The chemical composition in the seed of Taxus chinensis var. mairei was reported in this paper. The constituents in 100 g seed (DW) of T. chinensis var. mairei contained protein 9.92 g, fat 72.86 g, starch 4.15 g, soluble carbohydrate 0.38 g and 9.10 g amino acids of the protein. The ratio of essential amino acids to total amino acids was 28.05 %. Oleic acid and linoleic acid accounted for 48.4 % and 42.2 % in seed oil, respectively. The macronutrients in 100 g seed (DW) included N 1 587.2 mg, P 565.4 mg, K 261.1 mg, Ca 18.4 mg and Mg 350.5 mg. The order of the micronutrients contents in the seed was Zn>Fe>Na>Cu >Mn. Tab 4 , Ref 6
