The chemical composition of Calligonum polygonoides essential oil obtained by hydrodistillation from its fruit and stem was analyzed by GC-MS and reported for first time. Among 48 chemical constituents, 23 and 25 are identified in fruit and stem essential oil of C polygonoides comprising 97.3% and 92.2% respectively. The major chemical constituents of the fruit oil are (Z,Z)-9,12-octadecadienoic acid (40.7%), hexadecanoic acid (38.5%), nonacosane (3.5%), tetradecanoic acid (2.0%), heptacosane (1.7%), hentriacontane (1.7%), dodecanoic acid (1.3%) and pentacosane (1.2%) are the major components in fruit. While the major components of the stem oil are hexadecanoic acid (42.9%), (Z,Z)-9,12-octadecadienoic acid (26.9%), dodecanoic acid (5.6%), tetradecanoic acid (3.8%), (R)-massoia lactone (1.7%), nonanoic acid (1.6%) and pentadecanoic acid (1.3%). Thus, the fatty acids are the predominant portions of the oils. Fourteen chemical constituents are common in the essential oil of both fruit and stem of C. polygonoides. (C) 2013 Elsevier B.V.
