摘要： 以长白落叶松心材、边材及树皮为原料,分别用乙醚、氯仿、丙酮、甲醇和水5种溶剂对其进行提取,采用滤纸片法研究了不同溶剂提取物分别对白腐菌和褐腐菌的抑菌性能,发现心材的甲醇提取物和丙酮提取物对白腐菌有较好的抑制效果,树皮的水提取物对2种菌都有较好的抑制效果.并研究了这两种提取物在室内对木材的防腐性能,借助扫描电子显微镜(SEM)照片观察了木材腐朽后菌丝生长的情况,与常用木材防腐剂酸性铬酸铜(ACC)进行了对比,结果显示:心材的甲醇提取物对白腐菌的抑制效果较好;而树皮的水提取物对褐腐菌抑制效果较好.

Abstract: Heartwood, sapwood and bark of olga hay larch (Larix olgensis var. changpaiensis) were used as raw material to obtain extractives by extracting with C2H5OC2H5,CHCl3, (CH3)2CO, MeOH and H2O,respectively. Antibacterial activities of these extractives against Coriolus versicolor and Gloeophyllum trabeumr were investigated by filter paper method. It was found that MeOH extractives and (CH3)2CO extractives of heartwood have better inhibition effect against C. versicolor; H2O extractives of bark has better inhibition effect both against C. versicolor and G. trabeum. Wood preservation activities of these two kinds of extractives were also studied in lab, the growths of wood-inhabiting fungi in samples were observed by scanning electron microscope (SEM). The effect was compared with typical wood preservative acid-copper-chromate (ACC), the result showed that MeOH extractives of heartwood has better decay-resistance against C. versicolor, H2O extractives of bark has decay resistance against G. trabeum.

Key words: olga hay larch(Larix olgensis var. changpaiensis), extraction, wood preservation
