l-Muscone is synthesized for use as substitutive material of musk which is the active ingredient of woohwangchungsimwon. The objective of this investigation was to evaluate the acute and subacute toxicity of l-muscone in rats. In oral acute toxicity test, SPF Sprague-Dawley male and female rats were gavaged with l-muscone of two doses(0, 5.0g/㎏). No dead animal and abnormal autopsy findings were found in control and treated group. Body weights were slightly decreased in both sexes of rats treated with 5.0g/㎏. Therefore, oral LD_50 of l-muscone was consider to be higher than 5.0g/㎏ in male and female rats. In intraperitoneal acute toxicity test, rats were injected intraperitoneally with dosages of 0, 1,000, 1,316, 1,732, 2,279 and 3,000 ㎎/㎏. Decreased body weights and motor activities were observed at high dose group. Intraperitoneal LD_50 of l-muscone were 1,920 ㎎/㎏ in male and female rats. In the subacute study. l-muscone was administrated orally to both sexes of rats for 4 weeks as several doses(0, 10, 100 and 1,000 ㎎/㎏). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data suggest that no observed adverse effect level of l-muscone in rats might be over 1,000 ㎎/㎏/day in this study.
