AbstractThis paper focused on the main composition of Cephalotaxus fortunei nuts, the physicochemical property of its oils, the fatty acid profiles and the content of alkaloids and tocopherol in the nuts oils. And these elements were compared among three kinds of C. fortunei nuts and their oil. The results showed the C. fortunei nuts contained about 65 % crude oil. Meanwhile, the content of crude protein, crude fiber, moisture, ash and reduced sugar were presented, respectively. The important physicochemical indicators of the crude C. fortunei nuts oils were presented, including specific gravity, refractive index, viscosity, acid value and saponification value, etc. The contents of alkaloids were 0.41 % in NUT1, 0.24 % in NUT2 and 0.31 % in NUT3. The contents of tocopherol were low. The analysis of the fatty acid composition showed that the three kinds of oils were all rich in unsaturated fatty acids, oleic acid and linoleic acid, and the main triacylglycerols were dioleoyl‐monolinoleoyl (OLO) and triolein (OOO). This work might help with the exploration of the applications of C. fortunei nuts and its oil.
