説明

A hydrocarbon fraction was isolated from the chloroform-methanol extract of Susabinori, Porphyra yezoensis, by silica gel column chromatography and preparative thin-layer chromatography.<br>The fraction was identified as liquid paraffin from the results of thin-layer chromatography, UV, IR and NMR analyses.<br>Liquid paraffin occurred not only in dried laver but also in fresh layer.<br>Since liquid paraffin was found to be present naturally in fresh layer, it is necessary that the liquid paraffin test of dried laver, which is now qualitatively performed to check the unlawful liquid paraffin coating on a bamboo screen (a tool for drying fresh laver), must be performed quantitatively.
