摘  要：
【目的】分析不同种类中药煎煮液对菜心体内多环芳烃(PAHs)的净化效果,为降低PAHs污染蔬菜风险提供参考依据。【方法】利用萘(NAP)、菲(PHE)、荧蒽(FLT)、苯并(α)蒽(Ba A)和苯并(α)芘(Ba P)5种PAHs混合液涂抹菜心1 d后,再采用板蓝根、大青叶、淫羊藿、银杏叶、麦冬和黄芪6种中药煎煮液分别喷洒菜心植株,7 d后检测分析菜心体内5种PAHs含量的残留情况。【结果】使用6种中药煎煮液(浓度分别为50.0、100.0和200.0 g/L)喷洒PAHs涂抹胁迫的菜心后,检测到菜心体内的NAP、PHE、FLT、Ba A和Ba P含量分别为1.58~1.71、0、0~3.86、1.63~2.15和3.62~5.63μg/kg。6种中药煎煮液对PHE均有显著的净化效果(P<0.05),其中,板蓝根煎煮液对NAP和大青叶煎煮液对Ba P的净化效果较明显,淫羊藿煎煮液对FLT的净化效果较佳,100.0 g/L淫羊藿煎煮液对Ba A也有一定的净化作用。【结论】中药煎煮液对菜心体内PAHs的净化效果与中药种类有关,与其使用浓度关系不密切,其中以大青叶和淫羊藿煎煮液的净化效果较佳。

摘  要：
【Objective】The purification effects of different kinds of traditional Chinese medicine decoction liquid on the polycyclic aromatic hydrocarbon(PAHs)in Chinese flowering cabbage were analyzed. It provided reference for reducing the PAHs pollution risks of vegetables.【Method】The mixed liquids of five kinds of PAHs were used to daub Chinese flowering Cabbage for 1 d,and then six kinds of traditional Chinese medicine decoction liquid were used to spray on it.After 7 d,the residual of PAHs contents in the vegetable were detected and analyzed. The five kinds of PAHs were naphthalene(NAP),phenanthrene(PHE),fluoranthene(FLT),benzo(a)anthracene(Ba A),and benzo(a)pyrene(Ba P),while six kinds of traditional Chinese medicine were radix isatidis,folium isatidis,herba epimedii,ginkgo leaf,radix ophiopogonis and Astragalus membranaceus.【Result】After spraying the Chinese flowering Cabbage with the three concentrations(50.0,100.0 and 200.0 g/L)of six kinds of traditional Chinese medicine decoctions liquid which was daubed by PAHs,the contents of NAP,PHE,FLT,Ba A and Ba Pe in Chinese flowering cabbage were 1.58-1.71,0,0-3.86,1.63-2.15 and 3.62-5.63 μg/kg respectively. The purification effects of six kinds of traditional Chinese medicine decoction liquid on PHE were significant(P<0.05),and the purification effects of radix isatidis on NAP and those of folium isatidis on Ba P were obvious. The purification effects of herba epimedii on FLT were sound,and herba epimedii also had certain purification effects on Ba A.【Conclusion】The purification effects of traditional Chinese medicine decoction liquid on PAHs in Chinese flowering Cabbage are related to the kinds of traditional Chinese medicine,but are not closely related to concentration. The purification effects of folium isatidis and herba epimedii decoction liquid are fine.
