摘要：【目的】检测20种真菌对白木香Aquilaria sinensis树体挥发油成分的影响。【方法】通过输液法的通体结香技术,将不同菌液注入广东省惠东县境内白木香树体内,运用GC-MS技术分析变色木质部乙醇浸出物的化学成分。【结果】经龙眼焦腐病菌Lasiodiplodia theobromae、斑点青霉Penicillium meleagrinum、黑绿木霉Trichoderma atroviride、拟康木霉T.koningiopsis、青霉病病原菌Pen.italicum、腐皮镰孢Fusarium solani、葡萄座腔菌Botryosphaeria rhodina这7种真菌菌液处理的白木香目标树乙醇浸出物的质量分数超过10%,且倍半萜、芳香族类和2-（2-苯乙基）色酮类相对含量之和分别为：21.57%、21.85%、24.02%、22.83%、23.49%、25.15%和24.84%,而其他13种真菌处理树体乙醇浸出物质量分数均低于10%,主要检出物质为脂肪酸和烷烃类物质,倍半萜和芳香族类物质的相对含量之和仅为2.67%～7.88%,不含2-（2-苯乙基）色酮类物质。【结论】20种待测菌种中,只有7种真菌能有效促进白木香树体沉香物质的形成,而其他13种真菌效用不明显。
[ Objective ] To determine the effect of 20 different fungi on compositions of essential oils from agarwood of Aquilaria sinensis. [ Method ] The whole-tree agarwood-inducing technique was used, and culture fluids of 20 fungal species were injected into A. sinensis trees separately. The chemical compositions of extracts from the 20 treatments were investigated using GC-MS method. [ Result ] The ethanol extract contents were above 10% from A. sinensis trees infected by seven fungal species including Lasiodiplodia theobromae ,Penicillium meleagrinum , Trichoderma atroviride , T. koningiopsis , Pen. italicum , Fusarium solani and Botryosphaeria rhodina. The total relative contents of sesquiterpenes, aromatics compounds and 2-（2-phenylethyl） chromone derivatives were 21.57% , 21.85%, 24. 02%, 22. 83%, 23.49%, 25.15% and 24. 84% respectively. For the rest 13 treatments, the ethanol extract contents were below 10%, the main detected ingredients were fatty acids and alkanes,the total relative contents of sesquiterpenes and aromatics compounds were only 2.67% to 7.88% , and no 2-（2-phenylethyl） chromone derivative was detected. [ Conclusion ] Among the 20 fungal species, seven species can efficiently induce agarwood formation in A. sinensis, and the effects of the rest 13 species are not obvious.
