Abstract

Oriental mineral medicines are single or mixture of more than one mineral species or rock/fossil which are used to treat disease. Mineral medicines remove harmful or useless substances to decrease toxicity and secondary effects, and cause the manufacture of medical compounds with increased efficacy. The extraction test is an accepted in vitro system to predict the bioaccessibility of major and minor elements from mineral medicine. It incorporates gastrointerstinal tract parameters representative of a human body that including stomach and small intestinal pH which are the same as digestion condition. The bioaccessibility of a mineral medicine is the fraction that is soluble in the gastrointestinal environment and is available for absorption. Reaction path modeling in the human body can predict digestion with gastric fluid as well as absorption in the small intestine, existence in body fluids and reaction progress of the exhaust process according to pH conditions in body. Also reaction path modeling can predict bioavailability, which is equal to existence rate in the body and the form and amount of a medicine in the body after intake. The study results from predicating the existence form mineral medicines in the body, and proving the effective ingredient using bioaccessibitily and human risk assessment, suggest these that should be necessary data for new medicine development.

광물성 약재(광물약)는 오랜 기간 동안 주로 중국, 한국 등 동양의 전통의학에서 화학성분이나 물리적인 성질이 질병치료나 건강 증진에 이용되어 왔던 단일 광물, 암석 및 생물화석 등을 의미한다. 광물성 약재는 산지의 지질특성, 기후 및 지표 환경에 의해 광물학적 특성이 달라지며, 광물의 조직, 수반광물, 정제 방법에 따라 약재로서의 효용성이 달라진다. 특히, 광물성 약재에 함유되어 있는 광물조성, 주성분 및 미량성분의 차이는 광물약의 약효와 유해성에 영향을 준다. 그러므로 광물약의 분석방법과 전처리 및 제조과정에 대한 표준화가 매우 중요하다. 광물성 약재에 함유된 유해 금속 원소는 수치(법제)나 탕약 제조 등 약제의 전처리 과정과 위와 장에서의 소화과정에서 성분이 변화되어 용출량이 결정되기 때문에 체내와 대응되는 조건에서의 적절한 시험방법을 정립하여, 그 결과에 의해 위액용출도, 인체흡수도, 안정성과 위해성이 평가되어야 한다. 또한, 광물성 약재의 안정성과 위해성을 평가할 수 있는 연구결과로 유효성분과 독성 물질의 체내 존재량을 예측할 수 있어야 한다. 연구에서 제안된 광물성 약재의 표준화 방법은 광물약의 개발과 활용에 유용한 기초자료로 이용될 뿐만 아니라, 광물성 약재의 품질 표준을 규격화 하는 기준을 제시해줄 것으로 기대된다.
