天然金珍珠和染色金珍珠的致色因素和鉴定分析方法研究进展郭倩;徐志【摘要】金属离子、卟啉和类胡萝卜素是天然金珍珠的主要致色成分，有机染料是染色金珍珠的致色成分。
鉴定天然金珍珠和染色金珍珠的主要手段有常规观察检测、紫外可见吸收光谱法、拉曼光谱法、荧光光谱等。
本文结合天然金珍珠的致色成分和染色金珍珠的染色方法，对两类金珍珠的鉴定技术作了评述，认为常规观察检测是十分必要的，染色珍珠颜色分布不均匀，在孔眼内或表面破损处可看到染料的沉淀浓集；紫外可见吸收光谱法是目前较为常用的鉴定方法，天然金珍珠主要吸收峰位于350~360 nm，而染色金珍珠则出现明显的410~450 nm谱峰；应用拉曼光谱法鉴定可获得天然金珍珠在275 cm-1明显的特征峰，而染色金珍珠出现强的荧光背景峰；应用荧光光谱法鉴定金黄色天然珍珠在376 nm处光激发时谱峰是以472 nm为中心，而染色珍珠在372 nm处受光激发时谱峰位于436 nm。
这些鉴定方法仍然在实验验证阶段，进一步优化和开发新的测试手段则是今后重要的发展方向。
%Color-causing components of natural golden pearls are mainly metal ions,porphyrin and carotenoids. Organic dyes are the color-causing components of dyed pearls. Conventional observation,UV-vis Absorption Spectroscopy,Raman Spectroscopy,and Fluorescence Spectroscopy are used to distinguish natural from dyed pearls. The identification methods of the two types of pearls( natural golden and artificially dyed golden ) are reviewed and presented in this study. Conventional observation is necessary because the color of dyed pearls is not homogenous and dye can be concentrated in the hole or any damaged surface. UV-vis Absorption Spectroscopy is a commonly usedidentification method. The main absorption peaks of natural golden pearls lie between 350 nm and 360 nm,whereas those of dyed pearls lie between 410 nm and 450 nm. Raman Spectroscopy has identified that natural golden pearl has a characteristic peak of 275 cm-1 ,but dyed pearl has a strong fluorescence background peak. Fluorescence Spectroscopy has identified that the natural golden pearl has a central peak of 472 nm as excitation by 376 nm light,whereas the dyed pearl has a central peak of 436 nm as excitation by 372 nm light. Further verification of these identification methods should be undertaken,along with improvements in optimization and the development of new methods.【期刊名称】《岩矿测试》【年(卷),期】2015(000)005【总页数】8页(P512-519)【关键词】金珍珠;致色成分;常规检测;紫外可见吸收光谱法;拉曼光谱法;荧光光谱法【作者】郭倩;徐志【作者单位】广东省地质实验测试中心，广东广州510080;广东省地质实验测试中心，广东广州510080【正文语种】中文【中图分类】O657.32;O657.37;O657.34金黄色海水珍珠，属于南洋珠的一种，产自白唇贝或金唇贝中(大珠母贝)，两种贝的主要产地在澳大利亚北部、印尼群岛、菲律宾、缅甸、日本以及泰国关沙梅和中国三亚。

The beam is focussed onto the sample that sits on an XYZ-movable stage (3) through a microscope objective, and can be viewed live on screen thanks to an integrated CMOS camera (4). The scattered light produced is then collected by the same objective before being passed through a filter to remove unwanted laser light. The Raman scattered light passes through an adjustable confocal pinhole (5) before entering the spectrograph. One of five possible diffraction gratings splits the light into its constituent wavelengths (6) which are then focussed onto the detector(s) (7) and displayed to the user as a spectrum.1Multiple LasersUp to 3 integrated and computer-controlled lasers with choice of wavelengths, combined with a computer-controlled continuous laser beam attenuator to allow control over laser power at the sample position.3High Performance MicroscopeThe latest generation research-grade upright microscope (Olympus BX53series), allows the RM5 to benefit from all modern sample visualisation and contrast enhancement techniques availableincluding brightfield, darkfield, polarised light, Nomarski differential interference contrast (DIC) and fluorescence.

二、期刊简介如下是西安交通大学主办、教育部主管的学术理论刊物，2011年1月由“Academic Journal of Xi’an Jiaotong University：《西安交通大学学报（英文版）》”，经报请教育部、科技部、新闻出版总署批准，于2011年2月更名为“Journal of Pharmaceutical Analysis（JPA，药物分析学报)”。
JPA为国内外公开发行的英文学术期刊，季刊。
JAP主要集中反映与药品质量、用药安全和分析方法等相关的最新研究成果，重点报道：（1）中药（药材、成药、方剂、注射剂）分析；（2）药物复杂体系分析；（3）生物技术药物质量控制技术与方法；（4）药物体内作用过程分析；（5）药物发现过程中的定量与定性分析；（6）分子药理学中的示踪分析；（7）生物药剂学中的定量分析；（8）临床检验与生物分析等。
栏目有：Review、Original Articles 和 Short Communication。
JPA是世界上第一份有关药物分析的专业学术期刊，主编由西安交通大学医学院药物研究所所长、中国药学会药物分析专业委员会主任委员贺浪冲教授担任。
JPA目前被美国《化学文摘》（CA）和荷兰《医学文摘》（EM）收录，并进入中文科技期刊数据库、万方数据库、中国学术光盘数据库(CNKI) 和重庆维普数据库等多家国内著名检索系统。
