Sherwani 1 Department of Chemistry, J.N.V. University, Jodhpur - 342 001 (India). The seed oils from six plant speices were analysed for their fatty acid composition viz. Leucaena leucocephala, Mucuna prurita (Leguminosae), Nigella sativa (Ranunchulaceae), Sisymbrium irio, Brassica juncea (Brassiaceae) and Achyranthes aspera (Amaranthaceae). All the seeds were collected from Arid zone of Rajasthan and their physico chemical characteristics and fatty acid composition were studied by using UV, IR, TLC and HPLC techniques. The oils have been found rich in unsaturated fatty acid and the total unsaturated fatty acids were found in good amount in Nigella sativa and Sisymbrium irio 73.79 and 88.85% respectively. https://www.biotech-asia.org/vol7no2/physico-chemical-analysis-of-six-seed-oils-from-arid-zone-of-rajasthan/ Fatty acid composition; minor oil-seeds
