Abstract

Aliphatic (2E)-alkenals and alkanals characterized from the fresh leaves of the coriander Gundelia tournefortii were found to possess bactericidal activity against Salmonella choleraesuis ssp. choleraesuis (2E)-Dodecenal (C12) was the most effective against this food-borne bacterium with the minimum bactericidal concentration (MBC) of 6.25 µg/mL (34 µM), followed by (2E)-undecenal (C11) with an MBC of 12.5 µg/mL (74 µM). The time-kill curve study showed that these α,ß-unsaturated aldehydes are bactericidal against S. choleraesuis at any growth stage and that their bactericidal action comes in part from the ability to act as nonionic surfactants.

Gundelia is a genus of plants in the sunflower family. The best known species is Gundelia tournefortii. It is found in the semi-aried areas of Lebanon, Syria, Palestine, Israel, Jordan, Iraq, Iran, Azerbaijan, Armenia, and Anatolia. Gundelia tournefortii is a perennial growing to 0.4 m (1ft 4in). The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects (Aburjai et al. 2001; Abutbul et al. 2005). The leaves, stems, roots, and undeveloped flower buds of G. tournefortii, colloquially known as tumble thistle, are edible when they first sprout in early spring(Samani, Rafieian-Kopaei, and Azimi 2013). The plant becomes progressively drier over the summer, it leaves yellowing and growing spikes. Before dying, it detaches from the root to be pushed around by the wind and disperse its seeds for the following year's harvest. Sold in markets in Jerusalem, Syria, Iraq and Lebanon, it's also gathered in the wild in Turkey (Al-Salt 2012). Among Palestinian citiz
