摘要：檀香心材是国际公认的天然高级香料的主要来源,亦是中国传统中药的重要原料。檀香心材的形成较为缓慢,资源奇缺,而其边材尚未加以利用。为了更好地开发利用檀香资源,实现高效利用,以21年生檀香木材为研究对象,采用乙醚浸提法分别提取了其边材和心材的精油,并应用气相色谱—质谱联用仪(GC-MS)对其组分及含量进行了对比分析。结果表明:檀香心材的精油含量显著高于边材(P<0.001),其平均相对含量分别为4.44%和1.33%;檀香心材的α-檀香醇、β-檀香醇和总檀香醇的平均相对含量分别为46.95%、24.23%和75.97%,均显著高于边材,精油质量达到了檀香木油的贸易标准,而边材精油则未达到该标准;檀香边材精油亦含有檀香油的主要成分,且含有一些烷烃、醛和不饱和酸等成分,可加以利用。本研究结果不仅有助于增进了解檀香心材形成过程中的成分变化,而且可以为檀香边材资源的综合开发利用提供理论依据。
Heartwood of sandalwood is the main source of natural perfumes and important materials for traditional Chinese medicine.It generally takes a long time to form fragrant heartwood in sandalwood,and the international market is in short supply,while its sapwood has not been used yet. In order to utilize sandalwood resources comprehensively,variations of essential oil content and composition between heartwood and sapwood from Indian sandalwood（ Santalum album） were studied through diethyl ether extraction and gas chromatography-mass spectrometry（ GC-MS） using wood samples from 21-year-old sandal plantations in Jianfengling,Hainan Island,China. The results showed that essential oil content in heartwood was significantly higher than that in sapwood（ P〈0. 001）,the mean oil contents in heartwood and sapwood were 4. 44% and 1. 33%,respectively. Contents ofα-santalol,β-santalol and total santalol in heartwood were 46. 95%,24. 23% and 75. 97% in average,which significantly higher than those in sapwood. Oil quality in heartwood accorded with the international standard for trade,while in sapwood,oil quality did not reached the standard. Nevertheless,alkanes,aldehydes,unsaturated acids as well as major ingredients of sandalwood essential oil were detected in sapwood,which could also be utilized. These findings can not only be helpful to improve understanding composition changes during heartwood formation of sandalwood,but also provide evidences for further utilization of sapwood resources of this species.
