ABSTRACT
OBJECTIVE:
To know the residual characteristics of organochlorine pesticides and 5 kinds of heavy metals (Cu, As,Cd,Hg and Pb) in Panax notoginseng.METHODS:
P. notoginseng samples with 3 years were collected from Baiyi Town, Songming County and Liushao Township,Xundian County of Yunnan Province in Apr. 2013. 60 strains of P. notoginseng and 1 kg rhizosphere soil samples were also collected. The organochlorine pesticide residues and 5 kinds of heavy metals on its various parts and soil samples were detected. Pesticide residues determination method in Chinese Pharmacopoeia(2010 edition,volumeⅠ)was conducted to determine the organochlorine pesticides and 5 kinds of heavy metals (Cu,As,Cd,Hg and Pb).RESULTS:
There was pentachloronitrobenzene in different parts of P. notoginseng from Baiyi Town,Songming County,and the contents were root bark>fibrous≥notches>ribs>leaves;there were pentachloronitrobenzene only in the root bark and fibrous of P. notoginseng from Liushao Township,Xundian County,and the contents were root bark>fibrous. No Hg was detected in any part of P. notoginseng samples,and the other heavy metals were highest in root bark;As and Pb were relatively high in soil,the contents of As and Pb in samples were far lower than in soil.CONCLUSIONS:
The contents of pesticide residues and heavy metals in different parts of P. notoginseng are different,and those in root bark are relatively high. P. notoginseng sample contains organochlorine pesticides, which is mainly pentachloronitrobenzene;P. notoginseng sample has relatively strong accumulation of Cd.
