Abstract: The UV-vis Spectrum and the CIELab value of Black Rice Anthocyanins Extract were investigated and sevearal factors such as pH value, ethanol, NaCl and Sucrose on the UV-vis Spectrum and the CIELab value of Black Rice Anthocyanins Extract were determined.The total anthocyanins of two kinds of Black Rice were 84.2mg/100g,284.2mg/100g,and 23.9% in Black Rice Anthocyanins Extract.The UV-vis Spectrum of Black Rice Anthocyanins Extract indicated that the main anthocyanin was petunidin-3(6’ malonylglucoside).In the four factors mentioned above,the pH value was the manor factor influncing the UV-vis Spectrum and the CIELab value of the Black Rice Anthocyanins Extract.

Key words: Black Rice Anthocyanin pigment UV-vis Spectrum CIELab value
