Chemical composition of seeds of two minor oil crops, flax (Linum usitatissimum L.) and oil hemp (Cannabis sativa L.) cultivated in Finland were analyzed and compared to others. Oilseed flax cultivars were Abacus, Aries, Comtess, Heljä, Helmi, Laser, Sunrise, and Taurus, three fiber flax cultivars were Belinka, Martta and Snaigiai. Oil hemp cultivar was Finola, a Finnish cultivar with low cannabinoids content. Oil content was higher in oil flax cultivars (42.2-48.8 mg 100 g^-1) than in fiber flax (34.8-42.2 mg 100 g^-1) and oil hemp (34.6 mg 100 g^-1) cultivars. Protein contents were lower in high oil flax cultivars than in fiber flax cultivars. Very great difference between the species was in chlorophyll content, which was much higher in oil hemp (138.3 mg kg^-1) than in oilseed (0-6.8 mg kg^-1) or fiber flax (5.9-11.0 mg kg^-1) cultivars. Oil hemp is so late in Finland that all seeds do not ripen well. Cadmium contents of oilseed (0.390-0.797 mg kg^-1) and fiber flax (0.497-0.600 mg kg^-1) cultivars were much higher than those of oil hemp (0.020 mg kg^-1). Oil hemp cultivar Finola did not accumulate cadmium from the soil. Lead contents were low.
