摘要:

以废弃杉木板为原料制备木醋液,采用萃取法研究了不同萃取剂对木醋液中活性组分的富集作用。实验结果表明:乙酸乙酯、氯仿和乙醚3种萃取剂对酚类物质具有良好的富集效果,其中乙醚效果最显著;乙酸乙酯和氯仿对酮类物质具有良好的富集效应;3种萃取剂对酯类、醛类和醇类富集作用不明显,而不利于酸类物质的富集。添加甲醇有助于增强乙醚对酚类物质的富集作用,当乙醚与甲醇体积比为2:1混合萃取时,对酚类物质富集作用最显著,GC含量可达66%,是原木醋液的1.96倍。

Abstract:

The enrichment effect of different extraction agents on active components of wood vinegar from waste fir plate was studied. The results showed that different extraction agents exhibited different effects on the enrichment of active components in wood vinegar. Ethyl acetate, chloroform and ether exhibited good enrichment effect on phenolic substances, which ether present better extraction performance; ethyl acetate and chloroform had good enrichment effect on ketones; 3 extractants had no obviously enrichment effect on esters, aldehydes and alcohols, and they were not conducive to the enrichment of acid substances. Methanol addition was contributed to increase the enrichment effect of ether on phenolic substances. When the volume ratio of ether to methanol was 2:1, GC content of phenolic compounds reached to 66%, which was 1.96 times that of un-treated wood vinegar.

Key words: wood vinegar, active components, extraction method, enrichment, GC-MS analysis
