Author : Hend E. Wahba, Hemaia M. Motawe, Abeer Y. Ibrahim

The chemical composition of the herb volatile oil, anthocyanins in red flower and fatty acids in seeds of Zinnia pauciflora, family Asteraceae, were studied. Oxygenated compounds were the major volatile oil principle (89.8%) including iso-phytol (38.29%), hexandecanoic acid (12.41%) and spathulenol (9.35%). The major hydrocarbon was heneicosane (0.42%). Two anthocyanins were isolated from red flowers, cyaniding-3-gluco-(4-malonyl)-rhamnoside and cyanidine-3-(\"4-malonyl)-arabinoside. Seed total lipoidal matter represented 7.5% and the major fatty acids; Linoleic acid (34.98%), palmitic acid (17.27%) and oleic (13.33%).
