In this study, the physical and chemical properties of linseed oil and sesame seed oil were measured and compared. The results showed that the nitrogen content, total protein and total amino acids in linseed were 3.27%, 20.39%, 92158.22 μg/g FW, respectively, and 2.79%, 17.43%, 92246.59 μg/g FW in sesame seeds correspondingly. The content of unsaturated fatty acids such as linolenic acid and linoleic acid in linseed was 290.57 μg/g, 0.55 μg/g, and 3326.69 μg/g、0.24 μg/g in sesame seed oil. In addition, the contents of palmitic acid, palmitoleic acid, arachidic acid and heptadecanoic acid in sesame were significantly higher than those in linseed. The contents of ergosterol, β-sitosterol and stigmasterol in linseed were 6.57 μg/g, 972.66 μg/g, and 123.27 μg/g, and 5.62 μg/g, 930.57 μg/g, and 145.67 μg in sesame, which were significantly different. The measurement results of metal elements showed that the metal content of linseed d and sesame seed were both Mg>Ca>Fe>Zn, the content of Fe, Mg and Zn in linseed were both higher than that in sesame seed, the Ca element in sesame seeds was higher than that in linseed. It can be seen that linseed oil and sesame seed oil have their own advantages and have different nutrition and health functions.
