用亚甲基单位保留指数对气-液质谱图进行离线反向文库检索分析的计算机系统(MSSMET),已用于用毛细管柱气-液色谱定性和定量测定两个人尿类固醇排泄量的日变化。取24小时尿液标本和晨间现场尿液标本进行等量检测。大多数主要类固醇代谢物的每日排泄规律是相当一致的(即3α-羟基-5α-雄烷-17-酮,雄酮;3α-羟基-5-β-雄烷-17-酮,硫代乳油酮;3-α,17-α,21-三羟基-5-β-孕烷-11,20-二酮;3α,17α,20β,21‐tetrahydroxy‐5β‐pregnane‐11‐one,β-皮质酮;5β-孕烷-3α,11β,17α,20α,21-戊醇,皮质醇;5β-孕烷-3α,11β,17α,20β,21-戊醇,β-皮质醇),而某些其他类固醇代谢物的排泄模式不太一致(例如,3β-羟基-5-雄烯-17-酮)。使用毛细管柱对选定的质谱图进行反向文库搜索来自动分析尿中类固醇的代谢谱的优缺点。
A computer system (MSSMET), using methylene unit retention indices for an off‐line reverse library search analysis of selected ion chromatograms from gas‐liquid chromatographic mass spectrometric data, has been applied for the qualitative and quantitative determination of daily variations in the excreted levels of urinary steroids of two individuals, using capillary column gas‐liquid chromatography. Aliquots of 24 h urine collections and morning spot urine samples were examined. The daily excretion pattern of most of the major steroid metabolites was fairly consistent from day to day (i.e. 3α‐hydroxy‐5α‐androstane‐17‐one, androsterone; 3α‐hydroxy‐5β‐androstane‐17‐one, etiocheolanolone; 3α, 17α,21‐trihydroxy‐5β‐pregnane‐11,20‐dione, THE; 3α,11β,17α,21‐tetrahydroxy‐5β‐pregnane‐20‐one, THF; 3α,11β,17α,21‐tetrahydroxy‐5α‐pregnane‐20‐one; allo‐THF; 3α,17α,20α,21‐tetrahydroxy‐5β‐pregnane‐11‐one, cortolone; 3α,17α,20β,21‐tetrahydroxy‐5β‐pregnane‐11‐one, β‐cortolone; 5β‐pregnane‐3α,11β,17α,20α,21‐pentol, cortol; 5β‐pregnane‐3α,11β,17α,20β,21‐pentol,β‐cortol), while certain other steroid metabolites had a less consistent excretion pattern (3β‐hydroxy‐5‐androstene‐17‐one, for example). Advantages and disadvantages of using capillary columns for the automated metabolic profile analysis of urinary steroids by reverse library search of selected mass chromatograms.
