To overcome side effects of dandruff medications, many researches on natural anti-dandruff compounds are actively being conducted. Here, we tried to isolate and identify antifungal compounds against four Malassezia species (M. restricta, M. globosa, M. furfur, M. sympodialis) from Cinnamomoum cassia Blume. Cinnamomum cassia Blume was extracted with 80% (v/v) ethanol for 7 days. The extracts were purified by solvent fractionation, silica gel column chromatography and HPLC. The purified compound was identified for the active peak with 1H-NMR and <SUP>13</SUP>C-NMR. Among 5 solvent fractions, only hexane fraction (CHF) showed antifungal activity. The data showed that CHF has higher activity than that of Zinc pyrithione (ZPT) in M. furfur, and lower than that of ZPT in M. restricta, M. globosa and M. sympodialis. Thus, CHF has been further purified by silica gel column chromatography and Prep-HPLC. The analysis of 1H-NMR and <SUP>13</SUP>C-NMR revealed that structure of isolated compound is coumarin. Coumarin showed the antifungal activity of 11.5 mm, 10.1 mm, 14.2 mm and 19.8 mm for M. furfur, M. restricta, M. globosa and M. sympodialis, respectively. MIC50 values of coumarin were 79.09 μg/mL, 133.91 μg/mL, 63.41 μg/mL and 19.72 μg/mL for M. furfur, M. restricta, M. globosa and M. sympodialis, respectively. The anti-inflammatory activity of coumarin at concentrations of 0.013∼0.855 nM showed that coumarin inhibited nitric oxide production by 18∼22% in RAW 264.7 cell. These data suggest that Cinnamomum cassia Blume extracts and its isolated coumarin are good candidates for dandruff medications.
