Abstract

This study was carried out to investigate the residual sulfur dioxide residues ($SO_2$) in commercial medicinal herbs in Korea in 2013. Among a total of 116 samples of 11 different kinds of herbs, 71 samples (11 Kinds) were domestic, and 45 samples (10 Kinds) were imported. The residual contents of $SO_2$ in the samples were determinated by a modified Monier-Williams method. Of the 116 samples, 6 samples (5.2%, 4 Kinds) failed to meet the regulations for sulfur dioxide residues of KFDA in medicinal herbs. Among 6 unsuitable samples, 1 samples (1.4%) were domestic, and 5 samples (11.1%, 3 Kinds) were imported. The highest amount of sulfur dioxide residues was 1546.3 mg/kg (Lycii Fructus) in the domestic samples. Regardless of region, $SO_2$ contents were not found at Anemarrhenae Rhizoma, Citri Unshius Pericarpium, Eucommiae Cortex, Forsythiae Fructus, Gardeniae Fructus, Leonuri Herba and Lonicerae Folium et caulis. These data will be used as a basic data for the future legislation on the regulation and control of sulfur dioxide of herbal medicines.

국내에 유통되고 있는 국산과 수입산 한약재 11종 116건을 대상으로 잔류이산화황에 대한 모니터링을 수행한 결과 108건(93.1%)은 불검출이었고 6건(5.2%)는 이산화황 허용기준치 30 mg/kg을 초과하였고 2건은 30 mg/kg 미만으로 검출되었다. 116건의 이산화황 평균함량은 $17.6{\pm}144.2mg/kg$이고 최대 검출량은 구기자(1,546.3 mg/kg)이었고 중국산 현호색(66.6%)의 이산화황 검출 빈도가 가장 높게 나타났다. 국내산 한약재는 71건 중 1건(1.4%), 수입산 한약재는 45건 중 7건(15.6%)에서 이산화황이 검출되었고 국내산 1건(36.7 mg/kg)과 수입산 5건(118.1 mg/kg)이 허용기준치를 초과하여 국내산보다 수입산 한약재에 이산화황 잔류량이 많았다. 본 연구를 통해 이산화황 허용기준을 초과하는 부적합율은 다소 낮아지고 있지만 이산화황 허용기준을 초과하는 한약재들 중 일부 한약재에서는 잔류이산화황 함량이 높게 나타났고, 특히 국내산 약재에 비해 수입산 약재는 부적합율이 높게 나왔다. 한약재는 일반적으로 수세 및 가열과정을 거치므로 실제 섭취하는 형태의 탕액에서는 원재료보다 이산화황의 잔류량이 크게 감소하지만 완전히 제거되지는 않으므로 유통되는 한약재의 안전성 확립이 절실히 요구되어진다. 강화된 기준이 정착하여 안전한 한약재가 유통될 수 있도록 수입통관시 특별관리가 요구되며, 보다 적극적인 검사 요주의 품목에 대한 지속적인 잔류이산화황 모니터링이 필요할 것으로 사료된다.
