The present investigation has been carried out to determine the proximate composition, amino acids, metal contents, oil composition as well as the antioxidant capacity of the seeds of Ipomoea hederacea Jacq. and Lepidium sativum L. Proximate composition indicated a great difference in oil (14.09 +/- 0.66, 28.03 +/- 1.05) and fibre (16.55 +/- 0.31, 6.75 +/- 1.20) contents for I. hederacea and L. sativum, respectively. Fatty acid profile indicated that oleic acid (19.50 +/- 0.37, 30.50 +/- 0.16) and linoleic acid (52.09 +/- 0.48, 8.60 +/- 0.38) are the major fatty acids. gamma-Tocopherol and delta-tocopherol (28.70 +/- 0.14, 111.56 +/- 0.37) were the most abundant in the seed oil of I. hederacea and L. sativum, respectively. Results of TEAC, FRAP and TRAP antioxidant assays indicated that L. sativum has much greater antioxidant potential than I. hederacea.
