Siping Institute for Food andDrug Control , Siping 136000, Jilin China )Abstract :A method for simultaneous determination of aflatoxins B 1, B 2, G 1, and G 2 in pheretima was been established by ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS), and the positive results was confirmed. The samples were extracted by 70% methanol, purified by a immunoaffinity columns, separated by UPLC-MS/MS, detected by triple quadrupole mass spectrometry, and confirmed by ion peak ratio. The results showed that the linear relationship of the four aflatoxins were good (r >0.999 5), and the recoveries ranged from 91.2% to 95.6%. The limits of detection for aflatoxin B 1, B 2, G 1, and G 2 were 0.10, 0.038, 0.11, 0.038 µg/kg, respectively. The method has a good specificity, high sensitivity, good accuracy, and can be used to determine the final positive detection. Aflatoxin were positively detected in 6 out of 15 batches of pheretima , which proved that the Pheretima were more susceptible to contamination by aflatoxins.Key words :Pheretima ;UPLC-MS/MS

黄曲霉毒素主要是由黄曲霉、寄生曲霉产生的次生代谢产物,是一组化学结构类似的化合物[1-2],主要包括AFB1、AFB2、AFG1、AFG2,多存在于土壤、动植物、各种坚果中[3],在湿热环境下出现黄曲霉毒素污染的概率最高. 黄曲霉毒素的危害性在于对人及动物肝脏组织的慢性毒性作用,长期积累可导致肝癌甚至死亡[4-5]. 各国药典均对黄曲霉毒素在中药材或中草药中的限量作了规定,如《欧洲药典》规定AFB1、AFB2、AFG1、AFG2总量在中草药中的限量不得高于4 µg/kg,《美国药典》规定AFB1、AFB2、AFG1、AFG2总量在中草药中的限量不得高于20µg/kg,《中华人民共和国药典》规定其总量在中药材中的限量不得高于10 µg/kg[6].地龙药材标准收载在《中华人民共和国药典》2020版一部[7]. 采收时需要及时剖开腹部,除去内脏和泥沙. 由于地龙生长在土壤环境中,故其被AF污染的风险较大. 目前AF测定的方法主要有液相色谱-柱后碘衍生化法或光化学衍生化法-荧光检测器以及酶联免疫法,但以上方法均存在假阳性的误判可能性,当超出标准限值时均需要采用质谱检测器进行阳性确证[8]. 本研究采用超高效液相色谱-串联质谱法(UPLC-MS/MS)同时测定不同产地多批次地龙药材中AFB1、AFB2、AFG1、AFG2的含量,并对阳性结果进行确证,从而准确的判定检出情况,为地龙药材中AF污染情况提供参考.1 试验部分1.1 仪器和试剂BT125D型电子天平(北京赛多利斯仪器天平有限公司),TDL-5-A型离心机(上海安亭科学仪器厂),AB SCIEX QTRAP®

免疫亲和柱技术和质谱测定法的优势免疫亲和柱技术是利用抗原、抗体之间高度特异性结合对目标物进行净化富集的一种实验技术,预置在柱体内的特异性抗体选择性结合样本中的待测物,杂质不被结合流出柱外,柱上结合的目标物再被洗脱液洗脱,从而实现目标物的高效净化和浓缩[9].质谱法是使待测化合物产生气态离子,再按质荷比(m/z)将离子分离、检测的分析方法,检测限可达10−15~10−12 mol数量级. 相比较液相色谱法,测试样品需要的量较少,其检测灵敏度也大幅度提高,且其较好的专属性可以作为液相色谱检出情况的进一步确证,大大降低误判阳性检出的情况[10-13]. 2.2 线性范围和检出限分别精密吸取1.3项下系列混合对照品溶液5µL,注入液相色谱仪,测定峰面积,以进样质量浓度(ng/mL)为横坐标,峰面积为纵坐标,绘制标准曲线.结果如表4所列,4种黄曲霉毒素的线性关系良好(r>0.999

