Fatty acid compositions of different organs of Alhagi Pseudalhagi (M.Bieb.) Desv. Ex B. Keller & Shap

Abstract

By employing gas chromatography, the fatty acid contents were determined in the root, stem, and leaf of A. pseudalhagi. The composition of fatty acids varied among the organs of A. pseudalhagi. The unsaturation percentages for each part were 47.78%, 48.17%, and 44.12%, respectively. The dominant fatty acid in leaves and stems was palmitic acid. The content of palmitic acid in these organs varied from 19.25% to 19.69%. The other major fatty acids were γ-linolenic acid in the leaves and lignoceric, oleic acids in the roots. Moreover, ω-6 and ω-3 polyunsaturated fatty acids were found, including cis-linoleic, α-linolenic, and eicosapentaenoic acids.
