Exposure to house dust mites is closely connected with allergic diseases such as atopic dermatitis, allergic rhinitis, and asthma. House dust mites (Dermatophagoides farinae and D. pteronyssinus) act as allergens even after their death. Therefore, repelling the house dust mites is more effective method than killing them. Many chemical agents have been used in killing house dust mite. However, it is usually reported that these chemical agents (acaricides) exhibit adverse effects and toxicity toward animals and human. For these reasons, we carried out the experiments for measuring the repellent activity of Mate tea and Jasmine tea against house dust mites in this experiment. In order to determine the concentration having the most effective repellent effect of Mate and Jasmine tea, house dust mites (D. farinae and D. pteronyssinus) were exposed at different concentrations (0, 0.015625, 0.03125, 0.0625, 0.125, 0.25, 0.5 mg/40 μL) of Mate tea and Jasmine tea extracts, respectively, for different hours (0.5, 1, 2, 3 hours). The most effective repellent effect (%) against house dust mite in 0.25 mg/40 μL of Mate tea for 2 hours was 73.5%, Jasmine Petal tea in 0.0625 mg/40 μL for 1 hour was 84.1% and Pearl Jasmine tea in 0.125 mg/40 μL for 0.5 hour was 82.8%. These results suggest that Mate tea and Jasmine tea extracts have potential effect to repel the house dust mites (D. farinae and D. pteronyssinus)

본 연구는 최근 기능성 차 소재로 알려져 있는 mate의 특유의 맛과 향을 개선하기 위하여 발효공정을 적용하였으며 발효공정 단계별 유용성분 분석을 통해 품질특성을 비교하였다. 발효 전 mate 추출물에서는 탄닌 함량이 로 측정되었으나 발효 후 덖기 과정 및 최종 건조과정을 거침에 따라 각각 , 로 유의성 있게 감소하였다. 총 폴리페놀 및 총 플라보노이드 함량은 발효 전 mate 추출물에서 각각 43.45 mg/g, 0.86 mg/g이었으며 발효
