Abstract	겔투과 크로마토그래피와 실리카겔크로마토그래피등을 이용하여 여러가지 천연아스팔트에서 금속포르핀을 얻었으며 크로마토그래피 용액을 알루미나로 처리한 후 피리딘으로 추출하여 보다 농축된 금속 포르피린을 얻을 수 있었다. 금속 포르피린에서 포르피린 고리를 파괴하지 않고 금속을 제거하여 여러가지 형태의 프르피린을 얻었다. Porphyrin-rich materials were obtained from some crude asphalts by gel permeation chromatography and silica gel chromatography. After extraction of each chromatographic fractions through alumina with pyridine, more concentrated metalloporphyrins were obtained. Demetallation of metalloporphyrins was possible without destroying porphyrin ring to provide different type of metal free porphyrins.
