Amino-acid composition of subgenus Artimisia Herbs

Abstract

The genus Artemisia L. (Asteraceae) is represented by 24 species in the flora of Ukraine. Of these, 11 belong to the subgenus Artemisia Less.; 8, to the subgenus Dracunculus Bess.; and 5, to the subgenus Seriphidium Rouy. Biologically active compounds include constituents of essential oils, flavonoids, coumarins, phenolic carboxylic acids, lignans, sesquiterpene lactones, diterpenes, and alkaloids. These have been studied in many species of Artemisia [1]. We established previously features of the constituent composition of essential oils of subgenus Artemisia herbs growing in Ukraine and identified the chemical varieties A. absinthium L., A. vulgaris L., and A. austriaca Jacq., which did not contain thujane derivatives [2,3]. The goal of the present work was to study the quantitative amino-acid (AA) compositions of the herbs of A. vulgaris L., A. abrotanum L., A. annua L., A. absinthium L., and A. austriaca Jacq. collected during flowering in summer 2011 in Lugansk and Kharkov District