AFB 2分别为85.0%、85.1%、85.1%、85.2%、85.3%、85.0%,相对平均偏差均小于0.2%. 均在允许偏差±20%内,确证样品阳性检出.3 结论由多批次样品检验情况可以初步得出,地龙药材中黄曲霉毒素的污染主要为黄曲霉毒素B 1和B 2.地龙药材在产地初加工过程中需去除泥沙,而泥沙为黄曲霉毒素污染的重要来源,如果泥沙去除不净、保存不当、遇湿热环境,则黄曲霉毒素含量容易超标[14-17]. 因此地龙药材的黄曲霉毒素监测检验非常必要[18-21]. 试验结果表明,UPLC-MS/MS 法操作简便、专属性好、灵敏度高、重复性好,能够对地龙药材的阳性结果作出准确判定,故将在中药材的黄曲霉毒素污染检测中发挥重要作用.参考文献:刘丽娜, 李海亮, 李耀磊, 等. 中药真菌毒素质量控制概况、限量标准制定及有关问题的思考[J ]. 中草药,2023,54(19):6197-6207.

tries. The right to prescribe off-label drug was defined in Britain and Ireland; b) Medical staff had to take the responsibility of off-label drug use in the country where the duty regulations were formulated; and c) Ten countries published guidelines or statements related to off label drug use by their official departments and academic organizations. And the regulation included the following procedures: firstly, to obtain the relative information and evidence; secondly, to get the informed consent; thirdly, to be approved by the ethics committee and/or pharmacy administration committee; fourthly, to record the reasons and effectiveness of off-label use; fifthly, to monitor the adverse reactions of off-label drug use. Besides monitoring the medical institutes, the pharmaceutical companies had also be monitored which included the following 3 aspects: a) to require companies to train specialized staffs to answer the questions related to off-label drug use; b) to open the contact information of medical departments of companies; and c) to prohibit preaching and advertising the off-label drug use. Conclusion Off-label drug use has its rationality and necessity. To protect the safety of patients, avoid the risk for hospitals and medical staffs, it requires formulating relative regulations soon in order to manage the off-label drug use in China. As a developing country, China is different from the developed countries in health care system. Therefore, when formulating the regulations, it is necessary to perform evidence-based evaluation on each country’s laws, regulations and guidelines about off-label drug use, with Chinese national conditions and experts’ opinions in combination. After a regulation is preliminarily drawn up, it needs to be put into pilot practice, and then revised and spread to the whole country.

Rubber compounds containing Perkadox® 14-40B-PD-S have excellent scorch safety, and under certain conditions one step mixing is possible. Safe processing temperature: 135°C (rheometer ts2 > 20 min.). Typical crosslinking temperature: 175°C (rheometer t90 about 12 min.).Thermal stabilityOrganic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.SADT80°CMethod The Heat Accumulation Storage Test is a recognized test method for thedetermination of the SADT of organic peroxides (see Recommendations on theTransport of Dangerous Goods, Manual of Tests and Criteria - United Nations, NewYork and Geneva).StorageDue to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, Nouryon recommends a maximum storage temperature (Ts max.) for each organic peroxide product.Ts max.30°CNote When stored under strictly recommended storage conditions, Perkadox® 14-40B-PD-S will remain within the Nouryon specifications for a period of at least 12months after delivery.Packaging and transportThe standard packaging is a cardboard box for 25 kg peroxide formulation.

