采用气相色谱-质谱法分析柚木光辐射前后的抽提物成分,考察了柚木光辐射前后的颜色和组成变化,确定了可能引起柚木光变色的主要成分。结果显示,柚木光照100 h后黄蓝指数变化最为明显,表面变成金黄色,从柚木光辐射前后的抽提物中共鉴定出76种成分,其中柚木光辐射前的抽提物中鉴定出55种成分,柚木光辐射后的抽提物中鉴定出49种成分,包括烃类、醇类、酚类、酯类、醛类、酮类、蒽醌类和胺类,辐射后的柚木抽提物中烯烃类从20.11%减少至8.80%,由5种烯烃类减少为4种;酮类从0.99%增加到9.19%,由5种酮类增加为9种;杂环类化合物从20.56%减少到1.54%,由6种杂环类减少为1种。柚木单板表面光辐射后变亮、变黄...

Chromatography-mass spectrometry was used to analyze extractive compounds in Teakwood before and after irradiationandthe variations of the color and compositions in Teakwood before and after irradiation was studied. The results showed that the changes of yellow blue index was most significant and Teakwood surface can turn into golden yellow. Besides, there were 76 kinds of compounds were identified in all and 55 compounds in Teakwood before irradiation, while there were 49 compounds in Teakwood after irradiation, including hydrocarbons, alcohols, phenols, esters, aldehydes, ketone, anthraquino...
