Abstract

This study was investigated to determine the contents of sulfur dioxide residues in medicinal herbs in Seoul Yang Nyoung Shi in 2010 (1,522 samples of 189 kinds). Samples were measured by modified Monier-Williams method. of the total samples, 618 samples (84 kinds) were domestic, and 904 samples (158 kinds) were imported. The content of sulfur dioxide in the domestics showed the range of 0.0 to 1,298.0 mg/kg (average 12.7 mg/kg), while those in imported samples were the range of 0.0 to 3,982.2 mg/kg (average 42.4 mg/kg). The average (mg/kg) amount of sulfur dioxide by parts in medicinal herbs was as follows; Tuber 122.3, Radix 69.3, Rhizoma 37.4, Cortex 33.3, Fructus 8.8, Ramulus 4.9, Semen 4.6, Folium 3.4, Flos 2.7, Perithecium 1.4. of the total samples (1,522), 52 samples (3.4%) were violated the KFDA regulatory guidance of sulfur dioxide. Among these 52 unsuitable samples, 16 samples (7 kinds) were domestic, and 36 samples (23 kinds) were imported. Approximately 88.1% of the total samples was less than 10 mg/kg of sulfur dioxide and 6.3% of the total samples showed more than 30 mg/kg of sulfur dioxide.

본 연구는 시중 유통 한약재 총 189품목 1,522건(국내산 84품목 618건, 수입산 158품목 904건)을 대상으로 모니어-윌리엄스변법에 따라 잔류이산화황을 측정하였으며, 전체 한약재의 잔류이산화황 평균은 30.3 mg/kg, 국내산의 평균 잔류량은 12.7 mg/kg(검출범위 0.0-1,298.0 mg/kg), 수입산의 평균 잔류량은 42.4 mg/kg(검출범위 0.0-3,982.2 mg/kg)으로 수입산이 국내산보다 약 4배가량 높게 나타났다. 한약재 중 1,330건(88.1%)이 10 mg/kg 이하 함유량을 나타냈고, 그 중 219건(14.4%)은 전혀 검출되지 않았으며 192건(11.9%)만이 인위적 함유량으로 추정되는 10 mg/kg을 초과하였다. 사용부위별 잔류량을 살펴보면 Tuber, Radix, Rhizoma, Cortex에서 평균 잔류량이 각각 122.3, 69.3, 37.4, 33.3 mg/kg순으로 나타났고 Cortex, Radix, Tuber의 평균 잔류량이 국내산의 경우 각각 2.1, 24.2, 5.6 mg/kg인 것에 반해 수입산의 경우 53.5, 116.1, 191.3 mg/kg으로 나타나 상당한 차이를 보였다. 전체 한약재 중 52건(3.4%)이 허용기준을 초과하였는데, 수입산 한약재에서 기준을 초과한 한약재는 모두 중국산으로 766건 중 36건(4.7%), 국내산은 총 618건 중 16건(2.6%)이 허용기준을 초과하였다. 국내산의 경우 7품목 16건 모두 30 mg/kg이하의 기준이 적용되어 부적합으로 판정된 것으로 갈근(298.8 mg/kg), 길경(1030.1 mg/kg), 독활(163.8 mg/kg), 사삼(290.0 mg/kg), 작약(89.3 mg/kg), 목통(73.0 mg/kg), 산약(420.4 mg/kg)이 기준을 초과하였고, 특히 산약의 경우 의뢰된 국내산 산약 5건 모두 기준을 초과하였다. 수입산은 23품목 36건이 기준을 초과하였는데 이 중 반하1건과 시호1건은 기존의 200 mg/kg이하의 기준 적용으로 각각 269.3, 552.7 mg/kg으로 검출되었고, 천마 1건과 황금은 기존기준인 500 mg/kg이하의 기준 적용으로 각각 847.3, 3982.2 mg/kg의 결과를 보였으며, 그 외 다른 품목들은 모두 30 mg/kg이하의 기준 적용으로 나온 결과였다.
