pubmed-article:8049010 | pubmed:abstractText | The phospholipidic classes of the natural pulmonary surfactant Curosurf were separated by bidimensional TLC and isolated. Quantitative analysis of each class was made by colorimetric determination of phosphorus. FD/MS and NH3-CI/MS were used to identify individual components. GC was used for qualitative/quantitative analysis of fatty acid moieties as methyl esters, using internal standards, by comparison with authentic samples. | lld:pubmed |
