The photometric determination of chlorophyll. in the fresh tea leaves and made tea was researched.<BR>A high correlation coefficient between the chlorophyll concentration and the optical density of the acetone extract of tea by a red filter was existed, and a regression line of chlorophyll concentration upon the optical density of the extract was obtained.<BR>By this regression line, the variation of the chlorophyll concentration of the samples during. the tea manufacturing process and the storage: was measured.
