樟树叶提取物对木材腐败菌的抑菌性研究

Inhibitory Activity of Cinnamomum camphora Leaves Extracts on Selected Wood Fungi and Moulds

分别采用水和苯-乙醇提取樟树[Cinnamomum camphora(L.)Presl]叶,用杯碟法测定2种提取物对木材腐朽菌、霉菌及变色菌的抑菌性。结果表明:樟树叶苯-乙醇提取物抑菌测试效果不明显,但樟树水提取物对木材腐朽菌和霉菌具有抑制作用。当测试浓度为5%时,对木材白腐菌黄孢原毛平革菌、褐腐菌密粘褶菌、哈慈木霉菌、产紫青霉菌、烟曲霉菌均有明显抑制,高浓度(10%)时能抑制蓝变菌可可球二孢菌。

The experiments of water, benzene/ethanol extracts from Cinnamomum carnphora leaves to two kinds of wood fungi（Phanerochaete chrysosporium, Gloeophyllum trabeum ）, three kinds of wood moulds （Penicillium purpurogenum,Trichoderma harzianum, Aspergillus funigatus ）and one kind of wood stain fungus（Botrydiplodia theobromae ） have been carried through respectively by using a cylinder plate method. The results showed that benzene/ethanol extract from （Tinnamomum camphora leaves have no zones of inhibition to all of the tested fungi. In contrast, The water extract from Cinnamomum camphora leaves indicated positive antifungal activity ,with the concentration of 5 % exhibiting the best antifungal performance to all tested fungi except Botrydiplodia theobromae. The inhibition to Botrydiplodia theobromae appeared when the concentration of water extractfrom Cinnamomum camphora leaves came to 10%.
