본 연구는 후추추출물, 클로브버드, 로즈마리 및 오리가늄오일의 친환경 살충소재의 활용기능성을 탐색하고자 급성경구독성, 급성경피독성, 피부자극성 및 안점막자극성시험을 수행하였다. 랫드를 이용한 급성경구독성시험결과 후추추출물, 클로브버도 로즈마리 및 오리가늄오일의 LD??은 2,000 ㎎/㎏ bw이상이었고, 급성경피독성시험결과 모든 시험물질의 LD??이 4,000 ㎎/㎏ bw으로 나타났다. 피부자극성시험결과 후추추출물, 클로브버드 및 로즈마리오일은 자극성이 없었고, 오리가늄오일은 중도의 자극성을 나타냈다. 안점막자극성시험결과 후추추출물과 로즈마리오일은 자극성이 없고, 클로브버드오일은 경도의 자극성을 나타냈으며, 오리가늄오일은 중도의 자극성을 나타냈다. 따라서, 후추와 로즈마리오일은 독성이 낮았으나, 클로브버드오일은 경도의 안점막자극성을 갖고, 오리가늄오일은 중도의 피부자극성과 안점막자극성이 있는 것으로 구분되었다.
Highly bio-active plant essential extracts and oils from pepper, clove bud, rosemary and origanum which are selected to develop environment-friendly insecticides was studied for their acute toxicity. The results of acute oral toxicity using rats showed LD?? value of over 2,000 ㎎/㎏ bw for pepper, clove bud, rosemary and origanum oils. The calculated acute dermal LD?? value of pepper was over 4,000 ㎎/㎏ bw and anther testing materials was over 4,000 ㎎/㎏ bw. The skin irritation test showed that pepper, clove bud and rosemary oils had no irritation while origanum oil had a moderate irritation. According to the eye irritation test, it showed that there was no irritation for pepper and rosemary oils, while there were irritation for clove bud and origanum oils. Consequently, pepper and rosemary oils were shown to be low in toxicity whereas clove bud oil was indicated to cause a mild eye irritability and origanum oil, causing a moderate skin and eye irritability.
