| Panax notoginseng (Burk.) F. H. Chen, also known as sanqi or notoginseng, is a Chinese medicine plant of the Araliaceae family. There are many requirements for environmental conditions. The medicinal material is mainly produced in wenshan of Yunnan province. Pharmacological studies indicate that Panax notoginseng has hemostatic, anti-thrombotic, anti-atherosclerotic and anti-aging effects. It is applied in many regions. It has proved that Panax notoginseng planting area was polluted by arsenic, which influenced it’s normal growth and medicinal quality. The previous research proves that stabilizer could promote Panax notoginseng growth. This paper through adding 30 mg/kg,70 mg/kg,150 mg/kg arsenic to soil do pot experiment. Research Panax notoginseng growth and medicinal quality was effected by arsenic. Through indoor stabilization experiment select suitable stabilization materials. Using selected materials did pot experiment. Research Panax notoginseng growth and medicinal quality was effected by stabilization remediation. The main results were as follows:(1)The low concentration of As in soil promoted the growth of Panax notoginseng, whereas high concentrations of As inhibited the growth. The results indicated that improve in the survival rate of Panax notoginseng and increase in the growth of root, stem and leaf when adding 30 mg/kg As in soil; in addition, the contents of active ingredients, the content of PNS and three kinds of main monomer saponins (Rg1,Rb1 and R1) have increased. Moreover, the survival rate has increased by 18% and the biomass in root has increased by 10% after transplanting 270 days. However, the growth conditions became relatively poor using 70mg/kg and 150 mg/kg As in soil, respectively; and decreased in survival rate, biomass, and content of active ingredients.(2) The content of TCLP decreased to different extent using FC, Fe, Zeolite, and Fe2O3, in which FC, Fe, and Zeolite contacted to better effect on stabilization efficiency than Fe2O3, which decreased by 81.13%,77.35%, 31.55%, respectively. Zeolite has increased pH in soil for 1.35, but no significant effect on pH using FC, Fe and Fe2O3.(3) As mainly exists in F3 and F4 in control soil, which was 66.21% in total As, and F1 was less only in 0.33%. However, the content of F2 was relatively high, in 30.39%, which had potential risk in As activation. Decreased significantly in F1+F2 using FC, Fe, Zeolite, and Fe2O3, and increased in F3+F4, in which the effect on F1+F2 shown as follow:FC> Fe> Zeolite and Fe2O3, and the values were 4.38%,3.63% respectively in FC and Fe.(4)Panax notoginseng biomass, the survival rate, the content of total saponins, monomer saponins, total flavonoids have increased after adding FC, Fe to As polluted soil; but the content of total arsenic has decreased. In addition, the medicinal quality in Panax notoginseng has increased, which indicated that the stabilization remediation has a significant effect.(5) The distribution characteristics of As in Panax notoginseng grown in high As soil were leaf>root>stem.
