Naturally air-aged commercial samples of USP or reagent-grade cholesterol contain components which are mutagenic towards Salmonella typhimurium strains TA1537, TA1538 and TA98. These mutagenic components are associated with the polar cholesterol autoxidation products, but identify of the mutagenic components has not been achieved. Pure crystalline nonmutagenic cholesterol free from autoxidation products becomes mutagenic towards these strains upon heating at 70° in air or following exposure to 60Co γ-radiation.
