| Popis: | Extraction procedures of selenium compounds applied to solid biological samples (CRM 186: pig kidney, CRM 402: white clover and a selenium enriched yeast) are discussed. Enzymic hydrolysis led to high recoveries (57% to 92%, depending on the sample). A hyphenated High Performance Liquid Chromatography-Electrothermal Atomic Absorption Spectrometry technique is used to study the speciation of selenium in the enzymic extracts. Organic compounds: selenomethionine and selenocystine are found as major components in these samples, 39%, 56% and 77% for clover, kidney and yeast, respectively. |