Enzyme/Coenzyme/ 5 x 100 ml α-oxoglutarate GTIN: 05055273200454UV METHODThis is an optimised standard method according to the concentrations recommended by the IFCC.CLINICAL SIGNIFICANCE (1,2,3,4)The aminotransferases are a group of enzymes that catalyse the inter conversions of amino acids and α-oxoacids by transfer of amino groups. AST (aspartate aminotransferase or glutamate oxaloacetatetransaminase) has been found in the cytoplasm and the mitochondria of cells that have been studied. In cases of mild tissue damage, e.g. liver, the predominant form of serum AST is that from the cytoplasm, with a smaller amount coming from the mitochondria. Severe tissue damage will result in more mitochondrial enzyme being released. Elevated levels of AST can signal myocardial infarction, hepatic disease, muscular dystrophy and organ damage.Although heart muscle is found to have the most activity of the enzyme, significant activity has also been seen in the brain, liver, gastric mucosa, adipose tissue and kidneys of humans.The IFCC has now recommended (1980) standardised procedures for AST determinations including:-1. optimization of substrate concentrations.2. Employment of Tris buffers (instead of phosphate, which has beenshown to inhibit recombination of the apoenzyme with pyridoxal phosphate).3. Pre-incubation of combined buffer and serum to allow sidereactions with NADH to occur. 4. Substrate start (α-oxoglutarate)5. Optional pyridoxal phosphate activation.This is an optimised standard method according to the recommendations of the IFCC.PRINCIPLEα-oxoglutarate reacts with L-aspartate in the presence of AST to form L-glutamate plus oxaloacetate. The indicator reaction utilises the oxaloacetate for a kinetic determination of NADH consumption. AST -oxoglutarate + L-aspartate L-glutamate + oxaloacetate MDH oxaloacetate + NADH + H + L-malate + NAD +SPECIMEN COLLECTION AND PREPARATION (5) Serum:- Use serum free from haemolysis.Plasma:- EDTA or heparin can be used as the anticoagulant.Plasma should be separated from cells within one hour after collection.Specimens should be refrigerated if not used immediately:-Specimens stored longer than 3 days should be frozen at -20︒C.REAGENT COMPOSITIONContents Concentrations in the TestR1a.

Note: If the absorbance change per minute is between 0.11 and 0.16 at 340/Hg 334 nm 0.06 and 0.08 at Hg 365 nmuse only the values for the first 2 minutes for the calculation.MANUAL CALCULATIONTo calculate the AST activity, use the following formulae:U/l = 1746 x A 340 nm/min U/l = 1780 x A Hg 334 nm/min U/l = 3235 x A Hg 365 nm/minSTANDARDISATIONRandox Calibration Serum Level 3 is traceable to AST reference material JSCC TS01.QUALITY CONTROLRandox Assayed Multisera, Level 2 and Level 3 are recommended for daily quality control. Two levels of controls should be assayed at least once a day. Values obtained should fall within a specified range. If these values fall outside the range and repetition excludes error the following steps should be taken:1. Check instrument settings and light source.2. Check cleanliness of all equipment in use.3. Check water. Contaminants, i.e. bacterial growth, maycontribute to inaccurate results. 4. Check reaction temperature.5. Check expiry date of kit and contents.6.

The effects of various drugs on AST activity should be taken intoconsideration in the case of patients receiving large doses of drugs.The analytes below were tested up to the following levels and were found not to interfere: Haemoglobin 250 mg/dl Free Bilirubin 25 mg/dl Conjugate Bilirubin 25 mg/dl Triglycerides 1000 mg/dlIntralipid ® 200 mg/dlA list of substances and conditions known to effect AST activity in vivo is given by both Young et al and Friedman et al. Norepresentation is made by Randox Laboratories Ltd regarding the completeness of these lists and the accuracy of the information contained therein.NORMAL VALUES IN SERUM (8,9) +25︒C +30︒C +37︒C Men up to 18 U/l up to 25 U/l up to 37 U/l Women up to 15 U/l up to 21 U/l up to 31 U/lIt is recommended that each laboratory establish its own reference range to reflect the age, sex, diet and geographical location of the population.SPECIFIC PERFORMANCE CHARACTERISTICS The following performance data were obtained using an Rx Monza analyser running at +37o C.LINEARITYThis method is linear up to 562 U/l. If the sample concentration exceeds this value, dilute the sample 1+9 with 0.9% NaCl solution and re-assay. Multiply the result by 10.SENSITIVITYThe minimum detectable concentration of AST with an acceptable level of precision was determined as 9.3 U/l.PRECISIONIntra AssayLevel 2 Level 3Mean (U/l) 35.6 153SD 1.66 1.47CV(%) 4.65 0.96n 20 20Inter AssayLevel 2 Level 3Mean (U/l) 35.6 153SD 1.77 7.10CV(%) 4.96 4.63n 20 20CORRELATIONThis method (Y) was compared with another commerciallyavailable method (X) and the following linear regression equationobtained:Y = 1.07X + 4.9and a correlation coefficient of r = 0.997543 patient samples were analysed spanning the range 28 to 559U/l.REFERENCES1.
