| Abstract: | Brown pigment is extracted from Chestnut shell as raw material. The paper studies the effects on different solvent concentration, solid-liquid ratio, extraction time, extraction temperature and stability of the coarse brown pigment. The results showed that brown element： the best condition ;under the condition 75 ℃, 2 h were extracted with 1% NaOH, and solid-liquid ratio of 1：10, under the condition the extraction rate can reach 16.8%.Brown pigment stability test showed that the pigment in alkaline conditions has good stability, good stability, within the range of 100 ℃ of oxidant and reducing agent has good tolerance. |
