方法 硼替佐米中的异戊醛用 2,4-二硝基苯肼衍生化，采用 Waters symmetry C 18 色谱柱（250 mm × 4.6 mm ，5 µm ），以乙腈（体积分数 0.1% 甲酸）-水（体积分数 0.1% 甲酸）为流动相进行线性梯度洗脱，流速为 1.0 mL•min -1，检测波长为 364 nm ，柱温为 30 ℃。
结果 异戊醛质量浓度在 0.015～2.998 mg•L -1 内与峰面积呈良好线性关系（r = 1.000 0），平均回收率为 101.1%，RSD 为 1.4%。
结论 该方法准确灵敏、线性范围宽，可以用于稳定性过程中潜在基因毒性杂质异戊醛的评估。

方法本研究利用拟南芥AtCOP1蛋白序列,用HMMER3程序和在线程序SMART,在丹参全基因组数据库筛选到丹参中的E3泛素连接酶SmCOP1序列,经RT-PCR技术获得丹参cDNA,以其为模板设计引物扩增,并利用生物信息学方法对该基因及其编码蛋白进行相关分析。
通过酵母双杂实验对其调控丹参酮和酚酸物质机制进行初步研究。
结果结果表明SmCOP1的2个蛋白均为不稳定亲水性蛋白,其N-端为环形锌指结构域(RING–finger),C-端为WD40重复结构域。
通过建立进化树表明SmCOP1b和AtCOP1是直系同源的关系,而SmCOP1a和SmCOP1b是旁系同源的关系。
Y2H实验显示SmCOP1a与SmPAP1互作。
结论成功克隆并预测分析丹参E3泛素连接酶SmCOP1,并初步发现其可能通过靶向MYB转录因子SmPAP1对其泛素化修饰参与调控酚酸类物质的代谢。

超高效液相色谱-串联质谱法测定化妆品中15种N-亚硝胺化合物
第42 卷第 11 期2023 年11 月Vol.42 No.111469~1478分析测试学报FENXI CESHI XUEBAO（Journal of Instrumental Analysis）超高效液相色谱-串联质谱法测定化妆品中15种N-亚硝胺化合物汪毅1，梁文耀1，何国山1，陈张好2，周智明2，吴谦1，席绍峰1，谭建华1*（1．广州质量监督检测研究院，国家化妆品质量检验检测中心（广州），广东广州511447；2．广东省药品检验所，广东广州510663）摘要：采用超高效液相色谱-串联质谱（UPLC-MS/MS）建立了化妆品中15种痕量N-亚硝胺化合物的分析方法。
水剂样品以水或乙腈分组超声提取，膏霜乳液样品采用亚铁氰化钾-乙酸锌溶液沉淀大分子或者饱和氯化钠-乙腈盐析分组处理后，以Agilent Poroshell 120 SB-Aq（100 mm×3.0 mm，2.7 μm）色谱柱分离，经大气压化学电离源（APCI）电离，多反应监测模式检测，以同位素内标法定量。
结果表明，15种N-亚硝胺化合物在相应质量浓度范围内线性关系良好（r2＞0.995），检出限和定量下限分别为5~15 ng/g和15~45 ng/g。
水、乳、膏霜3种化妆品基质在25、50、100 ng/g加标水平下的平均回收率为88.0%~111%，相对标准偏差（RSD，n=6）为1.4%~9.8%。
该方法用于市售化妆品检测，发现13批次样品检出N-亚硝基二乙醇胺（NDELA），其中1批次超限量值。
方法的专属性强，灵敏度高，精密度好，解决了N-亚硝胺化合物稳定性差、易被干扰等问题，适用于化妆品中15种N-亚硝胺化合物的痕量测定。

The final estab⁃lished method involved ultrasonic extraction of cosmetics using water or acetonitrile for different com⁃pounds. The samples were treated with potassium ferrocyanide-zinc acetate solution for precipitating macromolecules or saturated sodium chloride-acetonitrile for salting out.An Agilent Poroshell 120 SB-Aq（100 mm × 3.0 mm，2.7 μm） chromatography column was used for separation，followed by atmospheric pressure chemical ionization（APCI） source and multiple reaction monitoring mode detec⁃tion in the isotope internal standard method for quantification. The result showed good linearity（r2> 0.995） for the 15 N-nitrosamine compounds in their respective concentration ranges，with detection and quantitation limits of 5-15 ng/g and 15-45 ng/g，respectively.The average recoveries for the three cosmetic matrices（aqueous，emulsion，cream） at spiked levels of 25，50，100 ng/g were be⁃tween 88.0% and 111%，with relative standard deviations（RSD，n=6） of 1.4%-9.8%. The method was applied to the detection of commercial cosmetics and N-nitrosodiethanolamine（NDELA） was de⁃tected in 13 batches，with one batch exceeding the limit.
