Degradation kinetics of chlorophyll pigments in dried leaves of Polyscias fruticosa (L.) harms during storage

Chlorophyll is well-known as the only natural green pigment that owns high biological values with an enormous amount worldwide. In this study, the experiment was designed to a two-level factorial design with three factors, including storage temperature (4 and 28oC), level of light (with or without light transmission through the package), and level of oxygen (high and low oxygen concentration in package).
