The paper carries on qualitative analysis to the acetone extractives before and after discoloring, shows the main components of the extractives and then takes comparison. The results shows :①The hydroxyl is oxidized and then shifted to the carbonyl,carboxyl, ester and ketone groups during inducing discoloration under the pretreatment conditions,which makes the wood color deep;② There are plenty of auxochromic groups in the acetone extractives of silver chain, the interaction between the auxochromic groups and the chromophoric groups makes the wood color deep.

摘 要：本文通过对刺槐变色前后丙酮抽出物的定性分析，得出变色前后丙酮抽出物的主要成分，进行对比分析，初步得出抽出物对诱发变色的作用为：①变色前后羟基在预处理条件下氧化成羰基，羧基，酯基和酮基等官能团，使木材颜色加深；②刺槐丙酮抽出物的主要成分中含有大量助色基，这些基团会与木素中的发色基团相互作用，使木材颜色加深。

The hydroxyl and carboxyl, belonging to auxochromic groups, were oxidized into the carbonyl and ester groups, belonging to chromophoric groups, during inducing discoloration under the pretreatment conditions, which makes the wood color deeper. There 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 made the wood color deeper.

结论］羟基、羧基等助色基团在预处理条件下氧化成羰基、酯基等发色基团，使木材的颜色加深；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。
