Comparison analysis of different parts and geographical origins from southwestern China on artemisinComparison analysis of different parts and geographical origins from southwestern China on artemisinin content of Artemisia annua L

In the study we focus on determining the contents of artemisinin in Artemisia annua L. from different geographical origins of southwest district of China. The artemisinin contents of eleven samples are measured by the high performance liquid chromatography (HPLC). As a result, Artemisinin exists in different parts of A. annua plant and the content is as follow: inflorescences > leaves > stems. Except for the material from Qianjiang district, Artemisinin content of four materials in Chongqing area is higher than those of Sichuan and Guizhou by the average of 0.728%. We conclude that the artemisinin contents of A. annua, collected from Sichuan and Guizhou province, do not reach the value of industrial development, while the others can be exploited.
