Chemical Composition of Hexane Extract of Different Parts of Anthemis Talyschensis and Its Potential To Use in Sunscreen Products

In this study, both the presence and concentration of some unsaturated compounds in hexane extracts of different parts of anthemis talyschensis showing absorption at wavelength 280450 nm were surveyed, with the view of possibly using extracts of this plant in new formulations of sunscreen creams. the hexane extracts of flower, leaf and stem of a. talyschensis , collected from northwest iran, were obtained using a soxhlet apparatus. the fatty acids were derivatized to methyl esters and were determined by gas chromatography/flame ionization detector (gc/fid) and gas chromatography/mass spectrometry (gc/ms) systems. the chemical analysis resulted in identification of 14, 9 and 29 constituents, comprising about 99.5, 97.1 and 98.2% of the total constituents in hexane extracts of flower, leaf and stem, respectively. the main unsaturated constituents in the hexane extract of a. talyschensis flower were 9, 12octadecadienoic acid, 9octadecenoic acid and 6, 9, 12octadecatrienoic acid while the leaf's extract contained 9, 12octadecadienoic acid and 9octadecenoic acid no unsaturated compounds were detected in the stem. the ratios of unsaturated fatty acid /saturated fatty acid were 13.6, 9.3 and 0 in extracts of the flower, leaf and stem, respectively, but the total amounts in the leaf were much greater. it can be concluded the leaf extract is more likely to be suitable for producing sunscreens creams than others.
