[Materia medica illustrations related to the regional names in Shandong province in Ben Cao Tu Jing].

Ben Cao Tu Jing had 48 materia medica illustrations related to the regional names in Shandong province. It was found that 42 of them were plant medicinal materials, distributed in seven areas in Shandong province. This study examined these illustration of plant medicinal materials and found that 26 species of these illustration of plant medicinal materials were identified with three genera and 11 illustrations were unverified. Most materia medica illustrations relating to the regional names in Shandong province were found mainly in Yanzhou, Qizhou and Zizhou. This indicated that materia medica were widely used in these areas in the Northern Song Dynasty. The haustorium of Cuscuta Chinensis were depicted in the "Shanzhou Tu Si Zi" and the habitat of wild poriacocos was described. This showed that the illustrators of Ben Cao Tu Jing might have conducted fieldwork and reflected on the main principles about how to identify materia medica in Ben Cao Tu Jing Zou Chi. Inconsistencies were found between the illustrations and the expressions of plant medicinal materials in some illustrations, such as Gui Jiu, Ginsen and Shan Zhu Yu. This suggested that in the Northern Song Dynasty Stemmacantha Uniflora, Belamcanda chinensis might have been mixed up with Dysosma and Pinellia Pedatisecta might have been mixed up with Pinellia Ternata. This was in line with the compiling theories of Su Song that they could be recorded together when the illustrations and literature were inconsistent with each other.

[Materia medica illustrations related to the regional names in Zhejiang province in Ben Cao Tu Jing].

Ben Cao Tu Jing had 38 materia medica illustrations related to the regional names in Zhejiang province. It was found that 30 of them were identified as being named after regional names in Zhejiang province, involving 20 families and 29 genera. One of the 38 materia medica illustrations was mineral medicine and seven of them were unverified. The twenty-five of these materia medica illustrations with regional names were found to be consistent with their names used today. Five of them came from similar names in Zhejiang province in the Northern Song Dynasty, another five of the 25 names were known with the names but not entity for the lack of full descriptions and drawings. It was found that the drawing and the text of "Ming Zhou Huang Yao" and "Qin Zhou Hong Yao" in Ben Cao Tu Jing were reversed. By comparing the materia medica illustrations related to regional names in Da Guan Ben Cao by Liu Jia and Zheng He Ben Cao by Zhang Huicun, the name and the illustration of "Jin Zhou Bei Mu" in Zheng He Ben Cao by Zhang Huicun was more believable than "Yue Zhou Bei Mu" in Da Guan Ben Cao by Liu Jia. "Tai Zhou Wu Yao" and "Zhe Ba Wei", as genuine medicinal materials in Zhejiang, can be traced back to the illustrations of "Tai Zhou Wu Yao", "Yue Zhou Bai Zhu", "Mu Zhou Mai Dong", "Wen Zhou Peng 'e Shu", "Yue Zhou Bei Mu" and "Tian Tai Wu Yao" in Ben Cao Tu Jing. These findings provided text and drawing literature of herbs in the Song Dynasty for the research of genuine medicinal materials and their characteristics in Zhejiang province. They also showed that the utilization and development of the resources of traditional Chinese medicine in Zhejiang in the Northern Song Dynasty mainly focused on the coastal areas.

[Types of medicine paintings in herbaceous and woody medicines in Ben Cao Tu Jing].

A total of 568 paintings of herbaceous plants and woody plants as medicine were involved in Ben Cao Tu Jing, accounting for 60% of the total drug illustrations and 76% of the botanical medicine paintings. These medicinal paintings can be classified into four types: original plant paintings, medicinal material paintings, plant and medicinal material paintings, and plant and their habitat paintings. The original plant paintings can be specifically divided into five sections: the whole plant paintings with roots, partial aerial part paintings with roots, plant paintings with ground lines, rootless plant paintings, and broken branch paintings. Among them, the drawings of " the broken branch paintings " and " the whole plant paintings with roots " are consistent with the basic principles of collecting plant specimens. Additionally, "the plant and medicinal material paintings " and "the medicinal material paintings "reflect that they were drawn based on the market survey of medicinal materials or collected medicinal materials specimens. These medicine painting demonstrate rich characteristics of medicinal plants and medicinal materials and a high artistic quality with realistic details.These paintings in Ben Cao Tu Jing echoes Tu Jing, combine the art of painting with the cognition ofnatural science, as the rudiment of early paintings of plant science.

[Textual research on Fengqing Jixueteng (Kadsura interior A. C. Smith), Kunming Jixueteng (Millettia dielsiana Harms ex Diels) and Jixueteng (Spatholobus suberectus Dunn)].

Being a common materia medica, the confusion of Jixuetengcaused by the homonyms of different substances for Jixuetengis always very complicated. Fengqing JixuetengPaste was first created in the Qing Dynasty. Fengqing Jixuetengwas derived from the dried stems of a variety of species in KadsuraJuss. and SchisandraMichx. from Schisandracea; while Kunming Jixueteng, derived from the dried stem of Millettia dielsianaHarms ex Diels, was firstly recorded in the Zhi wu ming shi tu kao(Textual Research on Reality and Titles of Plants). The earliest records of Spatholobus suberectusDunn as the original plant of Jixuetengwas in Guang xi ben cao xuan bian(Selected Compilation of Chinese Materia Medica in Guangxi). It was not until 1997 that Spatholobus suberectusDunn was recorded as an origin of orthodox product of Jixuetengin the Chinese Pharmacopoeia. At present, the origins of Jixuetengis very complicated as recorded in different provincial standards, including three species of three genus from Leguminosae.The varieties of species from KadsuraJuss. and SchisandraMichx. had long been used as Fengqing Jixueteng, but currently the most extensively used one is Spatholobus suberectusDunn as Jixueteng. There are more differences in records of Jixuetengin history up to the present, hence, further investigation and research on Jixuetengis still necessary.
