Abstract

The optimum extraction conditions of green tea used for a bath were investigated for later application to textile. The extraction was more effective in water and methanol than in ethanol. The optimum extraction temperature was determined as 80$^{\circ}C$ in water and 60$^{\circ}C$ in methanol. The extracts were more stable in acid and neutral conditions than in alkaline region. The UV satbility was better than generally expected. From the analysis of contents of active ingredients, the about 20% of effective catechin was appeared to be contained in the extract solid. The contents of polyphenol is 0.016g in the 0.1g extracts.
