摘要
本文报道了分别采用甲醇、乙醇、水作为溶剂提取红菜苔色素的工艺及光谱特性，其最大吸收峰为５３０ｎｍ；并对ｐＨ值、光、热等因素对其稳定性的影响作了深入研究。
The spectral character and extraction of red pigment from Brassica Campestris L individually with methanol, alcohol and water were reported. The maximum absorptivity is at 530nm. Effect of the PH value, heat and sun- light on the stability were researched in depth.
