RESUMO
In order to confirm the tradition that bolting Saposhnikoviae Radix could not be used as medicine,the content of four chromone components in the cortex and wood of Saposhnikoviae Radix was analyzed by high performance liquid chromatography( HPLC),and the chemical fingerprints were established,12 common peaks were calibrated. The similarity analysis found that the similarity between batches was 0. 115-0. 995,it indicates that the cortex and wood of Saposhnikoviae Radix have certain differences. On this basis,systematic clustering analysis,principal component analysis and orthogonal partial least squares discriminant analysis were carried out with the content of four chromone components and whether they met the pharmacopoeia criteria as the original variables. The results showed that the content of the four components in the cortex of Saposhnikoviae Radix was much higher than that in the wood,and the four components detected were able to distinguish the cortex and the wood of Saposhnikoviae Radix. The results of the study reveal the tradition that bolting Saposhnikoviae Radix should not be used as medicine dut to decreased quality.

According to the meteorological index of the growth of Blumea balsamifera, and by using the climate and geographic date recorded in the main meteorological stations for 54 yearsï¼1960-2014ï¼ in Guizhou province, the authors established a regression model between climate division factors and geographic information for the possible planting area. Considering integrated various factors including climate factor, gradient and elevation, based on GIS technology, ascertain the planting area of B. balsamifera. Combined with the land use condition of Guizhou province based on RS, analyzed the distribution rule of the synthesis index, climatic divisions of B. balsamifera in Guizhou were divided into 3 areas (the most suitable, suitable, sub-suitable) objectively. There are 3 areas can plant B. balsamifera (the southwest, the south and the north). The most suitable climate area has 76.98 km², the suitable climate area has 156.04 km², and the sub-suitable climate area has 235.43 km².

This study was aimed to analyze the correlation between commercial specifications of Panacis Quinquefolii Radix and quantitative indexes of sevent kinds of ginsenosides (ginsenosides Rg¹, Re, Rb¹, Rc, Rb2, Rb3, Rd) contained in Panacis Quinquefolii Radix by using high performance liquid chromatography (HPLC), explore the correlation between the characteristics of the traditional Panacis Quinquefolii Radix specifications and modern chemical quantitative indicators, and provide a theoretical basis for the quality grade evaluation of Panacis Quinquefolii Radix. The HPLC fingerprint method was used to analyze 40 batches of Panacis Quinquefolii Radix. A total of 19 peaks were marked, and the similarity was above 0.900 for all samples. On this basis, processing methods, product specifications, contents of 7 components, and the total contents of ginsenoside Rg¹, Re and Rb¹ were used as the original variables for cluster analysis and principal component analysis. The results showed great correlation between the quality of Panacis Quinquefolii Radix and the information on their origins, but the difference was less with the characteristics of traditional commercial specifications, indicating some limitations in the division of commercial specifications of Panacis Quinquefolii Radix. The results revealed the intrinsic relationship between the product specifications, traditional qualitative indexes, and quantitative indexes of chemical components of Panacis Quinquefolii Radix, providing a new idea for the objective comprehensive evaluation of the quality of Panacis Quinquefolii Radix.

Through study on the correlation between Atractylodis macrocephala lactones ingredient content and topographic factors, we researched regionalization from topography of five main producing provinces of the country, in order to provide a scientific basis for A. macrocephala reasonable cultivation. By sampling from 40 origins of five main producing provinces of the country, the variation of A. macrocephala lactones ingredient content in different conditions of topographic factors and the effect of altitude, slope and aspect was analyzed by SPSS. Then according to the relationship between A. macrocephala lactones ingredient content and topographic factors, the ecological suitability regionalization was conducted by using ArcGIS based on topographic factors. It is suitable for growth of A. macrocephala in the hilly and mountainous areas of southern whose A. macrocephala lactones ingredient content is in high levels. It is unsuitable for growth of A. macrocephala in Northern plain areas, but we can cultivate A. macrocephala in the hilly and mountainous areas of Northern. The most suitable topographic condition for cultivation of A. macrocephala : altitude 200 meters above, slope 3.00-4.99 degrees.
