Rapid examination of cutin acids by gas liquid chromatography

Application of a simple and rapid method for separation of cutin acids, by gas liquid chromatography, if carried out on the methyl esters of their trimethylsilyl derivatives has been found possible without previous, more complicated, separation by thin layer chromatography. For comparative research one chromatogram renders sufficient information. The resemblance between the cutin acids from smooth and from russeted apple skin of “Golden Delicious” has been established again. However, some interesting differences occur between the cutin acid pattern of smooth tissue and tissue scarred by mechanical injury.
