摘要:
 采用生长速率法测定了甲醇、乙酸乙酯、丙酮、三氯甲烷和蒸馏水5种不同溶剂黄枝润楠木材提取物对木腐菌生长的抑制作用，以探明黄枝润楠木材的抑菌能力。结果表明，提取物的得率与溶剂的极性呈正相关；除蒸馏水外，其余4种溶剂对木腐菌均有不同程度的抑制作用；随着提取物浓度的增加，抑制作用增强；三氯甲烷对白腐菌的抑制率最大73.22%，甲醇对褐腐菌的抑制率最大96.93%，两提取物的EC50值均最低，分别为1.480 1 g·mL-1和0.475 2 g·mL-1；在抑制采绒革盖菌和密黏褶菌方面，提取的最适溶剂分别为三氯甲烷和甲醇。研究结果为黄枝润楠木材的合理利用提供科学依据。
Abstract:
 In order to reveal the antifungal activities，extracts from Machilus versicolora wood were prepared by five different solvents: methanol,ethyl acetate,acetone,chloroform and hot water.The results showed that the yield of the extracts was positively correlated with the polarity of solvent.All extracts had antifungal activity against wood-decaying fungi except for hot water extracts.The higher the extract concentration was,the stronger inhibition activity was.Chloroform extract had the best antifungal effect on Coriolus versicolor while for Gloeophyllum trabeum,it was methanol extract,which were 73.22% and 96.93%.The EC50 values of the two extracts were the lowest as well,which were 1.480 1 g·mL-1 and 0.475 2 g·mL-1,respectively.The results would provide a scientific basis for the rational use of M.versicolora wood.
