Objectives : Other than the traditional uses as the natural coloring matters, the gardenia seeds and the gallnuts have been used as the materials for the foods and the Oriental medicines. And, recently, as the naturally-derived substances, they have been utilized in the diverse fields. Although, regarding most of the natural dyes which are tinged with the colors, because they abundantly possess the polyphenol and the useful, secondary metabolites, they have the antioxidation and anti-bacterial efficacy, because the colorings of the skin and the stabilities of the materials are low, there are the difficulties with regard to the use. In this research, by using the gall nuts and the gardenia seeds, the research had been conducted for the verification of the efficacy as the cosmetic product materials, for the durability of the naturally-dyed, non-woven fabric, and for the production of an anti-bacterial, non-woven fabric.
Methods : In order to secure the visual beauty and the functional aspect, the gall nut and the gardenia seeds had been used as the complex extracts.
Results : Their anti-oxidant activities were analyzed to be 22.5/9.3 ㎍/㎖, respectively, regarding the DPPH/ABTS. And the inhibition (IC50, 11.3 ㎍/㎖) of the tyrosinase activity was, also, analyzed to be on a high level. This was excellent to the extent that it was comparable to the ascorbid acid, which had been used for the positive control. Not only that, regarding the anti-inflammatory efficacy and the anti-bacterial effect, too, the result on a far higher level compared to the other extracts was obtained.
Conclusion : In the light of such results, it is judged that there are a lot of the utilizations of the natural dye materials for making the raw, cosmetic product materials. And it is thought that, by carrying out the in-depth clinical researches at the same time, it will be able to be applied as a material with the safe and excellent efficacy.
