The effects of temperature on the visual color deterioration of Lithospermi radix were investigated under steady conditions of various pH and temperature. The changes of Hunter L, a, b, and delta E values related to the color deterioration were sharply increased above 50 deg C and the deteriorations were expressed linear relationships with the temperature above 60 deg C. Linear regression coefficients of hunter L, a, b, values decreased with the increase of heat treatment time, whereas the color difference was increased
