Chromatographic analysis has played an important role in the elaboration of metabolism, degradation and mode of action of a variety of methylenedioxyphenyl derivatives. Thin-layer and gas chromatography have been singularly effective in the separation and identification of isomeric mixtures as well as elaborating the influence of substituents on the basic methylenedioxy moiety to chromatographic behavior.
A variety of chromatographic techniques undoubtedly will be in the forefront of attempts to further elaborate the possible dichotomy of action of the methylene-dioxyphenyl synergists60,122.

The literature is abundant with examples of the remarkable versatility of chromatography for the detection and separation of a wide variety of ureas and thioureas. Thin-layer chromatography with its inherent simplicity of operation, rapidity, high degree of sensitivity and resolution (and utility for “pre-cleanup” prior to gas chromatographic analysis) is rapidly replacing paper chromatography. Gas chromatography is becoming more useful as a method for analyzing residues of compounds of pharmaceutical and agricultural interest in plants, soils and animal tissues and fluids. Its ability for the simultaneous determination of several components, such as isomers, homologs and metabolites during a single operation has been amply demonstrated. The utility of gas chromatography will increase with the possibility of decreasing the thermal instability of ureas by the preparation of suitable derivatives such as trimethylsilyl121, or possibly acetyl derivatives193 (successfully utilized for pesticidal carbamates). The desirability of a satisfactory selective system for nitrogen as suggested by Coulson194 as well as the use of pyrolytic techniques195,196 (utilized in combination with gas chromatography for the analysis of barbiturates) appears to offer enhanced prospects for the greater utility of gas chromatography to urea and thiourea analysis.

Chromatography has been widely used in the studies on plasmalogens. It has been used for the following purposes:
1.
A rapid and simultaneous determination in total lipid extracts of phosphatide classes and their constituent plasmalogens by reaction two-dimensional thin-layer chromatography.
2.
Isolation of neutral plasmalogens by adsorption chromatography.
3.
Separation of molecular species of phosphatide plasmalogens by partition column and argentation adsorption column chromatography.
4.
Separation of derivatives of phosphatide plasmalogens from the accompanying alkyl acyl- and diacyl derivatives by a combination of adsorption and argentation adsorption thin-layer chromatography.
5.
Separation of cis synthetic neutral plasmalogen from the corresponding trans isomer by gas-liquid chromatography or argentation thin-layer chromatography.
6.
Analysis of fatty acid and aldehyde composition of plasmalogens by thin-layer chromatography and gas-liquid chromatography.
A brief review on the chemistry, biochemistry and synthesis of plasmalogens is included.
