. And a cluster dendrogram of different samples was established based on unweighted pair-group method with arithmetic mean (UPGMA). The re-sults showed that 12 ISSR primers generated 129 loci of which 114 loci were polymorphic. The average percentage of polymorphic bands (PPB) is 88.37%. In the cluster dendrogram, different samples of Lonicera japonica are in the same group, which showed that it is a natural species; the wild sample is separated from the cultivated samples; the traditional type-Maohua is relative stable, but the type of Jizhuahua includes complicated varieties, and it has obvi-ous genetic variation; the new variety Jiufeng 1 has already distinct into one stable type. It was concluded that the ISSR method was suitable for germplasm identification, genetic diversity analysis of Lonicerae Japonicae Flos, thus providing a theoretical foundation for its cultivation and breeding.
