应用指纹图谱区分降香黄檀中油梨和糠梨魏建华,李冠斯,黄学泓,许如苏(汕头海关技术中心,广东汕头515031)摘要应用高效液相色谱法研究降香黄檀中油梨和糠梨的指纹图谱,采用相似度分析软件进行分析比较,分别获得17个油梨的共有特征峰和6个糠梨的共有特征峰;根据相对峰面积,初步建立降香黄檀中油梨和糠梨鉴定方法。结果表明,该方法结果准确、重复性好,所建立的指纹图谱可作为降香黄檀中油梨和糠梨的辅助鉴定,鉴定指标客观,鉴定方法简便,实现一定意义上的无损伤检测。关键词高效液相色谱;指纹图谱;降香黄檀;油梨;糠梨中图分类号S781.1文献标识码A文章编号0517-6611(2023)03-0202-03doi:10.3969/j.issn.0517-6611.2023.03.046开放科学(资源服务)标识码(OSID):ApplicationofFingerprinttoDistinguishOilPearandBranPearinDalbergiaodoriferaWEIJian-hua,LIGuan-si,HUANGXue-hongetal(ShantouCustomsTechnologyCenter,Shantou,Guangdong515031)AbstractThefingerprintsofoilpearandbranpearinDalbergiaodoriferawerestudiedbyhighperformanceliquidchromatography(HPLC).Thesimilarityanalysissoftwarewasusedtoanalyzeandcomparethefingerprints,and17commoncharacteristicpeaksofoilpearand6com-moncharacteristicpeaksofbranpearwereobtainedrespectively.Accordingtotherelativepeakarea,apreliminaryidentificationmethodofoilpearandbranpearinDalbergiaodoriferawasestablished.Theresultsshowedthattheprecisionandrepeatabilityofthemethodweregood.TheestablishedfingerprintmapcouldbeusedastheauxiliaryidentificationofoilpearandbranpearinDalbergiaodorifera,whichwasakindofobjectiveidentificationindex,simpleidentificationmethodandcouldrealizedamage-freedetectioninsomesense.KeywordsHighperformanceliquidchromatography;Fingerprint;Dalbergiaodorifera;Oilpear;Branpear基金项目海关总署科研项目(2021HK204)。作者简介魏建华(1977—),女,山西大同人,高级工程师,硕士,从事检验检测技术方面的研究。收稿日期2021-06-21红木作为一类珍贵的木材资源,它不是树木分类学上某个树种的名称,而是来源于明清时代的宫廷、王府及不同地区的生产者和经销商,经长期自然形成的经过归类的木材商品名。由于其具有特征性颜色与良好物理力学性能而备受人们青睐,在不同时代不同地区红木都有着不同的内涵[1]。由于红木类资源非常短缺,随着国民经济的快...
