Abstract

A previous study of ours indicated that Citrus auranifoli oil possesses antifungal activity against Malassezia furfur and Malassezia pachydermatis. In this study, we evaluated the anti-M. furfur and M. pachydermatis activities of limonene, which is a major component of C. aurantifolia oil, using the disk diffusion method. We also examined cytotoxicity against human normal epithelial (Beas-2B) cells using the cytopathic effect reduction (CPE) method. The results revealed that the minimum fungicidal concentration (MFC) value of limonene is lower than the value for itraconazole. The MFC value of limonene was seen to be 7.81 ${\mu}g$/mL against M. furfur and 3.90 ${\mu}g$/mL against M. pachydermatis. MFC values of itraconazole against M. furfur and M. pachydermatis were 62.50 ${\mu}g$/mL and 31.25 ${\mu}g$/mL, respectively. In addition, it was noted that limonene was not toxic to Beas-2B cells with normal morphology at a concentration of 100 ${\mu}g$/mL. However, itraconazole exhibited weak toxicity at the same concentration. Therefore, our results indicate that limonene could potentially be effective at controlling M. furfur and M. pachydermatis infections with no cytotoxicity.

우리의 이전의 연구에서 Citrus auranifoli 오일은 Malassezia furfur와 Malassezia pachydermatis에 대해 항곰팡이 활성을 나타낸다는 것을 보여주었다. 본 연구에서 Citrus auranifoli 오일의 주요 성분인 리모넨(limonene)의 M. furfur와 M. pachydermatis에 대한 저해효과를 디크스 확산 방법(disk diffusion method)에 의해 측정하였고, Beas-2B 세포에 대한 세포독성을 cytopathic effect reduction 방법에 의해 측정하였다. Limonene의 최소곰팡이저해농도(minimum fungicidal concentration)는 양성대조구인 itraconazole보다 더 낮았고, 100 ${\mu}g$/mL의 농도에서 Beas-2B cells에 대한 세포독성을 나타내지 않았다. 그러나 itraconazole은 같은 농도에서 약한 세포독성을 나타내었다. 그러므로, 우리의 결과에서 limonene는 비세포독성과 함께 M. furfur and M. pachydermatis의 성장저해를 하는데 효과적이라는 것을 보여준다.
