Fatty acid composition of Artemisia santolinifolia Turcz. ex Bess of Buryatia flora

For the first time, the chromatographic mass spectrometry has been used to study the qualitative composition and quantitative content of the fatty acids of Artemisia santolinifolia Turch. Ex Bess. at different stages of plant development. The study revealed 25 fatty acids, including 18 saturated and 7 unsaturated. The dominant components are palmitic, linoleic, oleic and α-linolenic acids. Comparison of the composition of fatty acids obtained from samples isolated from plants at different phases of development showed that at the begin-ning of flowering the proportion of SFA (51.80%) is almost equal to the proportion of UFA, (48.20%), at the end of flowering and in the phase of fruiting in both samples the content of SFA (59.44-65.01%) is significantly greater than the UFA (34.98-40.59%).
