Abstract: Dynamic changes of soluble sugars, protein, amino acids, vitamins C (VC) and vitamins E (VE) of color pepper were studied.The results showed the content was the highest such as soluble sugars in 2734, protein in nest raw chili peppers and VC in 96-47-2-1, they were 68.07, 42.0, 1.70mg·g-1 FW, respectively.2734 had the lowest amino acids content of 121.72 μmo·lg-1 FW, 2734 and 96-47-2-1 had higher VE (0.65and 0.62mg·g-1 FW, respectively) . The results also showed the periods of peaks of different nutrients were different, the contents of protein and soluble sugars were the highest at the mature stage, amino acids and VC were the highest at the early development, VE was the highest at the middle development. Taking together, selection of different varieties and harvest period were according to the purpose of nutrients.
