Study on the Supplement Methd for Quality Identification of Residual SO_2 in Lily Bulb

YANG De-quan,YUAN Hong The Drug Inspection Insistute of Xiangxi Autonomy Area,Jishou,Hunan,China,416000  
Objective: To establish the supplement method for quality indentification of residual SO2 in Lily Bulb processed with traditional sulphur smoking.Methods: According to the character that SO2 dissolved water easilym,making residual SO2 in Lily Bulb water-soak to become sufurous acid.Sufurous acid could make iodine solution reduction and color fading,also reacted with baruium chloride to become white precipitation.Results: All residual SO2 sample showed positive reaction,Lily Buld without sulphur smoking showed negative reaction.Conclusion: Through two reaction result can identify if residual SO2 exist in trial sample,with strong specificity,can be as the supplement method for quality identification of residual SO2 in Lily Bulb.
