目的 通过对正品檀香及其市售混伪品进行比较研究,找出特征性鉴别点。方法 采用性状鉴别、显微鉴别、薄层鉴别、挥发油含量测定及气相色谱-质谱联用自动解卷积定性系统(GC-MS-AMDIS)自动智能化成分鉴定等手段,对正品檀香及其市售混伪品进行比较研究。结果 性状鉴别中,檀香独有的奶香味为其鉴别点;显微鉴别中油脂的颜色,分布及方晶数量可用于区分正伪品;伪品的挥发油成分与正品檀香差异较大,且不以檀香醇为主要成分;挥发油的含量测定可作为最准确、简便的检验手段,用以判断檀香样品是否符合药典标准的规定。结论 建立正品檀香及市售混伪品的鉴别方法,并给檀香的质量评价提供依据。

OBJECTIVE To find out the characteristic identification points by comparing the genuine sandalwood and its counterfeit products on the market. METHODS Macroscopical identification, microscopic identification, thin-layer identification, determination of volatile oil content, and GC-MS-AMDIS intelligent composition identification were used to study the differences between the genuine sandalwood and its commercial counterfeit products. RESULTS The unique milk fragrance of sandalwood was used as the identification point in the macroscopical identification. The color and distribution of the oil, and the number of the calcium oxalate crystals in the microscopic identification can be used to distinguish. The volatile oil composition of the counterfeit products are quite different from the genuine sandalwood, and it does not use santalol as the main ingredient. The content of volatile oil can be used as the most accurate and simplest method to determine whether a sandalwood sample meets the requirements of the pharmacopoeia standard. CONCLUSIONT Establish the identification method of genuine sandalwood and its counterfeit products, and to provide the basis for the quality evaluation of sandalwood.
