Elaeocarpus sylvestris var. ellipticus (Thunb.) H. Hara (Elaeocarpaceae) is the evergreen tree with shiny and oblanceolate leaves, native to Jeju island. It is known to have antioxidant, antiviral, and antibacterial activities, there are several trials undergoing to develop it as a useful resource. In this study, the skin-related activities and chemical profiles of plant parts of E. sylvestris var. ellipticus as cosmetic ingredients with low toxicity and good efficacy were investigated using sub-critical water extraction method and fermentation method by Latilactobacillus curvatus (fruit fermentation, period 1-3-5 days, respectively). As a result, HPLC profiles showed that each extract showed similar patterns, but the sub-critical water leaf extract of E. sylvestris var. ellipticus (ELS-SWE) has the highest gallic acid content. Anti-oxidant, anti-acne as well as whitening activities were also highest in ELS-SWE, because it contained the highest amount of gallic acid among the other samples tested. From these results, the ELS-SWE can be suggested as a cosmetic whitening material with low-toxicity.
