To find the identification method of seeds from different locations, we analyzed the SDS-PAGE electrophoretogram of Magnolia officinalis seeds from 5 different locations of Enshi district, Hubei province, the genuine producing area of M. officinalis, and compared band numbers, band intensity and protein molecular weight of different locations. The result showed that there were significant differences among seeds from different locations. 9 bands with the molecular weight about 80.34, 63.07, 56.48, 51.32, 40.64, 25.18, 22.63, 21.70, 18.14 kDa were involved in all seeds electrophoretograms and could be as standard bands of M. officinalis seeds. Seeds from Badong county, Jianshi county and Enshi city had their own special bands which were very different from other locations. So this electrophresis method can be applied to identify different locations of M. officinalis seeds.

Directive 2004/24/EC of the European Parliament and the Council entered into force on April 30th, 2004. After 7 years, there is no Chinese medicine to be registered successfully in European market as traditional herbal medicinal products. The thesis gives some ideas to tackle this problem. Procedure for the Preparation of Community Monographs for Traditional Herbal Medicinal Products (EMEA/HMPC/182320/2005) published by European Medicines Agency is an important guidance for traditional herbal products to enter European Community monographs. The thesis introduces and details the procedure as well as gives feasible suggestions about the procedure. It suggests that Chinese medicines enter European Community monographs first, and then apply the registration according to the directive 2004/24/EC. This is an easier access to European market.

This paper firstly introduces the concept, method and current research of molecular phylogeography and then discusses its application in the study of geoherbs. The relativity between three genetic differentiation patterns of plant inferred by molecular phylogeography (i.e. allopatric fragmentation, restricted gene flow with isolation by distance and range expansion) and the formation of genuine character is analysed. Molecular authentication of geoherbs based on molecular phylogeography has the advantage of former molecular identification at technology and knowing genetic differentiation of geoherbs. Using molecular phylogeography for study on changing history of geoherbs habitat is also explicated. The problem of germplasm degeneration in cultural geoherbs could be effectively resolved by molecular phylogeography method. The application of molecular phylogeography in these subjects opens up prospects for study on geoherbs by using the principle and method of molecular phylogeography.

OBJECTIVETo provide the basis for improving utilization of Artemisia annua germplasm resources and breeding variety, the interrelations between artemisinin content, artemisinin yield and agronomic traits of A. annua were studied.
METHODThe artemisinin content and each agronomic trait of 63 A. annua germplasm resources were measured by the visual observation and measurement methods. And the correlation analysis, regression analysis and path analysis were adopted.
RESULTThe result showed that there were significant differences in the artemisinin content and yield of 63 germplasm resources from the main production region of A. annua. Correlation analysis showed that there were significantly positive correlation between leaf weight and artemisinin yield with stem and branch characters, but there were negative correlation between artemisinin content with leaf characters of A. annua plant. The artemisinin content of A. annua increased with the increasing of primary branch number, bottom secondary branch number, and bottom stem diameter, etc. On the other hand, it decreased with the increasing of top secondary branch number, secondary leaf axis length, and bottom branch diameter, etc. The artemisinin yield of A. annua increased with the increasing of artemisinin content, leaf weight, and bottom secondary branch number, etc., and decreased with the increasing of bottom branch diameter, middle secondary branch number, and stem weight, etc. Path analysis showed that the primary branch number and bottom secondary branch number had a direct positive effect on the artemisinin content of A. annua. But the top secondary branch number had a direct negative effect on the artemisinin content of A. annua. The leaf weight and artemisinin content had a direct positive effect on the artemisinin yield and the ratio of leaf/stem, branch weight and stem weight had a direct negative effect.
CONCLUSIONOn the breeding A. annua variety, it can take into account both high leaf yield and high artemisinin content. And it was strongly recommend that the plant with moderate plant height and crown, shortness pinnae and secondary leaf axis, less middle and top secondary branch, strong stem, higher primary branch number and bottom secondary branch number, and higher ratio leaf/stem could be selected for breeding new varieties with high leaf yield and high artemisinin content.
