Abstract

An inter-laboratory study was performed in eight laboratories to evaluate the simultaneous quantification method for HT-2 toxin (HT-2), T-2 toxin (T-2), diacetoxyscirpenol (DAS), neosolaniol (NES), 3-acetyldeoxynivalenol (3-AcDON), 15-acetyldeoxynivalenol (15-AcDON), deoxynivalenol (DON), deoxynivalenol-3-glucoside (D3G), nivalenol (NIV), and fusarenon-X (FUS-X) in feed. The mycotoxins in the samples were extracted with hydrous acetonitrile, purified using a multifunctional column (InertSep^® VRA-3) and a phospholipid removal column (Hybrid SPE^®-Phospholipid), and then quantified using liquid chromatography-tandem mass spectrometry (LC-MS/MS) with atmospheric pressure chemical ionisation mode. The mean recovery, repeatability, reproducibility, and Horwitz ratio from the inter-laboratory validation study were 99.8-109%, 3.1-9.8%, 4.3-9.8%, and 0.19-0.45, respectively, for type A trichothecenes (HT-2, T-2, DAS, and NES). Those values for type B trichothecenes (3-AcDON, 15-AcDON, DON, NIV, and FUS-X) were 89.9-116%, 3.4-9.1%, 5.6-14%, and 0.25-0.70, and the values for modified mycotoxin (D3G) were 78.2-96.7%, 3.5-6.4%, and 13-22%, respectively.

饲料中10种毛霉烯同时定量的实验室间研究。

在8个实验室开展实验室间研究，探讨饲料中HT-2毒素(HT-2)、T-2毒素(T-2)、二乙酰氧基雪腐镰刀醇(DAS)、新茄醇(NES)、3-乙酰脱氧雪腐镰刀醇(3-AcDON)、15-乙酰脱氧雪腐镰刀醇(15-AcDON)、脱氧雪腐镰刀醇(DON)、脱氧雪腐镰刀醇-3-葡萄糖苷(D3G)、雪腐镰刀醇(NIV)和fusarenon-X (FUS-X)的同时定量方法。样品中的真菌毒素用有水乙腈提取，用多功能柱(InertSep®VRA-3)和磷脂去除柱(Hybrid SPE®-磷脂)纯化，然后用常压化学电离模式的液相色谱-串联质谱(LC-MS/MS)进行定量。A型毛线虫(HT-2、T-2、DAS和NES)的平均回收率、重复性、再现性和Horwitz比值分别为99.8 ~ 109%、3.1 ~ 9.8%、4.3 ~ 9.8%和0.19 ~ 0.45。B型霉菌毒素(3-AcDON、15-AcDON、DON、NIV和FUS-X)的检测值分别为89.9 ~ 116%、3.4 ~ 9.1%、5.6 ~ 14%和0.25 ~ 0.70，改性霉菌毒素(D3G)的检测值分别为78.2 ~ 96.7%、3.5 ~ 6.4%和13 ~ 22%。
