摘要：以6种不同品种的松木材为原料,通过溶剂抽提得到不同品种松木的石油醚和甲醇提取物,并采用GC-MS和LC-MS分析其化学成分,同时采用牛津杯法评价不同品种松木提取物对密粘褶菌的抑菌效果。结果表明:6种松木石油醚提取物中共鉴定出45种化合物,主要为萜类、酯类和脂肪酸等物质;6种松木甲醇提取物中共鉴定出59种化合物,主要为酚类、有机酸类和黄酮类等物质;松木石油醚和甲醇提取物对密粘褶菌的生长均具有一定的抑制作用,且松木石油醚提取物的抑菌效果要优于甲醇提取物,表明松木中萜类、酚类等次生代谢产物对松木材防腐性能具有重要影响。
Six different kinds of pine woods were used as raw material.The ether and methanol extracts from different kinds of pine woods were obtained by solvent extraction,and the chemical composition of petroleum ether and methanol extracts were analyzed by GC-MS and LC-MS technology.Oxford cup method was used to evaluate antibacterial effects of Gloeophyllum trabeum for different petroleum ether and methanol extracts of pine wood.The results showed that 45 compounds were identified from pine petroleum ether extracts,mainly terpenoids,esters and fatty acids of 6 pine species.A total of 59 main compounds were identified from the methanol extracts of 6 pine species,mainly including phenols,organic acids and flavonoids.The petroleum ether and methanol extracts had certain inhibitory effect on the growth of Gloeophyllum trabeum.The inhibitory effect of petroleum ether extracts of pine were better than that of methanol extracts,which indicated that terpenoids,phenols and other secondary metabolites in pine had important influence on the anticorrosive performance of pine wood.
