Gas-liquid chromatographic analysis of acids obtained from elder and dandelion

Kroszczyński W., Olszewska E., Świętulska M., Trętowska J.

Acta Chromatographica

2002

No. 12

89-94

Gas chromatography has been used for identification of fatty acids in the leaves of elder and dandelion, in the fruits of elder, and in the roots of dandelion. Acid fractions were isolated by formation of insoluble salts or by ion exchange; methyl esters were then prepared. Some of the acids identified have not previously been reported as constituents of these tissues of elder (e.g. succinic acid, nonanedioic acid) or dandelion (e.g. 5-oxoproline, 9-oxononanoic acid), although some have already been found in other parts of the plants (e.g. in the flowers).
