Sulfur dioxides and sulfites are registered in "The Japan's Specifications and Standards for Food Additives" mainly used as bleach and anti-oxidants, and Food Sanitation Law prohibits the use to sesame, legumes and vegetables. In China, sulfur fumigation is performed for the purpose of bleaching, drying, insecticide and antibacterial to some crude drugs. Recently, it has been reported that large quantities of sulfur dioxides are detected from sulfur fumigated crude drugs. In the course of our study of the survey of impurity in herbal materials, we analyzed the content of sulfur dioxides for 31 kinds of crude drugs (5 companies, 151 herbal materials) purchased from the Japanese market. By using modified Rankine method, more than 1,000 ppm of sulfur dioxides was detected from three crude drugs (Dioscorea Rhizome, Gastrodia Tuber, Fritillaria Bulb) and also more than 500 ppm of sulfur dioxides was detected from seven crude drugs (Pueraria Root, Lilium Bulb, Ginger, Asparagus Tuber, Platycodon Root, Mulberry Bark, Forsythia Fruit). Since herbal materials such as Dioscorea Rhizome, Pueraria Root, Lilium Bulb, Ginger are used as food and food additives, sulfur dioxide content of these materials should be noted at the viewpoint of food safety.
