    Silver Chain is firstly taken as research object for the analyses of induced discoloration; the paper carried on content determination of extractives of Silver Chain, analyzed the color different and the vision physics parameters before and after discoloring under different pretreatment conditions, and, took the samples for chromatographic analysis by infrared spectrum and GC-MS. The results showed: (1)The color of Silver Chain tended to be dark and uniform gray-brown; (2)Under the condition in high temperature steaming, the color of Silver Chain was much more uniform; (3)The preliminary conclusion of the effect of extractives in induced discoloration was:①After induced discoloration,The carbonyl (-C=O) and the conjugated double bond(C=C)increase, belong to chromophoric groups, which made the wood color deeper;②There were plenty of auxochromic groups and chromophoric groups in the acetone extractives of silver chain, the interaction between the auxochromic groups and the chromophoric groups makes the wood color deeper.

    研究结果表明:(1)刺槐颜色的变化趋势向深色方向变化,可获得均匀的深褐色;(2)高温汽蒸条件下,处理后木材颜色更加均匀;(3)初步得出抽出物对诱发变色的作用为:①经诱发变色处理后的刺槐丙酮抽出物中,含有羰基-C=O等发色基团的物质浓度有所升高,与芳环共轭的C=C也有所增加,促使了刺槐颜色加深;②刺槐木材丙酮抽出物的主要成分中含有大量发色基团和助色基团,这些基团间的相互作用使木材颜色加深。
