Abstract: Nutritional components，amino acid and mineral elements composition in leaves，stem and roots of Ficus pandurata var. hoiophylla were thoroughly investigated. To further our study，we also measured the content of flavonoid in this plant. The results were as follows: in leafs，the contents of crude protein，crude fat，crude fiber，total sugar，free amino acid and aqueous extracts were 174.6，14.3，167.4，171.4，2.2 and 257.7 gkg－1 respectively，and vitamin C content was 241.3 mgkg－1；the contents of mineral elements including Cr，Mn，Fe，Cu，Zn，As，Se，Ag，Cd，Hg and Pb were 16.14，551.76，1 060.78，22.79，218.42，2.85，3.32，0.95，4.75，0.75，12.82 mgkg－1 respectively. In stems，the detectable contents of protein，crude fat，crude fiber，total sugar，free amino acid and aqueous extracts were 71.9，5.2，450.7，161.9，1.6，123.7 gkg－1 respectively，and vitamin C 135.6 mgkg－1. Measurable contents of Cr，Mn，Fe，Cu，Zn，As，Se，Ag，Cd，Hg and Pb were 17.18，56.64，550.14，12.53，82.64，1.86，0.00，19.03，1.86，2.32 and 6.96 mgkg－1 respectively. In roots，the contents of crude fiber，crude protein，total sugar，crude fat，free amino acid and aqueous extracts were 368.2，91.1，149.9，7.4，3.4 and 170.3 gkg－1 respectively and vitamin C 140.4 mgkg－1. Detectable contents of Cr，Mn，Fe，Cu，Zn，As，Se，Ag，Cd，Hg and Pb were 15.44，72.47，672.38，23.16，461.41，2.57，1.72，0.86，5.58，0.85 and 29.16 mgkg－1 respectively. Finally，we investigated the total flavonoid contents of Ficus pandurata var. hoiophylla in leaves，stem，and roots，which were 20.85，7.44 and 22.02 mgkg－1 respectively. The findings indicated that Ficus pandurata var. hoiophylla played a positive role in health protection for its nutritive value.［Ch，4 tab. 12 ref.］
