摘　　要：对6种唇形科中草药及其水提液的铅、铬含量进行了分析,根据中药材中重金属含量标准进行污染指数评价。结果显示:6种唇形科生药中铬含量均超过标准;水提液中除了白花夏枯草外,其余的铬含量都符合标准。而6种唇形科生药中铅含量超标的有白花夏枯草、香薷、宝盖草和线纹香茶菜;水提液中除线纹香茶菜外,其余5种铅含量都符合标准。因此,中草药的使用安全性值得重视。The contents of Pb and Cr in 6 kinds of labiatae crude herbs and their decoctions were deter- mined. According to the evaluation standards of heavy metals in medicinal herbs, pollution indexs on Pb and Cr were analyzed. Results showed that the contents of Cr were over standard in the crude herb. While Cr in decoc- tions were in accordance with the standard except Lagopsis supine. The contents of Pb were over standard in the crude herbs including Lagopsis supine, Elsholtzia eiliata , La mium a m plexicaule and Rabdosia lophanthoi- da. While Pb in decoctions were in accordance with the standardexcept Rabdosia lophanthoida. Therefore the security of the herbs would be worth attention.
