摘　　要：本文采用纸上层析荧光扫描法测定松馏油及其提取物A、B中苯并(a)芘[B(a)P]的含量。样品经索氏提取器提取后,再以咖啡因-甲酸提取液提取,经乙酰化滤纸纸层析分离,用荧光薄层扫描法测定各样品中B(a)P的含量。结果表明,松馏油及其提取物A、B中B(a)P的含量分别为6171.3、2285.2、129.6ppb,其中以松馏油提取物B中B(a)P的含量最低。In this paper, the B(a)P contents of pine tar and its extractives A,B were determined by PC-Scanning method. After combining extraction by caffeine and formic acid with PC-Scanning method, the B(a)P contents were obtained. The results showed the B(a)P contents of pine tar and its extractives A,B were 6171.3 pp,2285.2 ppb,129.6 ppb, among them, the B(a) P content of B was the lowest.
