摘要 为了解同一产地,不同结香方法及结香时间对沉香品质的影响,笔者利用气相色谱-质谱联用技术(GC-MS)分析了广东省化州市5批沉香样品挥发性成分及其相对含量。5批沉香样品中凿洞法结香11个月的沉香挥发油得率最高为4.93%,冷铁打洞法结香13个月的沉香样品挥发油得率最低为2.29%。5批沉香样品中共鉴定出72个色谱峰,其中共有峰12个。挥发油成分均主要由倍半萜类,2-(2-苯乙基)色酮类及脂肪酸类化合物组成。从打钉法结香8年的沉香样品中发现具有芳香气味的5,11-环氧愈创木烷倍半萜内酯类化合物——奇楠内酯,为首次从普通沉香中鉴定出的奇楠内酯。火烙法的结香速度优于打铁钉法及冷铁打洞法。沉香结香时间越长挥发油得率越高,挥发油成分的种类及相对含量越稳定,品质越好。 The volatile constituents and their relative contents of five batches of Chinese eaglewood sampled from Huazhou,Guangdong,China were analyzed by GC-MS to investigate the influence of different eaglewood inducing methods and time on the quality of Chinese eaglewood from the same region. The highest yield of volatile oil in the five batches of the samples was 4. 93% and the lowest was 2. 29%. ? From all the samples were identified72 peaks,of which 12 peaks were common. The results showed that all the volatile oils of the five samples were mainly composed of sesquiterpenes,2-( 2-phenylethyl) chromones,and fatty acids. ? A lactone with an aromatic smell of the eaglewood induced from Aquilaria crassna,5,11-epoxy guaiane sesquiterpene lactone,was detected for the first time from the common Chinese eaglewood induced for 8 years by using the iron nailing method. The fire burning method induced eaglewood faster than the iron nailing method and cold iron holing method. The eaglewood with longer inducing time produced a higher yield of volatile oil,and the compounds of the volatile oil and their contents were much more consistent,indicating better quality of the volatile oils.
