Objective: To analyze correlation of quality and cadmium content in Chuanxiong Rhizoma herb and its germplasm

in order to provide a scientific basis for breeding of this herb and solving its problem of cadmium content exceeds bid. Method: Six different germplasm of Chuanxiong Rhizoma in Sichuan province were collected for multipoint comparison field experiment.Different germplasm corresponding biological yield of Chuanxiong Rhizoma medicinal materials

component content (extract

volatile oil and ferulic acid) and cadmium content combined with three different kinds of corresponding medicinal materials quality were determined

correlation between quality and cadmium content of Chuanxiong Rhizoma with its germplasm. Result: Quality of Chuanxiong Rhizoma with different germplasm had some differences

Chuanxiong Rhizoma with germplasm of Z-6 (Wawushan town

Hoanya county

Meishan city) had a relatively good quality

followed by herbs with germplasm of Z-1 (Aoping town) and Z-2 (Chongzhou city)

quality of herbs with germplasm of Z-5 (Xiaoyudong town of Pengzhou city) was relatively poor.The content of cadmium in six different germplasm itself was the range of 0.31-2.10 mg·kg-1

and cadmium content in its corresponding herb was 0.23-0.59 mg·kg-1

there was no significant correlation of cadmium content between herb and germplasm (r=0.585

P=0.223). Conclusion: There are some differences among quality of Chuanxiong Rhizoma with different germplasm

there is little effect of germplasm on the content of cadmium in Chuanxiong Rhizoma

but effect of geographical factors on cadmium content in Chuanxiong Rhizoma is obvious.
