title: Gas chromatography - mass spectrometry studies of the component composition of carboxylic acids of the rhizomes of Iris medwedewii and Iris carthaliniae (Iridaceae)
abstract: The composition of carboxylic acids of the rhizomes of Iris carthaliniae and Iris medwedewii by the gas chromatography - mass spectrometry method has been studied for the first time. The total content of carboxylic acids for I. carthaliniae was 1.34%, including (%) - 0.65 fatty; 0.36 mono-, di- and tri-carboxylic; 0.33 phenol carboxylic acids. The yield of carboxylic acids for I. medwedewii was 1.58%, including (%) - 0.73 fatty; 0.38 mono-, di- and tri-carboxylic; 0.47 phenol carboxylic acids. T
