Abstract: The red pigment was extracted from Millettia reticulata Benth and the physical and chemical properties of red pigment from Millettia reticulata Benth were investigated, the effects of light, temperature, pH value, oxide-reducing medium on pigment stability were studied. The results showed that the procedure of acid-alcohol extraction gave rather satisfactory results. The pigment does not belong to anthocyanins, and is stable below 20-60 ℃, but its resistance to oxide and reductant is not good.

Key words: Millettia reticulata Benth, red pigment, physical and chemical properties, stability
