中文摘要：
为了掌握市场上林源中药饮片中二氧化硫的残留情况,从而为林业资源的利用、林药资源加工技术规范的制定与执行以及林产品的安全监测提供参考依据,采用在国家标准的基础上自行改进的检测方法,对从市场上收集到的31种林源中药饮片中二氧化硫的残留量进行了检测。结果表明：未检出二氧化硫的有3种;二氧化硫含量〈30 mg/kg的有20种;其含量为30~150 mg/kg的有3种;其含量为151~400 mg/kg的有3种;其含量〉400 mg/kg的有2种。根据《中华人民共和国药典》中对中药饮片残留量的限制规定和文中的检测结果,黄柏、牡丹皮、合欢皮、陈皮、八角茴香等中药饮片的二氧化硫残留量超标,建议在林产品利用和监管时要特别加以注意。
