해조류중 미역, 다시마, 곤피, 청각, 파래 및 김을 물, 메타놀, 핵산 및 에칠에테르로 추출한 엑스분의 항돌연변이 효과를 Salmonella typhimurium/microsome 계로 실험하였다. 물로 추출한 엑스분은 TrP-P-2와 aflatoxin $B_1$에 다소 효과가 있었고, 메타놀의 엑스분중 다시마, 곰피는 Trp-P-2에 효과가 있었으며, 메타놀 엑스분을 plate 당 1.0mg, 2.0mg 함유하는 모든 시료는 MeIQ와 aflatoxin $B_1$에 효과가 있었다. 에칠 에테르의 엑스분은 곰피와 청각이 매우 효과가 있었고, 특히 6종류의 해조류중 에칠 에테르의 엑스븐은 MeIQ와 aflatoxin $B_1$에 대하여 우수한 효과가 있었다.
Extracts of six seaweeds obtained from solvents such as water, methanol, hexane and ethyl ether have been tested for desmutagenic activities in the Salmonella typhimurium/microsome systems. Water extracts obtained from tangle, sea-tangle, and gompi were moderately effective on the mutagenicity of Trp-P-2 and aflatoxin $B_1$. Methanol extracts of sea-tangle and gompi were effective against Trp-p-2, and all samples of methanol extracts were very effective from 1.0mg to 2.0mg per plate on the mutagenicity of MeIQ and aflatoxin $B_1$. Hexane extracts of tangle, ses-tangle, gompi and sea-straghorn were very effective on the mutagenicity of Trp-p-2, MeIQ and aflatoxin $B_1$ except laver and green laver. Ethyl ether extracts of gompi and sea-straghorn were most effective from 1.0mg to 2.0mg per plate on the mutagenicity of Trp-P-2. Especially, ethyl ether extracts of all samples were great effective on the mutagenicity of MeIQ and aflatoxin $B_1$.
