ABSTRACT
With the development and change of Uygur medicine, The sources,medicinal parts and producing area of some Uygur Medicine have changed. It is more important to master the classification, distribution and change of Uygur medicinal materials. These were more than 1 200 kinds Uygur medicine in history were resaerched by field investigation, philological research, and textual research, which main source of original plant were 140 families, 510 genera, 840 species; and source of original animal were 76 families, 107 genera, the original animal 141 species; 55 kinds of original mineral, which main producer were Xinjiang and Central Asia, West Asia, the Mediterranean, and North Africa, Southeast Asia and other provinces in China, there are individual medicinal materials from the Americas, Europe and other places. Through this study the classification, distribution, source and evolution of specific families and genera of Uygur medicine resources have mastered.It is hoped to provide theoretical basis for further research and development of Uygur medicinal materials.

Phytoremediation combined with suitable microorganisms and biodegradable chelating agents can be a means of reclaiming lands contaminated by toxic heavy metals. We investigated the ability of a lead- and cadmium-resistant bacterial strain (JB12) and the biodegradable chelator ethylenediamine-N,N'-disuccinic acid (EDDS) to improve absorption of these metals from soil by tall fescue and red clover. Strain JB12 was isolated from contaminated soil samples, analysed for lead and cadmium resistance, and identified as Burkholderia cepacia. Tall fescue and red clover were grown in pots to which we added JB12, (S,S)-EDDS, combined JB12 and EDDS, or water only. Compared with untreated plants, the biomass of plants treated with JB12 was significantly increased. Concentrations of lead and cadmium in JB12-treated plants increased significantly, with few exceptions. Plants treated with EDDS responded variably, but in those treated with combined EDDS and JB12, heavy metal concentrations increased significantly in tall fescue and in the aboveground parts of red clover. We conclude that JB12 is resistant to lead and cadmium. Its application to the soil improved the net uptake of these heavy metals by experimental plants. The potential for viable phytoremediation of lead- and cadmium-polluted soils with tall fescue and red clover combined with JB12 was further enhanced by the addition of EDDS.
