Seed contents of Coriandrum sativum in Jordan Valley

Abstract

The aim of this research was to determine seed contents of Coriander (Coriandrum sativum). Research was conducted in the Jordan Valley at 150 m below sea level and in northern Jordan at 200 m above. Analyses of fertilized seeds showed that they contain 14.9% protein while non fertilized seeds had a significantly lower content (4.7%). The seeds contain 7.4% oil, which can vary according to strain. The fatty acid composition varied significantly among the seeds from the selected locations. Petroselinic acid was significantly the most concentrated fatty acid (80.10%). This acid (C18:1) can be split to produce C6 (adipic acid) and C12:0 (lauric acid) molecules. Adipic acid is used for the manufacture of a wide range of polymers including high grade engineering plastics; at present it is derived from mineral oil by a process that damages the ozone layer and contributes to the releases of gasses such as N2, which affect global warming. Petroselinic acid is abundant in C. sativum and could be an alternative, more environmentally friendly raw material for use in industry.
