The product Orastan-A from Gaspari Nutrition was analyzed for its steroid content. According to the labeling, it is supposed to contain "5a-Androstano[2,3-c]furazan-17b-tetrahydropyranol ether", also called furazadrol-THP ether. The GC-MS analyses of the liberated steroids (after extraction from the capsule matrix and cleavage of the THP ether, TMS-derivative and underivatized) revealed mass spectra
分析了来自Gaspari Nutrition的产品Orastan-A的类固醇含量。根据标签,它应该包含“ 5a-Androstano [2,3-c] furazan-17b-四氢吡喃醚”,也称为呋喃唑醇-THP醚。所释放的类固醇的GC-MS分析(从胶囊基质中提取并裂解THP醚,TMS衍生物和未衍生的THP醚后)显示出两种成分的质谱,均与标记不一致。因此,类固醇通过质谱,核磁共振波谱和X射线晶体结构分析等不同的分析技术进行表征。它们被鉴定为17β-羟基雄甾烷[3,2-c]异恶唑和-[2,3-d]异恶唑。
