Abstract: To investigate the functional factors of Chinese tallow leaf with accumulated fundamental data in nutritional components, some chemical instrumental methods were used. Quantitative results (g/100g,dry mass) were assaged as ash 6.13～ 10.43, protein 5.13～11.45, lipid 3.82～7.24, fibre 18.64～31.34, aqueous total sugar 13.21～26.72, water-soluble polysaccha- rides 1.24～4.37; flavonoids 1.41～5.81 and total acids 0.0004～0.005 from different varieties in the middle days of November. The trace elements (μg/g, dry mass) were: Zn 32.21～157.15, Cu 18.81～230.94, Fe 95.71～256.05, Mn 287.55～1412.69; while the normal element (mg/g, dry mass) were: N 10.48～23.41, P 0.93～2.04, K 3.75～10.06, Ca 7.68～16.56 and Mg 1.63～6.56. The Chinese tallow belonged to a Mn accumulating plant.

Key words: Chinese tallow leaf, nutritional component, an accumulating manganese plant
