The increase in the consumption of herb medicines have made their use a public health problem due to the potential fungal contamination and the risk of the presence of mycotoxins. 360 samples of herb medicines were evaluated for the aflatoxin contamination. The natural occurrence of aflatoxins in these samples were determined using immunoaffinity column clean up and high performance liquid chromatography (HPLC) with post-column derivatization. For samples analyzed, mean levels (incidence) of AFB1, AFB2, AFG1 and AFG2 in positive samples were 1.4 μg/kg (46.4%), 0.4 μg/kg (25.4%), 1.1 μg/kg (37.8%) and 0.9 μg/kg (24.3%), respectively. Recoveries of the full analytical procedure were 71.7~99.7% for AFB1, 88.1~99.2% for AFB2, 82.8~95.5% for AFG1 and 77.9~90.0%for AFG2. The excess cancer risk estimated using the cancer potency of aflatoxin B1 (7 (mg/kg/day)−1 for HBsAg− and 230 (mg/kg/day)−1 for HBsAg+) were 1.30 × 10^(−5) ~ 1.22 × 10^(−7) for hepatits B surface antigen negative (HBsAg−) and 3.31 × 10^(−4)~ 3.12 × 10^(−6) for hepatits B surface antigen positive (HBsAg+) respectively. In conclusion, although the contamination levels of samples used in the study were low, further actions are also required to undertake a program of herbal surveys in order to access mycotoxin contamination overall so that the safety of public will be protected.
A survey of total aflatoxin levels was conducted on 145 samples(carthamiflos, thujae semen, giycyrrhizae radix et rhizoma) collected in Yakyeang markets in Seoul. Aflatoxin levels were quantified by the immunoaffinity column clean-up method followed by performance liguid chromatography(HPLC)-fluorescence detector(FLD). Aflatoxins were found in 10(6.9%)samples including 5 Arecae semen, 4 Thujae semen, 1 Zizyphi semen with a range of 0.45~79.15 μg/kg. Generally These results show that the contamination level of aflatoxins in Herb Medicines consumed in Korea is high compared with the standard in Korea Herb Medicine Code(10 μg/kg as aflatoxin B1). It is considered that aflatoxin concentration was increased in herb medicines during a storage and drying in herb medicines examined
화장품은 일반인이 장기간 연용하는 제품으로 인체 피부에 대한 안전성이 매우 중요하다. 화장품에 의한접촉피부염은 자극성 물질이 피부에 접촉 후 침투하여 유발하는 염증반응으로 활성화된 면역세포에서 염증을 매개하는 다양한 인자를 분비함으로써 시작된다. 본 연구에서는 국산 생약 추출물을 이용하여 RAW264.7 대식세포에서 염증 관련 인자에 대한 영향을 통해 항염증 활성을 스크리닝 하였다. 51종의 국산 생약 추출물 중 측백, 측백엽(초), 향부자, 형개, 동과자, 산약, 산약(초), 상지, 송절, 택사의 에탄올 추출물 10종이 lipopolysaccharide(LPS)에 의해 유도된 세포독성을 감소시킴과 동시에 염증 관련 인자인 Nitric oxide (NO),interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α의 생성을 억제하는 것을 확인하였다. 또한, 이들 생약 추출물은 인체피부에서도 자극을 유발하지 않음을 인체 첩포시험을 통해 검증하였다. 따라서, 항염증활성이 확인된 10종 국산 생약 추출물은 피부 자극을 예방할 수 있는 화장품 소재로서의 활용이 가능할 것으로 사료된다.
Our paper shows the results of 302 samples of herb medicines about fungal contamination at Yakyeang markets in Seoul. The sample medicines were treated VICAM pretreatment and analysed by post column derivatisation procedure(PHRED-HPLC) with a fluorescence detector. Aflatoxin B1 was founded from 50.3% of samples, aflatoxin B2 was 39.7%, aflatoxin G1 was 21.2% and aflatoxin G2 was 23.5%. The detected ranges of aflatoxin B1, B2, G1 and G2 were from 0.1 to 57.2 μg/kg, 0.1 to 42.6 μg/kg, 0.1 to 23.5 μg/kg and 0.1 to 9.5 μg/kg respectively. Among total samples, 26 samples contained aflatoxin B1 violated the regulation (less than 10 ug/kg) for aflatoxin B1 of KFDA. From the result, we could presumed that more than a half of samples were contaminated by aflatoxins. Therefore, it seems to be necessary that the new safety giudeline will be established aflatoxin B2, G1 and G2 from herb medicines as aflatoxin B1.
한약재 추출물로 재배한 콩나물의 무게와 길이변화 및 조단백질 함량을 조사한 결과, 한약재중에서 콩나물 무게와 길이의 증가는 대조구에 비하여 인삼 추출물이 가장 효과적이었고, 다음으로 감초가 효과적이었다. 당귀와 천궁 추출물 은 대조구와 비슷하였고, 황련 추출물은 오히려 억제되었다. 인삼과 감초의 추출물 농도는 각각 200 ppm 및 100 ppm에서 콩나물 무게와 길이의 증가에 효과적이었다. 인삼 추출물에서 콩나물의 무게는 대조구에 비하여 재배일
